The FDA Does Not Care About You

4 Proofs The FDA Does Not Care About Your Health

The stated mission of the Food and Drug Administration (FDA) is to protect and promote public health through the regulation of everything from food products to pharmaceutical drugs. Based on the agency’s actions (or perhaps their severe lack of real action) however, it is quite apparent that this governmentorganization has a blatant disregard for your health and is most certainly not in the business of ‘promoting’ health. Here are 4 ways in which the FDA has gone against public health and safety.

1. FDA Sits Back as You Consume Mercury in Your Food

The FDA, despite having full access to the studies that were heavily publicized even on mainstream media websites, apparently feels that carcinogenic mercury tainting the food supply is nothing to worry about. Found to be present in over a third of 55 popular brand-name food and beverage products, research has shown that you are most likely consuming mercury if you consume processed food items or many beverage products. High-fructose corn syrup is a main carrier of the harmful element, which is especially concerning when you consider the fact that the average American consumed 37.8 pounds of high-fructose corn syrup in 2008!

Despite experts speaking out and calling on the FDA to come to the aid of the public, the FDA still does nothing.

“Mercury is toxic in all its forms. Given how much high-fructose corn syrup is consumed by children, it could be a significant additional source of mercury never before considered. We are calling for immediate changes by industry and the [U.S. Food and Drug Administration] to help stop this avoidable mercury contamination of the food supply,” the Institute for Agriculture and Trade Policy’s Dr. David Wallinga, a co-author of both studies, said in a prepared statement.


2. FDA Pushes Unlabeled, Genetically Modified Salmon

Back in 2011, Congress took legal action against the approval of genetically modified salmon via blocking the FDA from approving it due to health concerns. Calling for further research, Congress listened to the warnings given by experts over the potential dangers of the genetically modified creation. Known as AquAdvantage,
the creation process of the fish involves a combination of genomes taken from other fish. Using a gene from the pout fish to prevent freezing, and a growth gene from the Chinook salmon to bring forth faster growth, the engineered salmon is ‘enhanced’ to grow much faster.

One concern is that this genetically modified fish could escape from fish farms and threaten the very genetic code of salmon worldwide. What’s more, however, is that the FDA wouldn’t even require labeling of the GM salmon. This means you could be unknowingly consuming AquAdvantage salmon, thanks to the FDA completely ignoring the potential dangers and concerns of the public and experts alike.

3. FDA Allows Carcinogenic Aspartame to Invade Food Supply

The ubiquitous artificial sweetener aspartame is commonly found in gum products, diet sodas, and an increasingly large percentage of ‘sugar-free’ items. Aspartame has been found to wreak havoc on your body, with studies directly tying aspartame consumption to tumor growth.

One study in particular shed light on the cancer-causing effects of aspartame. Performed by researcher Victoria Innes-Brown, the study showed that of 48 rats experimented on, up to 67 percent of all female rats developed tumors roughly the size of golf balls or larger. The male population didn’t do too well either with 21 percent of the males developing similar cancerous growths. The FDA completely ignores this information and allows for aspartame to be consumed across the nation under the name of NutraSweet and Equal as well.

4. FDA Gives Monsanto Complete Freedom

Not only does the FDA give Monsanto unprecedented political power in shoving their genetically modified foods down your throat, but they have also been given the
greenlight to contaminate the United States dairy supply with their genetically engineered growth hormone known as rBGH. Linked to breast and gastrointestinal cancer, the substance has been banned in 27 countries. Unfortunately, it is estimated that around 1/3 of cows in the United States are injected with this synthetic hormone, which means that you have most likely been highly exposed to rBGH if you live in the U.S. or have eaten U.S. dairy products.

Perhaps this has to do with the fact that Monsanto employees have positioned themselves prominently within the FDA?

One example of many is Margaret Miller. Margaret Miller was in charge of preparing the report on rBGH following its approval at Monsanto, she was later the official in charge of reviewing her own report as Deputy Director of Human Safety and Consultative Services. How’s that for protecting and promoting public health?

This is but a very short list of ways in which the FDA has actually endangered public health – by not protecting it. The list could go on and on, discussing their numerous drug approvals that have resulted in deaths, severe side effects, and much more. Amazingly, a large percentage of US pharmaceuticals are actually created overseas in unregulated Chinese factories – many of which the FDA has never even inspected.

FDA Threat: Vitamins, Supplements, & Alternative Health Therapies

  

 healthfreedoms.org

The FDA generously lends its approval to drugs that cause ghastly symptoms and untold damage. Many contain toxic contaminants from China. Vioxx is said to have claimed 70,000 lives. “Yet not one of them was taken off the market until the desired profits of the product manufacturer were realized and not once were criminal charges ever levied at a pharmaceutical company that decided profits were far more important than human lives.”

Consumer reports seek to demonize natural remedies with ambiguous statements like “thought to be linked” and “could be linked” because natural products are not patentable and there are barely any substantial reports of negative consequences. But this is not enough for the FDA to turn public interest against natural health products and close small supplement companies. So the next step involves twisting vitamins, supplements, and alternative health therapies into something “medicinal” to crack down on companies full force. But they never crack down on the real culprits of death and damage.

In the matter of independent testing for new drugs and vaccines, the FDA throws its hands up, “We don’t have the power!” When it comes to natural remedies it will be “Respect our power!”

~ Health Freedoms

Even as the FDA has for decades routinely given a seal of approval to toxic and deadly medications and vaccines, claiming they are safe, and as hundreds and thousands of people, if not millions, have died or have been permanently injured as a result of their incompetence and gross dereliction of duty, this agency continues its assault on natural remedies and aids claiming they need to be regulated by FDA.

While one toxic and deadly medication, such as Vioxx can claim 70,000 lives, the manufacturer is never shut down by the FDA. Merck Pharmaceuticals never pays any fines or penalties. While they may be sued in court for wrongful death, this is only AFTER they have sold enough of their toxin to exceed any long term risk assessment costs.

In other words: Merck knows its product is lethal. It weighs the long term risk. The questions are never those of public safety, possible harm or death from using their product, but rather:

    • Can we sell enough of Vioxx fast enough and at levels
    • High enough to offset what we estimate will be the costs of lawsuits for the people we killed or permanently injured and still make a hefty profit?

healthfreedoms.org

And every pharmaceutical company operates their business under this model which is nothing short of pre-meditated murder in my opinion. While state after state moves to criminalize the alternative therapies and the vitamin and supplement industry, not one state has moved to criminalize the use of toxic and deadly, FDA approved, medications. Not one state, and surely not those Republicans who are colluding state to state to criminalize alternative health practices, has ever suggested holding Merck or any other pharmaceutical company criminally responsible or criminally negligent for the people injured or killed in their respective states as a result of the use of long term risk assessments on the public, rather than safety.

Never in the history of natural and alternative therapies and health practices has any vitamin, mineral, supplement, herb or alternative therapy caused the death of 70,000 people. Not once. In fact, the reports of adverse reactions to natural remedies and health aids is so minimal, there virtually is no report of any consequence.

Because there is no evidence of large scale harm from the use of natural remedies and therapies, a skewed and fabricated report which was promoted by Consumer Reports, using terms such as “May be linked, Could be linked, might be, “is thought to be linked” and other evasive and non-conclusive statements to lead the reader to believe that there is a known and provable link to various diseases and health issues when no such evidence exists. Because these natural products are natural and not patentable and most have been used for centuries without harm, it is imperative to fictionalize some form of threat to justify handing them over to big pharma.

Consumer Reports also stated:

“The Food and Drug Administration has not made full use of even the meager authority granted it by the industry-friendly 1994 Dietary Supplement Health and Education Act (DSHEA).”

The FDA has actually stepped outside of its legal (not lawful) authority which is only concerned with labeling. Every effort has been made by FDA to create regulations and rules that would have no other effect than to expedite the closing of small supplement manufacturers as they move towards redefining nutritional supplements and dietary aids along with alternative health therapies as medicinal.The Consumer Report also states that of the supplements tested many were found to be contaminated with heavy metals and other toxins, including prescription medications. It also says that most of this contamination originates in China….just like the melamine contaminated products.

Did the FDA move to halt these products? No! Do they inspect any Chinese producers? No! Were any penalties levied against Chinese producers? No!

What FDA did do in the case of the melamine contamination was to establish an acceptable amount of melamine in Chinese imports. Melamine is highly toxic at any level.

The use of the words and phrases such as, may, could, might, thought to be, are the same vague words used to justify the use of toxic vaccines and medications. Any of these pharmaceuticals “may, might, could be or may be thought to be” useful in fighting disease, but no one seems able to provide any conclusive evidence that they do, although we do seem to bury a large number of people subjected to them and we have to deal with the long term care for those who survive these things but who are now permanently damaged.

As a result of their continuing protection of, and approval of, untested medications and vaccines producers, is it any wonder the FDA (Food & Drug Administration) is now openly referred to by the public as the “Federal Death Administration”?

This agency has given its approval to medications that have caused heart attacks, strokes, birth defects, autism, neurological disorders, seizures, coma, sudden infant death, infertility, cancer, leukemia, brain damage, dementia, amnesia, liver damage, muscle damage, high blood pressure, hemorrhages, blood clots, blindness, and so many other life threatening or life impairing conditions that it is impossible to list them all. The list of medications and vaccines that have been pulled from the market is extensive. Yet not one of them was taken off the market until the desired profits of the product manufacturer were realized and not once were criminal charges ever levied at a pharmaceutical company that decided profits were far more important than human lives.

This approval is given in lieu of money. It is given while accepting the intentionally skewed testing data provided by the same corporations seeking approval. The FDA rarely, if ever, actually does any independent testing of new drugs and vaccines. This is not a matter of the FDA not having enough authority; they have far more authority than they were ever intended to have.

The problem is that they are a privately owned federal corporation unlawfully empowered to write rules and regulations (law-making) by congress ceding its authority, and as such are autonomous. Nothing in the FDA mandates and guidelines requires them to act in the public interest. And the fact is; they don’t.

Why The Law (allegedly) Forbids The Medicinal Use of Natural Substances

 

According to the FDA’s legal definition, a drug is anything that diagnoses, cures, mitigates, treats, or prevents a disease.

The problem with this definition is that there are numerous substances, as readily available and benign as found on our spice racks, which have been proven by countless millennia of human experience to mitigate, prevent and in some cases cure disease, and which cannot be called drugs according to the FDA.

How can this be? Well, the FDA has assumed for itself Godlike power, requiring that its official approval be obtained before any substance can legally be used in the prevention and treatment of disease.

The FDA’s legal-regulatory control therefore is totalitarian and Napoleonic in construct; what it does not explicitly permit as a medicine is implicitly forbidden.

Historically the FDA has required new drugs undergo expensive and elaborate multi-phased clinical trials, which are out of the grasp of any ordinary interest who might want to demonstrate the efficacy of a non-patentable (and therefore unprofitable) herb, food or spice.

The average out-of-pocket cost for obtaining a new drug approval is US$ 802 million dollars,[1] and therefore an investor putting capital into bringing to market a
substance that does not lend itself to market exclusivity and therefore cannot produce a return on investment, is committing economic suicide, if not also breaking the law. The investor actually has a legally-binding fiduciary responsibility to its shareholders to make a profit. And therefore, capital will not flow into any would-be commodity that can be produced or obtained with ease, including most things that grow freely on this Earth.

It is an interesting footnote in history that shortly after the Declaration of Independence, Congress declared that natural substances, e.g. water or salt, were God’s gift to mankind and that therefore products of nature should be limited in their patent protection. While this was a noble declaration, it has actually been used against those whose rights it would protect. It has forced private interests to synthetically alter natural substances — for instance the burgeoning biotech field of recombinant DNA technology, i.e. genetically modified organisms (GMOs) — for the sole reason that it guarantees them ownership/patent rights.

In fact, a medical system that legally requires it make a profit threatens to destroy and/or incriminate itself if non-patented, non-profitable natural substances or therapies are employed. It also results in so much collateral damage to those it purports to serve that it could rightly be called a modern form of human sacrifice.

As a result, instead of choosing prospective medicines logically: because they work, are easily accessible, and safe, billions of dollars flow in the exact opposite direction, capitalizing only those substances which are unnatural, and therefore while proprietary are almost invariably unsafe, and whose access and administration can be intensively controlled.

Has The Attempt To Co-opt Medicine Through the Drug-Based Model Undone Itself? 

And yet, there is a silver lining to the story. Due to the fact that our bodies are ultimately constructed from the natural things (food, air and water), and obey very strict natural laws such as the well-known principle of chirality (handedness) the fact that all aminoacids in our body turn a beam of polarized light in the left-handed direction (L-lysine) and sugars to the right-handed direction (D-ribose)– one cannot simply create biologically active, synthetic drugs arbitrarily, as a mistake in handedness (or similar property) could be fatal. Nature, therefore, still provides an elegant biomolecular architecture of irreproducible intelligence and complexity, from which synthetic analogs are modeled and/or derivatives are spun.

As a result, billions of dollars of drug industry and government money (i.e. tax payer money) flow into finding lead compounds for drug development.  Nature is put on the rack, if you will, and her secrets teased from her through innumerable animal and test tube experiments, in order to find compounds that can then be converted into synthetic, patented drugs.

Inadvertently, some of the very same companies and interests which require that natural substances not receive the same drug-approval status as synthetic ones, are funding research that prove basic vitamins, foods and spices are as effective or more effective and usually much safer than the drugs  they are
developing to replace or supplant them.  

This means that tens of thousands of studies do exist showing that natural substances may prevent and/or treat disease, at least in the in vitro (test tube) and animal models. These results often confirm traditional uses in Ayurvedic, Chinese and other traditional systems of medicine, and therefore may be compelling enough for individuals or healthcare practitioners to use the information to inform their treatment decisions.

The Case For Curcumin In the Prevention and Treatment of Disease

The government biomedical and life sciences database known as Medline contains over 21 million published study citations, and is accessible to search through engines such as Pubmed.gov. 2.6 million of them contain reference to cancer.  115,000 of them remain after applying the Complementary Medicine filter. 2,625 of them can be found indexed on the GreenMedInfo.com database, referencing 612 natural substances of potential value. Turmeric, and particularly its polyphenolic constituent known as curcumin, which gives the spice its golden hue, is one of the most extensively studied natural compounds of all time, with 4588 references to it on the National Library of Medicine’s bibliographic database known as Medline [as of 2.25.2012]. And yet, despite having been shown to have therapeutic value in over 500 disease states in animal and in vitro studies, it still has not been the subject of extensive human clinical research for the reasons stated above.

GreenMedInfo.com, an open source natural medicine database, has indexed curcumins anti-cancer properties in over 50 cancers, with the top 10 most cancers researched in association with curcumin listed below.

Cancer Number of Articles
Breast Cancer 58
Colorectal Cancer 23
Colon Cancer 51
Prostate Cancer 42
Pancreatic Cancer 24
Cancers: Drug Resistant 40
Lung Cancer 37

As one can see curcumin holds great promise. It has been repeatedly demonstrated to possess simultaneously both chemoprotective/chemosensitizing and radioprotective/ radiosensitizing properties, meaning it is capable of reducing the adverse effects on healthy cells caused by chemotherapy and radiotherapy, as well as enhance the cancer-killing properties of these conventional therapies. It also has an exceptionally high margin of safety, at least an order of magnitude greater than commonly used conventional chemotherapy agents such as 5-fluoruracil.[2] Given these facts curcumin, at the very least, should be considered an ideal candidate for use as an adjuvant in integrative cancer care, and perhaps as a first-line treatment alternative to conventional chemo-agents.

FDA Targets ‘Unproven’ New Supplements While Allowing Harmful GMOs

gaia-health.com

The FDA is seeking to outlaw the majority of supplements created after 1994 until they have been heavily proven to be 100% effective and free of any slight side effects.

Meanwhile, the organization allows for harmful genetically modified ingredients to fill the world’s food supply.

While the FDA’s NDI (New Dietary Ingredient) regulations seek to remove your right to freely purchase powerful superfoods, they are simply not concerned over the fact that GMO food consumption has been linked with severe organ disruption and other health concerns.

Under the new guidelines, every nutritional supplement company will be required to compose and submit a comprehensive NDI (New Dietary Ingredient) documentation for every single ingredient used in each product they are currently selling.

This tedious and ridiculous process will hinder the sales of legitimate nutraceuticals, and removes your free choice to determine which ingredients you find to be the most beneficial to your health.

For example, many unknowing consumers purchase synthetic vitamin brands that are actually endangering their health. One popular example is vitamin E (dl-alpha tocopherol acetate), a petrochemically derived analogue of natural vitamin E which may act as an endocrine disruptor and interfere with the heart-protective natural vitamin E isomer gamma tocopherol. FDA Ignores GMOs, Synthetic Vitamins, and Toxic Fillers Yet Attacks Real Supplements

Of course the FDA says nothing about this, as synthetic vitamins like Centrum climb to the top of the charts and are prominently displayed at pharmacies and grocery stores everywhere. In fact, the FDA had to initially allow for these synthetic vitamins and fillers to be used in these products.

If you have been following the massive anti-Monsanto revolution, then you undoubtedly are also aware that genetically modified ingredients and GMO crops are actually a much greater threat than these synthetic vitamins.

Shockingly, the FDA and the USDA has allowed for Monsanto and other biotech corporations to increasingly modify the planet, with little knowledge on the true long-term consequences of allowing for such a test to be conducted on the global population. Nearly 93% of US soybeans are genetically modified, with other food staples like corn and sugar beets not too far behind.

Time and time again, the true effects of GMO crops and ingredients have exploded out into the public spotlight. More information is being leaked to the press almost daily, and Monsanto is being hit with an unprecedented amount of resistance.

Monsanto’s herbicide Roundup, Roundup Ready crops, and other GM products have consistently been found to:

Apparently this is not compelling enough for the FDA, an organization that finds health-promoting supplements based off of plants that have existed for countless centuries to be a direct danger to human health. Perhaps the FDA does not know that pharmaceuticals have led to the deaths of over 3 million people over the past 27 years, while vitamins have killed zero.

FDA Sits Idle as Other Nations Take Real Action

The FDA has allowed for Monsanto to take over the United States food supply as other nations are taking a stand against the bloated biotech corporation. Monsanto’s Posilac, a genetically modified synthetic hormone injected into cows, has been banned in 27 countries over legitimate health concerns.

As for the United States, it is estimated that around 1/3 of cows in the country are injected with this synthetic hormone. Why? Because the FDA, thanks to Monsanto employees being appointed to key positions within the agency, determined rBGH (Posilac) to be completely safe for human consumption.

France, Hungary, and Peru have all taken direct action against Monsanto and genetically modified foods. Meanwhile the FDA defends Monsanto in direct contrast to the global health revolution, sending back public health by 500 years through harsh and unnecessary NDI regulations that challenge the ability to manufacture powerful supplements and superfoods.

Highly Toxic Mercury Present in Processed Foods, Yet FDA Does Nothing

Natural Society

Why has the FDA ignored the fact that mercury, an element that is highly toxic in all forms, was found in a large number of brand-name processed foods? Specifically, the mercury content was found to be contained in high-fructose corn syrup, which also reportedly contains genetically modified ingredients. Instead of addressing this major public health concern, the FDA is focusing their time on crushing beneficial supplements through ridiculous NDI regulations that threaten the entire infrastructure of the nutraceuticals industry.

Researchers from two U.S. studies reported that about half of tested samples of high-fructose corn syrup contained mercury. Mercury was also found in nearly a third of 55 popular brand-name food and beverage products which listed high-fructose corn syrup as the first-or-second-highest labeled ingredient.

Following the report, organizations like the Institute for Agriculture and Trade Policy called on the FDA for immediate action:

“Mercury is toxic in all its forms. Given how much high-fructose corn syrup is consumed by children, it could be a significant additional source of mercury never before considered. We are calling for immediate changes by industry and the [U.S. Food and Drug Administration] to help stop this avoidable mercury contamination of the food supply,” the Institute for Agriculture and Trade Policy’s Dr. David Wallinga, a co-author of both studies, said in a prepared statement.

Americans Consumed Over 37 Pounds of Mercury-Laden HFCS in 2008

Mercury is toxic in any dosage, but the information becomes even more alarming when you consider the fact that the average American consumed 37.8 pounds of high-fructose corn syrup in 2008! If this is not explosive enough on its own, remember the fact that this is but one source of mercury exposure. CFL light bulbs, mercury-contaminated seafood, and some dental fillings are a few sources of mercury exposure that affect millions of individuals.

The ubiquitous nature of high-fructose corn syrup in processed food products makes it difficult to avoid if you are on a junk food diet that is devoid of essential nutrients. Unfortunately, a large number of people worldwide subscribe to this nutritional program while in the dark regarding the true effects that such a diet can have on the human body. Until the FDA decides to step in (which simply will not happen unless activists make enough noise), protecting yourself and your family against HFCS is your priority. If you eat 100% organic food items, or grow your own organic food, you will not have to worry about toxic high-fructose corn syrup.

It’s time to tell the FDA to focus on the real issues, like toxic elements in our food supply – not health-promoting supplements that have improved livesand boosted immune systems.

Dormancy Period: 2 months up to several years.

An estimated 6 to 7 million people worldwide are infected with T. cruzi Chagas disease. Chagas disease is caused by infection with the protozoan parasite T. cruzi, which is typically introduced into humans through the bite of triatomine bugs, also called “kissing bugs”. When the insect defecates at the bite site, motile T. cruzi forms called trypomastigotes enter the bloodstream and invade various host cells. Over many years, cycles of parasite replication and immune response can severely damage these tissues, particularly the heart and digestive tract.

After the parasite enters through an open wound or mucous membrane, the infectious trypomastigote is found in the bloodstream plasma. The amastigote stage of the parasites is found inside pseudocysts located in muscle or nerve cells. There is a predilection for the myocardium or myenteric plexus of the gastrointestinal tract, where it replicates by binary fission. There are three phases of the disease: acute, indeterminate and chronic. 

Dormancy Period: Unknown.

T. brucei is transmitted between mammal hosts by an insect vector belonging to different species of tsetse fly (Glossina). Transmission occurs by biting during the insect’s blood meal. Trypanosoma brucei is a species of parasitic kinetoplastid belonging to the genus Trypanosoma that is present in sub-Saharan Africa. Unlike other protozoan parasites that normally infect blood and tissue cells, it is exclusively extracellular and inhabits the blood plasma and body fluids. It causes deadly vector-borne diseases: African trypanosomiasis or sleeping sickness in humans, and animal trypanosomiasis or nagana in cattle and horses.

In later stages of a T. brucei infection of a mammalian host the parasite may migrate from the bloodstream to also infect the lymph and cerebrospinal fluids. It is under this tissue invasion that the parasites produce the sleeping sickness.

Dormancy Period: Up to 60 days. Many are asymptomatic.

If symptoms develop, they typically occur 20–40 days after ingestion of sporocysts and during the subsequent migration of sporozoites through the body vessels. Acute lesions (edema, hemorrhages, and necrosis) develop in the affected tissues. The parasite has a predilection for skeletal muscle (myositis), cardiac muscle (petechial hemorrhages of cardiac muscle and serosae), and lymph nodes (edema, necrosis, and hemorrhage).

Humans can experience nausea, vomiting, acute and severe enteritis, or chronic enteritis, but many infections appear to be mild or asymptomatic. Differences depend on the number, and perhaps the species, of sarcocysts ingested. Several cases of sarcocystosis have been detected in patients with various types of cancer. Related to cardiomyopathy, intramuscular sarcocystosis, intestinal sarcocystosis.

Dormancy Period: Days to weeks.

Balamuthia mandrillaris is a free-living amoeba that causes the rare but deadly neurological condition granulomatous amoebic encephalitis (GAE).  B. mandrillaris can infect the body through open wounds or possibly by inhalation. It is distributed throughout the temperate regions of the world.

Upon introduction, the amoeba may form a skin lesion, or in some cases, may migrate to the brain, causing a condition known as granulomatous amoebic encephalitis (GAE), which is usually fatal. This granulomatous feature is mostly seen in immunocompetent patients; immunocompromised individuals exhibit a “perivascular cuffing”. Balamuthia-induced GAE can cause focal paralysis, seizures, and brainstem symptoms such as facial paralysis, difficulty swallowing, and double vision.

Dormancy Period: 1 week to months.

Acanthamoeba spp. are among the most prevalent protozoa found in the environment. They are distributed worldwide, and have been isolated from soil, air, sewage, seawater, chlorinated swimming pools, domestic tap water, bottled water, dental treatment units, hospitals, air-conditioning units, and contact lens cases. Additionally, they have been isolated from human skin, nasal cavities, throats, and intestines, as well as plants and other mammals.

They are opportunistic pathogens able to cause serious and sometimes fatal infections in humans and other animals. Diseases caused by Acanthamoeba include keratitis and granulomatous amoebic encephalitis (GAE). The latter is often but not always seen in immunosuppressed patients. GAE is caused by the amoebae entering the body through an open wound and then spreading to the brain. The combination of host immune responses and secreted amoebal proteases causes massive brain swelling resulting in death in about 95% of those infected, within one week to several months.

Dormancy Period: Up to 9 weeks, or the life of the patient if asymptomatic.

People can get infected with Babesia parasites by the bite of an infected tick, by getting a blood transfusion from an infected donor of blood products, or by congenital transmission (an infected mother to her baby). Ticks transmit the human strain of babesiosis, so it often presents with other tick-borne illnesses such as Lyme disease.

After trypanosomes, Babesia is thought to be the second-most common blood parasite of mammals. Half of all children and a quarter of previously healthy adults with Babesia infection are asymptomatic. People with symptoms usually become ill 1 to 4 weeks after the bite, or 1 to 9 weeks after transfusion of contaminated blood products.

Dormancy Period: Can remain a dormant fungus or years.

This organism infects the mucosa of the nasal cavity, producing a mass-like lesion. This mass appears to be polypoidal in nature with a granular surface speckled with whitish spores. The rhinosporidial mass has been classically described as a strawberry-like mulberry mass. This mass may extend from the nasal cavity into the nasopharynx and present itself in the oral cavity. These lesions commonly cause bleeding from the nasal cavity. R. seeberi can also affect the lacrimal gland and also rarely the skin and genitalia. 

Infection in humans with this organism has been reported from about 70 countries, with the majority of cases (95%) reported from India and Sri Lanka; per capita, Sri Lanka has the highest incidence in the world. The common factor found in these areas was the practice of bathing in common ponds.

Dormancy Period: Up to 12 days, death up to two weeks after exposure. Early and accurate diagnosis is essential.

Naegleria fowleri, also known as the brain-eating amoeba. This free-living microorganism primarily feeds on bacteria but can become pathogenic in humans, causing an extremely rare, sudden, severe, and usually fatal brain infection known as naegleriasis or primary amoebic meningoencephalitis (PAM). A large proportion of reported cases of infection had a history of water exposure, 58% from swimming or diving, 16% from bathing, 10% from water sports such as jet skiing, water-skiing and wakeboarding and 9% from nasal irrigation. Swimmers should also avoid digging or stirring up sediment at the bottom of lakes, ponds and rivers as this is where amebae are most likely to live.

Dormancy Period: Days.

Isosporiasis, also known as cystoisosporiasis, is a human intestinal disease caused by the parasite. Infection often occurs in immuno-compromised individuals, notably AIDS patients. It is usually spread indirectly, normally through contaminated food or water. The infected host then produces an immature form of the parasite in their feces, and when the parasite matures, it is capable of infecting its next host, via food or water containing the parasite.

Infection causes acute, non-bloody diarrhea with crampy abdominal pain, which can last for weeks and result in malabsorption and weight loss. In immunodepressed patients, and in infants and children, the diarrhea can be severe.

Dormancy Period: Up to three weeks, non-symptomatic for weeks.

Giardiasis is a parasitic disease caused by Giardia duodenalis (also known as G. lamblia and G. intestinalis). Infected individuals who experience symptoms (about 10% have no symptoms) may have diarrhea, abdominal pain, and weight loss. Less common symptoms include vomiting and blood in the stool. Symptoms usually begin one to three weeks after exposure and, without treatment, may last two to six weeks or longer.

Giardiasis is one of the most common parasitic human diseases. Infection rates are as high as 7% in the developed world and 30% in the developing world. Symptoms usually begin one to three weeks after exposure and, without treatment, may last two to six weeks or longer. Symptoms typically develop 9–15 days after exposure, but may occur as early as one day. Many people with Giardia infections have no or few symptoms. They may, however, still spread the disease.

Incubation Period: Days.

Dientamoebiasis is a medical condition caused by infection with Dientamoeba fragilis, a single-cell parasite that infects the lower gastrointestinal tract of humans. It is an important cause of traveler’s diarrhea, chronic abdominal pain, chronic fatigue, and failure to thrive in children.

Many individuals are asymptomatic carriers of Dientamoebiasis fragilis. Pathogenic and non-pathogenic variants are proposed to exist. Generally considered not harmful if in balanced population.The most commonly reported symptoms in conjunction with infection with D. fragilis include abdominal pain (69%) and diarrhea (61%). Diarrhea may be intermittent and may not be present in all cases. It is often chronic, lasting over two weeks. The degree of symptoms may vary from asymptomatic to severe, and can include weight loss, vomiting, fever, and involvement of other digestive organs. D. fragilis is not considered to be invasive nor cause cell or tissue damage.

Incubation Period: 1 week

Cyclosporiasis primarily affects humans and other primates. When an oocyst of Cyclospora cayetanensis enters the small intestine, it invades the mucosa, where it incubates for about one week. After incubation, the infected person begins to experience severe watery diarrhea, bloating, fever, stomach cramps, and muscle aches.

Cyclosporiasis is a disease caused by infection with Cyclospora cayetanensis, a pathogenic apicomplexan protozoan transmitted by feces or feces-contaminated food and water. Outbreaks have been reported due to contaminated fruits and vegetables. It is not spread from person to person, but can be a hazard for travelers as a cause of diarrhea.

The parasite sporulation for Cyclosporiasisis is from 8–11 days, making the illness difficult to diagnose. It invades the mucosa, where it incubates for about one week. When examining feces, the unsporulated oocysts can easily be mistaken for fungal spores, and thus can be easily overlooked.

Dormancy Period: 2- 28 days.

Cryptosporidiosis, sometimes informally called crypto, is a parasitic disease caused by Cryptosporidium, a genus of protozoan parasites in the phylum Apicomplexa. It affects the distal small intestine and can affect the respiratory tract in both immunocompetent (i.e., individuals with a normal functioning immune system) and immunocompromised (e.g., persons with HIV/AIDS or autoimmune disorders) individuals, resulting in watery diarrhea with or without an unexplained cough. In immunosuppressed individuals, the symptoms are particularly severe and can be fatal. It is primarily spread through the fecal-oral route, often through contaminated water; recent evidence suggests that it can also be transmitted via fomites contaminated with respiratory secretions.

Dormancy Period: weeks to years.

Blastocystis is a protozoal, single-celled parasite that inhabits the gastrointestinal tracts of humans and other animals. Many different types of Blastocystis exist, and they can infect humans, farm animals, birds, rodents, amphibians, reptiles, fish, and even cockroaches. Blastocystosis has been found to be a possible risk factor for development of irritable bowel syndrome.

Common occurrences of Blastocystosis are both asymptomatic and symptomatic. Most cases of the infection appear to become diagnosed as irritable bowel syndrome. The timescale of infection with the parasite can range from weeks to years. Non-symptomatic humans and animals can act as reservoirs.

Dormancy Period: a few days to the lifetime of the patient.

Balantidiasis is a zoonotic disease and is acquired by humans via the feco-oral route from the normal host, the pig, where it is asymptomatic. Fecally contaminated food and water are the common sources of infection in humans.

Some people infected with Balantidiasis may have no symptoms or only mild diarrhea and abdominal discomfort but others may experience more severe symptoms reminiscent of an acute inflammation of the intestines. Balantidium mostly causes asymptomatic and self-limiting infections. Asymptomatic hosts serve as reservoirs of infection in the community.

Dormancy Period: a few days to a few weeks, but usually it is about two to four weeks.

Most infected people, about 90%, are asymptomatic, but this disease has the potential to become serious. It is estimated that about 40,000 to 100,000 people worldwide die annually due to amoebiasis

Since amoebiasis is transmitted through contaminated food and water, it is often endemic in regions of the world with limited modern sanitation systems, including México, Central America, western South America, South and Southeast Asia, and western and southern Africa.

Amoebiasis / Entamoeba species exist in 2 forms: A dormant parasite (cyst),and an active parasite (trophozoite). They can cause brain problems. Symptoms usually develop within 2 to 4 weeks but can show up later.

Dormancy Period: 3 months, up to 1 year or longer.

For about four weeks, the whipworms feed on blood vessels located within the cecum of the large intestine. Eventually, the whipworms leave the cecum and begin to lay thousands of eggs. These unembryonated eggs are then released from the host through feces. The process from egg ingestion to release takes around 12 weeks. The released eggs become embryonated in approximately nine to twenty-one days and are eventually ingested by another host. Eggs that are passed in the feces, can remain alive in soil for years.

The life cycle from the time of ingestion of eggs to the development of mature worms takes approximately three months. During this time, there may be limited signs of infection in stool samples, due to a lack of egg production and shedding. The female T. trichiura begin to lay eggs after three months of maturity. Worms commonly live for about one year, during which time females can lay up to 20,000 eggs per day.

Dormancy Period: Up to 7 days.

About 11 million humans are infected with Trichinella. The great majority of trichinosis infections have either minor or no symptoms and no complications. Trichinosis. During the initial infection, invasion of the intestines can result in diarrhea, abdominal pain, and vomiting. Migration of larvae to muscle, which occurs about a week after being infected, can cause swelling of the face, inflammation of the whites of the eyes, fever, muscle pains, and a rash. Complications may include inflammation of heart muscle, central nervous system involvement, and inflammation of the lungs.

They may very rarely cause enough damage to produce serious neurological deficits (such as ataxia or respiratory paralysis) from worms entering the central nervous system, which is compromised by trichinosis in 10–24% of reported cases of cerebral venous sinus thrombosis, a very rare form of stroke (three or four cases per million annual incidence in adults). 

Dormancy Period: 2 weeks to several years.

Toxocariasis is an illness of humans caused by the dog roundworm (Toxocara canis) and, less frequently, the cat roundworm (Toxocara cati). These are the most common intestinal roundworms of dogs, coyotes, wolves and foxes and domestic cats. Humans are among the many “accidental” or paratenic hosts of these roundworms.

While this zoonotic infection is usually asymptomatic, it may cause severe disease. There are three distinct syndromes of toxocariasis:

Covert toxocariasis is a relatively mild illness very similar to Löffler’s syndrome. It is characterized by fever, eosinophilia, urticaria, enlarged lymph nodes, cough, bronchospasm, wheezing, abdominal pain, headaches, and/or hepatosplenomegaly.

Dormancy Period: Days to 1 year.

Thelaziasis is the term for infestation with parasitic nematodes of the genus Thelazia. The adults of all Thelazia species discovered so far inhabit the eyes and associated tissues (such as eyelids, tear ducts, etc.) of various mammal and bird hosts, including humans. Thelazia nematodes are often referred to as “eyeworms”. In animal and human hosts, infestation by Thelazia may be asymptomatic, though it frequently causes watery eyes (epiphora), conjunctivitis, corneal opacity, or corneal ulcers (ulcerative keratitis). Infested humans have also reported “foreign body sensation” – the feeling that something is in the eye.

The larvae develop into adults in the eye or surrounding tissues of the host, where they may live for over one year.

Thelazia have been found in various tissues of the orbit (or socket) of the eye, including within the eyelids, in the tear glands, tear ducts, or the so-called “third eyelid” (nictitating membrane) or in the eyeball itself.

Dormancy Period: Lifetime of the patient.

The adult parasitic stage lives in tunnels in the mucosa of the small intestine. Many people infected are asymptomatic at first. Symptoms include dermatitis: swelling, itching, larva currens, and mild hemorrhage at the site where the skin has been penetrated. Spontaneous scratch-like lesions may be seen on the face or elsewhere. If the parasite reaches the lungs, the chest may feel as if it is burning, and wheezing and coughing may result, along with pneumonia-like symptoms (Löffler’s syndrome). The intestines could eventually be invaded, leading to burning pain, tissue damage, sepsis, and ulcers. Stools may have yellow mucus with a recognizable smell. Chronic diarrhea can be a symptom. In severe cases, edema may result in obstruction of the intestinal tract, as well as loss of peristaltic contractions.

Dormancy Period: 12 months to 15 years.

The average adult worm lifespan is 15 years, and mature females can produce between 500 and 1,500 microfilariae per day. The normal microfilarial lifespan is 1.0 to 1.5 years; however, their presence in the bloodstream causes little to no immune response until death or degradation of the microfilariae or adult worms. It is spread from person to person via female biting blackflies of the genus Simulium, and humans are the only known definitive host.

O. volvulus causes onchocerciasis, which causes severe itching. Long-term infection can cause keratitis, an inflammation of the cornea in the eye, and ultimately leads to blindness. Symptoms are caused by the microfilariae and the immune response to infection, rather than the adults themselves.

Dormancy Period: Days to weeks

The infection of these roundworms typically causes no overt symptoms but may sometimes cause a mild dermatitis of the thorax and shoulders. M. streptocerca infections fortunately do not cause any nodules, skin disease, or ocular infections like that of Onchocerca volvulus. However they may become visible just under the skin surface, and perhaps decrease skin health and immunity.

During a blood meal, an infected midge (genus Culicoides) or blackfly (genus Simulium) introduces third-stage filarial larvae onto the skin of the human host, where they penetrate into the bite wound. They develop into adults that reside in body cavities, most commonly the peritoneal cavity or pleural cavity, but also occasionally in the pericardium (M. perstans), subcutaneous tissue (M. ozzardi) or dermis (M. steptocerca).

Dormancy Period: Up to 1 year.

Loa loa filariasis, (Loiasis) is a skin and eye disease caused by the nematode worm Loa loa. Humans contract this disease through the bite of a deer fly (Chrysops spp.) or mango fly. These carriers are blood-sucking and day-biting, and they are found in rainforest-like environments in western and central Africa.

A filariasis such as loiasis most often consists of asymptomatic microfilaremia. Some patients can develop lymphatic dysfunction causing lymphedema. Episodic angioedema (Calabar swellings) in the arms and legs, caused by immune reactions, are common. Loa loa is also called the “African eye worm”. The passage over the eyeball can be sensed, but it usually takes less than 15 minutes. Eyeworms affect men and women equally, but advanced age is a risk factor. Eosinophilia is often prominent in filarial infections. Dead worms may cause chronic abscesses, which may lead to the formation of granulomatous reactions and fibrosis.

Dormancy Period: Possibly days to weeks.

Halicephalobus gingivalis is a free-living saprophagous nematode species. It is a facultative parasite of horses, invading the nasal cavity, and sometimes numerous other areas, where it produces granulomatous masses. On rare occasion, it can infect humans as well, causes a universally lethal meningoencephalitis. Infection of the brain is common, followed by the kidneys, oral and nasal cavities, lymph nodes, lungs, spinal cord, and adrenal gland, and also reports of infection of heart, liver, stomach and bone.

The site of entry for the parasite is thought to be through breaks in the skin or through mucous membranes. This nematode is now distributed worldwide, in all climates. It dwells actively in soil, around plants and other organically rich environments including manure and compost. 

Dormancy Period: Up to 4 weeks.

Gnathostomiasis is transmitted by the ingestion of third-stage larvae from raw or insufficiently cooked second intermediate or paratenic hosts such as freshwater fish, snakes, poultry, or frogs. The incubation period for gnathostomiasis is 3–4 weeks when the larvae begin to migrate through the subcutaneous tissue of the body.

A few days after ingestion epigastric pain, fever, vomiting, and loss of appetite resulting from migration of larvae through intestinal wall to the abdominal cavity will appear in the patient. Migration of parasites in the subcutaneous tissues causing intermittent, migratory, painful, pruritic swellings is known as cutaneous larva migrans. Patches of edema appear after initial symptoms clear and are usually found on the abdomen.

Migration to other tissues causes visceral larva migrans and can result in cough, hematuria, ocular involvement, meningitis, encephalitis and eosinophilia. Eosinophilic myeloencephalitis may also result from invasion of the central nervous system by the larvae.

Dormancy Period: Up to 8 weeks, often asymtomatic.

The disease is spread between people by pinworm eggs. The eggs initially occur around the anus. The period of time from swallowing eggs to the appearance of new eggs around the anus is 4 to 8 weeks. The main symptoms are itching in and around the anus and perineum. One-third of individuals with pinworm infection are totally asymptomatic. The eggs are hardy and can remain infectious, outside the body, in a moist environment for up to three weeks.

They may move onto the vulva and into the vagina, from there moving to the external orifice of the uterus, and onwards to the uterine cavity, fallopian tubes, ovaries, and peritoneal cavity. This can cause inflammation of the vulva and vagina. This causes vaginal discharge and itchiness of the vulva. Pinworms can also enter the urethra, and presumably, they carry intestinal bacteria with them.

Dormancy Period: One year or longer. The first signs of dracunculiasis occur around a year after infection, as the full-grown female worm prepares to leave the infected person’s body.

About a year after the initial infection, the female migrates to the skin, forms an ulcer, and emerges. When the wound touches fresh water, the female spews a milky-white substance containing hundreds of thousands of larvae into the water. Over the next several days as the female emerges from the wound, she can continue to discharge larvae into surrounding water. The larvae are eaten by copepods (small aquatic crustaceans), and after two to three weeks of development, they are infectious to humans again. Infected people commonly harbor multiple worms – on average 1.8 worms per person, but as many as 40 – which will emerge from separate blisters at the same time. 90% of worms emerge from the legs or feet. However, worms can emerge from anywhere on the body.

Humans typically get infected when they unintentionally ingest copepods while drinking water or exposure while swimming. 

Dormancy Period: Possibly days to years.

Ophidascaris robertsi is a nematode (also known as roundworm) usually parasitic in the carpet python (Morelia spilota). It is found in Australia and Papua New Guinea,and possibly Indonesia. Pythons serve as the typical hosts for Ophidascaris robertsi.  Humans and mammals that live near carpet python habitat and forage for native vegetation to cook can be exposed by consuming the roundworm’s eggs.These eggs, which are commonly shed in snake droppings due to the snakes’ diet of infected animals, likely contaminates the grass and soil eaten by small mammals. Other vectors, such as domestic and wild animals, are yet to be investigated.

Doctors theorize that the various symptoms (diarrhea and abdominal pain, along with night sweats and dry cough, lung infection) result from the migration of the parasitic eggs and larva from the bowel, through various other organs, before arriving in the brain.

Dormancy Period: Up to 50 days.

After maturing for approximately 50 days, the juveniles then migrate to the kidneys (typically the right kidney). Upon maturation, D. renale can survive for five years. D. renale is distributed worldwide, but is less common in Africa and Oceania. It affects fish-eating mammals, particularly mink, wolves, coyotes, foxes, dogs, raccoons, and weasels. Human infestation is rare, but results in kidney destruction.

The only means of obtaining a definitive diagnosis is through the identification of D. renale eggs in a patient’s urine. However, obtaining patient history (i.e., if the patient has consumed under-cooked or raw freshwater fish) is an important first step that can be coupled with radiological exams to search for enlarged or calcified kidneys. Urinalysis will likely show hematuria, blood tests may reveal eosinophilia.

D. renale is the largest nematode to parasitize humans. Adult male worms are 20–40 cm long and 5–6 mm wide; females can grow to 103 cm in length with a width of 10–12 mm.

Dormancy Period: 1 month to 2 years.

The incubation period for infection ranges from 1 month to 2 years and typically microfilariae appear before overt symptoms.The accumulation of many infective mosquito bites – several hundreds to thousands – is required to establish infection.   Lymphedema can develop within six months and development of elephantiasis has been reported within a year of infection. Men tend to develop worse symptoms than women. The Brugia mosquito injects larvae into human blood stream. Adult worms can survive in the lymphatic system for 5–15 years. The accumulation of many mosquito bites is required to establish infection.

Dormancy Period: Several years asymptomatic.

Most people are asymptomatic unless heavily infected. Human infection with Baylisascaris procyonis has been relatively rare. However, disease caused by this parasite can be extremely dangerous, causing death or severe symptoms. The parasite has been known to infect more than 90 kinds of wild and domestic animals. Reported disease has primarily afflicted children and almost all cases were a result of the ingestion of contaminated soil or feces, via the oral fecal route. the infection results in the penetration of the gut wall by the larvae and subsequent invasion of tissue, resulting in severe disease. 

This parasite’s eggs are able to live for years, extremely resistant to many disinfectants, and cause serious infections in humans with poor treatment options. Community water supplies are easily susceptible to contamination due to the lack of filtration and treatment methods to get rid of the eggs.

Dormancy Period: Up to 3 years.

Often, people show no overt symptoms but may suffer from intestinal problems. When symptoms do occur, the person is usually infected with a large number of worms. Ascaris lumbricoides is one of the most difficult pathogens to kill (second only to prions), and the eggs commonly survive 1–3 years before hatching.

The A. lumbricoides roundworm lives in the intestine where it lays eggs. Infection occurs when the eggs, too small to be seen by the unaided eye, are eaten. The eggs may get onto vegetables when improperly washed. Ascaris lumbricoides infect and estimated 819 million people worldwide. A lumbricoides is the largest intestinal roundworm and is the most common helminth infection of humans worldwide. The worms lack teeth. However, they can rarely cause bowel perforations by inducing volvulus and closed-loop obstruction. Infestation can be deadly if not treated. Occasionally, a worm can travel through the biliary tree and even into the gallbladder, causing acute cholangitis or acute cholecystitis.

Dormancy Period: If no immediate allergic reaction, more severe digestive reactions may be experienced within a few days.

Anisakiasis is a human parasitic infection of the gastrointestinal tract caused by the consumption of raw or undercooked seafood containing larvae of the nematode Anisakis simplex. Reactions, mostly seen as fish allergies, tend to occur soon after consumption.

Within a few hours of ingestion, the parasitic worm tries to burrow though the intestinal wall, but since it cannot penetrate it, it gets stuck and dies. The presence of the parasite triggers an immune response; immune cells surround the worms, forming a ball-like structure that can block the digestive system, causing severe abdominal pain, malnutrition, and vomiting. Occasionally, the larvae are regurgitated. If the larvae pass into the bowel or large intestine, a severe eosinophilic granulomatous response may also occur one to two weeks following infection, causing symptoms mimicking Crohn’s disease.

Dormancy Period: The incubation period in humans is usually from 1 week to 47 days after infection. Most cases are asymptomatic.

In humans, A. cantonensis is the most common cause of eosinophilic meningitis or meningoencephalitis. Frequently the infection will resolve without treatment or serious consequences, but in cases with a heavy load of parasites the infection can be so severe it can cause permanent damage to the central nervous system or death.

Humans and rats acquire the infection when they ingest contaminated snails or paratenic (transport) hosts including prawns, crabs, and frogs, or raw vegetables containing material from these intermediate and paratenic hosts. After passing through the gastrointestinal tract, the worms enter circulation. The larvae then migrate to the meninges and develop for about a month before migrating to the pulmonary arteries, where they fully develop into adults. The larvae cannot reproduce in humans.

Dormancy Period: May remain undetected for many years, however anemia may be an indicator of long term infection..

Hookworms account for a high proportion of debilitating disease in the tropics and 50–60,000 deaths per year These worms produce an iron deficiency anemia by sucking blood from the host’s intestinal walls.

The infection is usually contracted by people walking barefoot over contaminated soil. In penetrating the skin, the larvae may cause an allergic reaction. It is due to the itchy patch at the site of entry that the early infection gets its nickname “ground itch”. Once larvae have broken through the skin, they enter the bloodstream and are carried to the lungs (however, unlike ascarids, hookworms do not usually cause pneumonia).

Dormancy Period: Up to several years, depending on the vector.

Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. Ticks have up to seven nymphal stages (instars), each one requiring blood ingestion, and as such, Ticks undergo a multihost life cycle. Because of their hematophagous (blood-ingesting) diets, ticks act as vectors of many serious diseases that affect humans and other animals. 

Ticks are extremely resilient animals. They can survive in a near vacuum for as long as half an hour. Their slow metabolism during their dormant periods enables them to go prolonged durations between meals. Even after 18 weeks of starvation, they can endure repeated two-day bouts of dehydration followed by rehydration, but their survivability against dehydration drops rapidly after 36 weeks of starvation.

Dormancy Period: Up to six weeks.

Scabies, also sometimes known as the seven-year itch, is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, In a first-ever infection, the infected person usually develops symptoms within two to six weeks. During a second infection, symptoms may begin within 24 hours. The mites burrow into the skin to live and deposit eggs.The symptoms of scabies are due to an allergic reaction to the mites. Scabies is most often spread during a relatively long period of direct skin contact with an infected person (at least 10 minutes) such as that which may occur during sexual activity or living together. Spread of the disease may occur even if the person has not developed symptoms yet.

Dormancy Period: Up to many years depending on the related vector.

Diagnosis can be challenging as the small size of avian mites make them “barely visible to the unaided eye”. Dermanyssus gallinae can also infest various body parts, including the ear canal and scalp. commonly found in the bedroom or where the patient sleeps, as they prefer to stay close to their host for optimal feeding. D. gallinae generally visit their host for up to 1–2 hours, leave after completing their blood meal, and typically feed every 2–4 days. They are able to move extremely quickly, and can take less than 1 second to bite; enough time to inject their saliva and to induce rash and itching.They locate potential hosts through temperature changes, vibrations, chemical signals and CO2.

They primarily infect egg laying chickens, canaries, sparrows, starlings, pigeons, and poultry and also cats, dogs, hamsters, gerbils. This blood-feeding parasite is broadly distributed, and has been reported on 72 host species of North American birds in 26 families.

Dormancy Period: Up to several years with vectored diseases.

Mosquito-borne diseases or illnesses are caused by bacteria, viruses, or parasites transmitted by mosquitoes. Nearly 700 million people contract mosquito-borne illnesses each year, resulting in more than a million deaths.

Diseases transmitted by mosquitoes include malaria, dengue, West Nile virus, chikungunya, yellow fever, filariasis, tularemia, dirofilariasis, Japanese encephalitis, Saint Louis encephalitis, Western equine encephalitis, Eastern equine encephalitis, Venezuelan equine encephalitis, Ross River fever, Barmah Forest fever, La Crosse encephalitis, and Zika fever, as well as newly detected Keystone virus and Rift Valley fever.

When a mosquito bites a human, it injects saliva and anti-coagulants. With the initial bite to an individual, there is no reaction, but with subsequent bites, the body’s immune system develops antibodies. The bites become inflamed and itchy within 24 hours. Avoid all mosquito bites, but especially those from larger black-and-white mosquitos.

Dormancy Period: Rickettsial pox is generally mild and resolves within 2–3 weeks if untreated. There are no known deaths resulting from the disease. Other vectors have been lab tested but not proven outside the lab.

It can transmit human disease, is associated with causing rodent mite dermatitis in humans and is noted for carrying Rickettsia akari, which causes rickettsialpox. Rodent mites are capable of surviving for long periods without feeding and traveling long distances when seeking hosts. Cases have been reported in homes, libraries, hospitals and care homes. A similar condition, known as gamasoidosis, is caused by avian mites.

No human disease has been definitively found to be naturally vectored by these mites. Lab demonstrations have proved that they are at least capable of vectoring murine typhus, rickettsial pox, tularemia, plague, coxsackievirus, and Q fever, although it has not been known to do so outside the lab. The mite was reported as capable of vectoring human typhus, but these reports are not generally accepted.

Dormancy Period: Adult lice will die within 2 days without a blood meal. Rare vectors in Africa with up to 20 days incubation.

Head lice feed only on human blood and are only able to survive on human head hair. They only spread by human to human contact. When adults, they are about 2 to 3 mm long. When not attached to a human, they are unable to live beyond three days. In Ethiopia, head lice appear to be able to spread louse-born epidemic typhus and Bartonella quintana. Elsewhere head lice do not appear to carry these infections.

During its lifespan of 4 weeks a female louse lays 50-150 eggs. Eggs hatch within 6–9 days, each nymphal stage last for 4–5 days and accordingly the period from egg to adults lasts for 18–24 days. Adult lice live for an additional 3–4 weeks. Although any part of the scalp may be colonized, lice favor the nape of the neck and the area behind the ears, where the eggs are usually laid. Head lice are repelled by light and move towards shadows or dark-colored objects in their vicinity.

Dormancy Period: Several months without food. Numerous dangerous vectors can emerge up to years later.

Fleas feed on a wide variety of warm-blooded vertebrates including dogs, cats, rabbits, squirrels, ferrets, rats, mice, birds, and sometimes humans. Female fleas can lay 5000 or more eggs over their life, an adult flea only lives for 2 or 3 months. Without a host to provide a blood meal. A flea’s life can be as short as a few days, or can live for up to a year and a half, can live for several months without eating, so long as they do not emerge from their puparia.

Fleas are vectors for viral, bacterial and rickettsial diseases of humans and other animals, as well as of protozoan and helminth parasites. Bacterial diseases carried by fleas include murine or endemic typhus and bubonic plague. Fleas can transmit Rickettsia typhi, Rickettsia felis, Bartonella henselae, and the myxomatosis virus. They can carry Hymenolepiasis tapeworms and Trypanosome protozoans. 

Dormancy Period: The total lifespan of a Demodex mite is several weeks, with skin diseases evolving over days or months.

Demodex canis lives on the domestic dog, can become mange, and are easily transferred from them. Demodicosis is most often seen in folliculitis (inflammation of the hair follicles of the skin). It may result in small pustules (pimples) at the base of a hair shaft on inflamed, congested skin.

Demodicosis may also cause itching, swelling, and erythema of the eyelid margins. Scales at the base of the eyelashes may develop. Typically, patients complain of eyestrain. Older people are much more likely to carry face mites; about a third of children and young adults, half of adults, and two-thirds of elderly people carry them. The lower rate in children may be because children produce less sebum, or simply have had less time to acquire the mite. The six-legged larvae hatch after 3–4 days, and the larvae develop into adults in about 7 days. The total lifespan of a Demodex mite is several weeks.

Dormancy Period: Adult louse live for up to 30 days. No vectored diseases are known.

Feeding exclusively on blood, the crab louse usually is found in the person’s pubic hair. Although the louse cannot jump, it can also live in other areas of the body that are covered with coarse hair, such as the peri-anal area, the entire body (in men), and the eyelashes (in children).

The total life cycle from egg to adult is 16–25 days. Adults live for up to 30 days. Crab lice feed exclusively on blood, and take a blood meal 4–5 times daily. Outside the host they can survive for 24–48 hours. Crab lice are transmitted from person to person most commonly via sexual contact, although fomites (bedding, clothing) may play a minor role in their transmission. Crab lice are not known to transmit disease; however, secondary bacterial infection can occur from scratching of the skin. Symptoms of crab louse infestation in the pubic area include itching, redness and inflammation.

Dormancy Period: From vectored pathogens up to 20 days.

Body lice may lay eggs on the host hairs and clothing, but clothing is where the majority of eggs are usually secured. The most important pathogens which are transmitted by them are Rickettsia prowazekii (causes epidemic typhus), Borrelia recurrentis (causes relapsing fever), and Bartonella quintana (causes trench fever). Adult lice can live for about thirty days, but if they are separated from their host they will die within two days.

Dormancy Period: Bug can be dormant up to 12 months. No vectored diseases are known.

Although they move away from the host after feeding, they remain within the confines of their host’s roost, nest or dwelling. They may be considered to be micro-predatory bloodsuckers. Adult bedbugs have been reported to live three to twelve months if in an untreated household situation. The effects of cimicid feeding on the host include causing an immune response that results in discomfort, the transmission of pathogens, secondary infections at the wound site, physiological changes such as iron deficiency, and reduced fitness. Although viruses and other pathogens can be acquired by cimicids, they rarely transmit them to their hosts, unless the host is immune compromised.

Dormancy Period: If progressed to Scrub Typhus, 21 days

Leptotrombidium deliense is considered a dangerous pest in East Asia and the South Pacific because it often carries Orientia tsutsugamushi, the tiny bacterium that causes scrub typhus, which is known alternatively as the Japanese river disease, scrub disease, or tsutsugamushi. The mites are infected by the Rickettsia passed down from parent to offspring before eggs are laid in a process called transovarial transmission. Symptoms of scrub typhus in humans include fever, headache, muscle pain, cough, and gastrointestinal symptoms.

The chiggers’ digestive enzymes in the saliva cause “the intensely itchy welts”. Humans are possible hosts. The length of the mite’s cycle normally lasts two to 12 months. After about six days, the prelarvae grow into their larval stage. the mite may still be attached for up to 3 days. The itching can be alleviated through use of over-the-counter topical corticosteroids and antihistamines. According to Mayo Clinic, the chiggers “fall off after a few days, leaving behind red, itchy welts”, which normally heal on their own within one to two weeks. Hot showers or baths also help reduce itching. 

Dormancy Period: Up to 20 years.

Schistosoma (Schistosomatidae) are responsible for human schistosomosis affecting more than 200 million people in tropical and subtropical countries. Pathology is frequently associated with inflammatory reactions to eggs trapped in various tissues/organs. They can live for 20 years and continue to cause damage. In the initial phase of the infection, early transformed schistosomula are localized in the skin. Most of schistosomula stay localized in the thoracic and cervical spinal cord and only exceptionally migrate to the brain.

Dormancy Period: Up to 5 months.

Echinostoma eggs can survive for about 5 months and still have the ability to hatch and develop into the next life cycle stage. Infection can lead to a disease called echinostomiasis. The flukes by the names of E. revolutum, E. echinatum, E. malaynum and E. hortense are particularly common causes of Echinostoma infections in humans.

Humans can become infected with Echinostoma by eating infected raw or undercooked food, particularly fish, clams and snails. A mild infection may not have any symptoms. If symptoms are present they can include abdominal pain, diarrhoea, tiredness and weight loss.

Dormancy Period: Up to 8 weeks.

The estimated annual mortality and risk of infection are 280,000 and 732 million cases, respectively, worldwide. The schistosomulae circulate in the host blood and turn into adults. Adult worms release eggs into the bloodstream that lodge in the small capillaries of the intestine or bladder, penetrate the wall, and are released in feces or urine, respectively. The cycle then repeats itself.

Schistosoma mekongi is much like Schistosoma japonicum in that adults more frequently in the superior mesenteric veins, but can be found in the central nervous system. The reservoir hosts for Schistosoma mekongi are dogs and pigs. It is believed that S. mekongi is unable to use cattle, such as water buffalo, as an effective reservoir host, unlike its close cousin S. japonicum.

Dormancy Period: 30 years or longer, with a large host of related diseases.

Each pair of flukes deposits around 1500–3500 eggs per day in the vessels of the intestinal wall. The eggs infiltrate through the tissues and are passed in the feces. The severity of S. japonicum arises in 60% of all neurological diseases in schistosomes due to the migration of schistosome eggs to the brain.

Individuals at risk to infection from S. japonicum are farmers who often wade in their irrigation water, fishermen who wade in streams and lakes, children who play in water, and people who wash clothes in streams. Once the parasite has entered the body and begun to produce eggs, it uses the hosts’ immune system (granulomas) for transportation of eggs into the gut. The eggs stimulate formation of granuloma around them. The granulomas, consisting of motile cells, carry the eggs to the intestinal lumen. When in the lumen, granuloma cells disperse leaving the eggs to be excreted within feces. Unfortunately, about two-thirds of eggs are not excreted, instead they build up in the gut. 

Dormancy Period: 4 years or more.

Sexual maturation is attained after 4–6 weeks of initial infection. A female generally lays 500–1,000 eggs in a day. The fluke continuously lays eggs throughout their life. An average lifespan is 3–4 years. Adults are found in the venous plexuses around the urinary bladder and the released eggs travels to the wall of the urine bladder causing haematuria and fibrosis of the bladder. The bladder becomes calcified, and there is increased pressure on ureters and kidneys otherwise known as hydronephrosis. Inflammation of the genitals due to S. haematobium may contribute to the propagation of HIV.

Along with other helminth parasites Clonorchis sinensis and Opisthorchis viverrini, S. haematobium was declared as Group 1 (extensively proven) carcinogens by the WHO International Agency for Research on Cancer (IARC) Working Group on the Evaluation of Carcinogenic Risks to Humans in 2009.

Dormancy Period: Up to 4 weeks.

As of 2021, the World Health Organization reports that 251.4 million people have schistosomiasis. As the leading cause of schistosomiasis in the world, it is the most prevalent parasite in humans. Snails are intermediate hosts. Each female lays approximately 300 eggs a day. It is classified as a neglected tropical disease.

Each schistosomule spends a few days in the skin and then enters the circulation starting at the dermal lymphatics and venules. Here, they feed on blood, regurgitating the haem as hemozoin.The schistosomule migrates to the lungs (5–7 days post-penetration) and then moves via circulation through the left side of the heart to the hepatoportal circulation (>15 days) where, if it meets a partner of the opposite sex, it develops into a sexually mature adult and the pair migrate to the mesenteric veins.The adult female worm resides within the adult male worm’s gynaecophoric canal, which is a modification of the ventral surface of the male, forming a groove. 

Dormancy Period: 30 years or longer, with a large host of related diseases.

Many individuals do not experience symptoms. If symptoms do appear, they usually take 4–6 weeks from the time of infection. Schistosomes can live an average of 3–5 years, and the eggs can survive for more than 30 years after infection. S. haematobium completes it life cycle in humans, as definitive hosts, and freshwater snails, as intermediate hosts, just like other schistosomes. But unlike other schistosomes that release eggs in the intestine, it releases its eggs in the urinary tract and excrete along with the urine.

Adults are found in the venous plexuses around the urinary bladder and the released eggs travels to the wall of the urine bladder causing haematuria and fibrosis of the bladder. The bladder becomes calcified, and there is increased pressure on ureters and kidneys otherwise known as hydronephrosis. Inflammation of the genitals due to S. haematobium may contribute to the propagation of HIV.

Dormancy Period: Infections can persist for 20 years or more, with few obvious symptoms, while related diseases progress.

About 22 million people are estimated to be affected yearly worldwide. It is particularly common in East Asia. Paragonimiasis is easily mistaken for other diseases with which it shares clinical symptoms, such as tuberculosis and lung cancer. As hermaphrodites, they produce and fertilise their own eggs that are released through the respiratory tract. The eggs are excreted to the environment either through the sputum or by being swallowed and passed out along with the faeces. Time from infection to laying of eggs is 65 to 90 days. Infections may persist for 20 years in humans.

Dormancy Period: Infection can last the lifetime of the patient.

The free metacercariae penetrate the intestinal mucosa and enter the bile ducts. Migration into the bile ducts takes 1–2 days. They start feeding on the bile secreted from the liver, and gradually grow. They become adults in about a month, and start laying eggs. The average lifespan of an adult fluke is 30 years. An individual fluke can produce 4,000 eggs in a day.

O. viverrini is a hermaphroditic liver fluke. Similar to C. sinensis and O. felineus, it requires three different hosts to complete its lifecycle. Freshwater snails are the first intermediate hosts, and freshwater fishes belonging to the family Cyprinidae are second intermediate hosts in which larval development occurs. Fish–eating (piscivorous) mammals, including humans, dogs, and cats, act as definitive hosts, in which sexual reproduction occurs. As a result of poor sanitation practices and inadequate sewerage infrastructure, O. viverrini-infected people pass the trematode’s eggs in their feces into bodies of fresh water from where snails become infected.

Dormancy Period: The incubation period is around 14 days and infestation may persist for more than one year.

After ingestion of fish infected with M. conjunctus, about 1–15 days are needed for symptoms to occur, namely for eggs to be detected in the stool. When untreated, symptoms may last from 3 days to 4 weeks.

The first intermediate host of M. conjunctus is a freshwater snail, Amnicola limosus.The second intermediate host is a freshwater fish.

The definitive hosts are fish-eating mammals such as domestic dogs, domestic cats, wolves, red foxes, gray foxes, coyotes, raccoons, muskrats, American minks, fishers, or bears. It can also infect humans, where it lives in the bile duct and in the gallbladder.

Dormancy Period: Up to 2 months.

Symptoms typically begin 30 to 60 days after exposure. Most infections are light, almost asymptomatic. In heavy infections, symptoms can include abdominal pain, chronic diarrhea, anemia, ascites, toxemia, allergic responses, sensitization caused by the absorption of the worms’ allergenic metabolites can lead to intestinal obstruction and may eventually cause death of the patient. The largest intestinal fluke of humans, growing up to 7.5 cm (3.0 in) long. 

The parasite infects an amphibic snail (Segmentina nitidella, Segmentina hemisphaerula, Hippeutis schmackerie, Gyraulus, Lymnaea, Pila, Planorbis (Indoplanorbis)) after being released by infected mammalian feces; metacercaria released from this intermediate host encyst on aquatic plants like water spinach, which are eaten raw by pigs and humans. Water itself can also be infective when drunk unboiled (“Encysted cercariae exist not only on aquatic plants, but also on the surface of the water.”)

Dormancy Period: Up to 14 days.

Flukes attach to the wall of the small intestine, but are often asymptomatic unless in large numbers. Infection can occur from eating a single infected fish source. The incubation period is around 14 days and infestation may persist for more than one year. In acute metagonimiasis, clinical manifestations are developed only 5–7 days after infection. 

Transmission requires two intermediate hosts, the first of which is snails, most commonly of species Semisucospira libertina, Semiculcospira coreana, and Thiara granifera.

Infection is acquired through the secondary intermediate host, fish, that have not been thoroughly cooked. Metacercariae encyst under the scales or in the flesh of fish from fresh or brackish water. Sweetfish (Pecoglossus altevelis) is one of the most common fish species infected, but others include the golden carp (Carassius auratus), common carp (Cyprinus carpio), Zacco temminckii, Protimus steindachneri, Acheilognathus lancedata, and Pseudorashora parva.

Dormancy Period: Up to 3 months.

The disease progresses through four distinct phases; an initial incubation phase of between a few days up to three months with little or no symptoms; an invasive or acute phase which may manifest with: fever, malaise, abdominal pain, gastrointestinal symptoms, urticaria, anemia, jaundice, and respiratory symptoms. The disease later progresses to a latent phase with less symptoms and ultimately into a chronic or obstructive phase months to years later. Humans are infected by eating water-grown plants, primarily wild-grown watercress in Europe or morning glory in Asia. Infection may also occur by drinking contaminated water with floating young fasciola or when using utensils washed with contaminated water. Cultivated plants do not spread the disease in the same capacity. Human infection is rare, even if the infection rate is high among animals. Especially high rates of human infection have been found in Bolivia, Peru and Egypt.

Dormancy Period: Up to 2 years.

The main reservoirs for Dicrocoelium dendriticum are sheep, cows, land snails and ants. However, Dicrocoelium dendriticum has also been found in goats, pigs and even llamas and alpacas. Infection is often asymptomatic. Most Dicrocoelium dendriticum infections of the biliary tree produce only mild symptoms. The incubation period is 1 day to 2 weeks. In this environment, D. dendriticum eggs are highly resistant and remain infectious for up to 20 months. Due to the highly specific nature of this parasite’s life cycle, human infections are generally rare.

Dormancy Period: Up to 25 years.

Clonorchiasis is endemic in the Far East, especially in Korea, Japan, Taiwan, and Southern China. The infection follows the ingestion of undercooked or pickled freshwater fish imported from one of the endemic areas and containing metacercariae. Humans become infected by eating infected fish that has been undercooked, smoked, pickled, or salted. Adult C. sinensis worms can inhabit the bile ducts of humans for 20–25 years without any clear clinical symptoms. This, in addition to the nonspecific symptoms infected persons may develop, can lead to missed diagnoses.

Dormancy period: Up  to six months – check before pregnancy.

Zika is a mosquito-borne flavivirus that can cause congenital defects, including microcephaly. Zika causes symptoms similar to other viral diseases spread through mosquito bites, like dengue and chikungunya. Many people infected with Zika virus will not have symptoms or will only have mild symptoms. Rarely, Zika infection can cause Guillain-Barré syndrome (GBS) or severe disease affecting the brain. Most Zika virus infections are asymptomatic.

Symptoms may include fever, red eyes, joint pain, headache, and a maculopapular rash. Symptoms generally last less than seven days. Most people who are infected have no or few symptoms. Otherwise the most common signs and symptoms of Zika fever are fever, rash, conjunctivitis (red eyes), muscle and joint pain, and headache, which are similar to signs and symptoms of dengue and chikungunya fever. The disease spreads from mother to child in the womb and can cause multiple problems, most notably microcephaly, in the baby.

Dormancy period: 3-6 days

The disease is caused by the yellow fever virus and is spread by the bite of an infected mosquito. It infects humans, other primates, and several types of mosquitoes.Iit is spread primarily by Aedes aegypti, a type of mosquito found throughout the tropics and subtropics.

Yellow fever is a viral disease of typically short duration. In most cases, symptoms include fever, chills, loss of appetite, nausea, muscle pains—particularly in the back—and headaches. Symptoms typically improve within five days. In about 15% of people, within a day of improving the fever comes back, abdominal pain occurs, and liver damage begins causing yellow skin. If this occurs, the risk of bleeding and kidney problems is increased.

In 15% of cases, people enter a second, toxic phase of the disease characterized by recurring fever, this time accompanied by jaundice due to liver damage, as well as abdominal pain. Bleeding in the mouth, nose, eyes, and the gastrointestinal tract cause vomit containing blood, hence one of the names in Spanish for yellow fever, vómito negro (“black vomit”). 

Dormancy period: Up to 30 days

Co-test with Salmonella Rapid Test.

Typhoid fever, or typhoid, is caused by Salmonella enterica serotype Typhi bacteria, also called Salmonella typhi. Typhoid is usually spread through the ingestion of contaminated food or water. Symptoms vary from mild to severe, and usually begin six to 30 days after exposure.

Often there is a gradual onset of a high fever over several days. This is commonly accompanied by weakness, abdominal pain, constipation, headaches, and mild vomiting. Some people develop a skin rash with rose colored spots. In severe cases, people may experience confusion. Without treatment, symptoms may last weeks or months. Diarrhea may be severe, but is uncommon. Other people may carry it without being affected, but are still contagious. Typhoid fever is a type of enteric fever, along with paratyphoid fever. Salmonella enterica Typhi is believed to infect and replicate only within humans.

Dormancy Period: 7-10 days, or in dormancy the lifetime of the patient.

Found worldwide, T. gondii is capable of infecting virtually all warm-blooded animals. In humans, particularly infants and those with weakened immunity, T. gondii infection is generally asymptomatic but may lead to a serious case of toxoplasmosis. T. gondii can initially cause mild, flu-like symptoms in the first few weeks following exposure, but otherwise, healthy human adults are asymptomatic.

This asymptomatic state of infection is referred to as a latent infection, and it has been associated with numerous subtle behavioral, psychiatric, and personality alterations in humans. Behavioral changes observed between infected and non-infected humans include a decreased aversion to cat urine (but with divergent trajectories by gender) and an increased risk of schizophrenia. Preliminary evidence has suggested that T. gondii infection may induce some of the same alterations in the human brain as those observed in rodents. Tissue cysts can be maintained in host tissue for the lifetime of the animal or human.

Dormancy Period: Several years in asymptomatic patients.

Trichomonas is a genus of anaerobic excavate parasites, and is estimated to be the most prevalent non-viral STI worldwide. Infection rates in men and women are similar but women are usually symptomatic, while infections in men are usually asymptomatic. Transmission usually occurs via direct, skin-to-skin contact with an infected individual, most often through vaginal intercourse. 160 million cases of infection are acquired annually worldwide.

Some of the complications of T. vaginalis in women include: Preterm delivery, low birth weight, and increased mortality as well as predisposing to HIV infection, AIDS, and cervical cancer. T. vaginalis has also been reported in the urinary tract, fallopian tubes, and pelvis and can cause pneumonia, bronchitis, and oral lesions. Condoms are effective at reducing, but not wholly preventing, transmission. Medication should be prescribed to any sexual partner(s) as well because they may be asymptomatic carriers.

Dormancy Period: Up to 7 days.

About 11 million humans are infected with Trichinella. The great majority of trichinosis infections have either minor or no symptoms and no complications. Trichinosis. During the initial infection, invasion of the intestines can result in diarrhea, abdominal pain, and vomiting. Migration of larvae to muscle, which occurs about a week after being infected, can cause swelling of the face, inflammation of the whites of the eyes, fever, muscle pains, and a rash. Complications may include inflammation of heart muscle, central nervous system involvement, and inflammation of the lungs.

They may very rarely cause enough damage to produce serious neurological deficits (such as ataxia or respiratory paralysis) from worms entering the central nervous system, which is compromised by trichinosis in 10–24% of reported cases of cerebral venous sinus thrombosis, a very rare form of stroke (three or four cases per million annual incidences in adults). Trichinosis can be fatal depending on the severity of the infection; death can occur 4–6 weeks after the infection, and is usually caused by myocarditis, encephalitis, or pneumonia.

Dormancy period: Up to 12 days.

Scrub typhus is a mite-borne disease caused by a bacteria known as Orientia tsutsugamushi and transmitted by chiggers – larvae that grow into mites, in rural and forested areas of the Asia-Pacific region. Chiggers often pick up the bacteria when they feed on the skin cells of infected rats or mice. It can cause fever, breathing difficulty, heart palpitations, or sudden cardiac death. The bacteria’s incubation period inside the body is about 6-10 days. Symptoms may start suddenly at around 10-12 days after the bite.

Signs and symptoms include fever, headache, muscle pain, cough, and gastrointestinal symptoms. More virulent strains of O. tsutsugamushi can cause hemorrhaging and intravascular coagulation. Morbilliform rash, eschar, splenomegaly, and lymphadenopathies are typical signs. Leukopenia and abnormal liver function tests are commonly seen in the early phase of the illness. Pneumonitis, encephalitis, and myocarditis occur in the late phase of illness. It has particularly been shown to be the most common cause of acute encephalitis syndrome. Untreated cases are often fatal.

Dormancy period: From 6 hours to 6 days, and up to several weeks.

Salmonella is a bacterial pathogen that causes Salmonellosis. Salmonella bacteria typically live in animal and human intestines and are shed through feces. Humans become infected most frequently through contaminated water or food. Salmonella is notorious for its ability to survive desiccation and can persist for years in dry environments and foods. Symptoms usually begin six hours to six days after infection and last four to seven days. However, some people do not develop symptoms for several weeks after infection and others experience symptoms for several weeks. Multidrug-tolerant mutant Salmonella enter a near-dormant state protected from immune-mediated genotoxic damages.

Most infections are due to the ingestion of food contaminated by feces. Typhoidal Salmonella serotypes can only be transferred between humans and can cause foodborne illness as well as typhoid and paratyphoid fever. Typhoid fever is caused by typhoidal Salmonella invading the bloodstream, as well as spreading throughout the body, invading organs, and secreting endotoxins (the septic form). 

Dormancy period: Up to 23 days.

Rubella, or German measles or scarlet fever, is a mild viral infection that typically occurs in children and non-immune young adults. Rubella is highly contagious from person to person, transmitted primarily through direct or droplet contact from nasopharyngeal secretions. Humans are the only natural hosts.

The average incubation period of rubella virus is 12 to 23 days. People infected with rubella are most contagious when the rash is erupting. But they can be contagious from 7 days before to 7 days after the rash appears. About 25% to 50% of infections are asymptomatic.

Rubella is usually spread from one person to the next through the air via coughs of people who are infected. People are infectious during the week before and after the appearance of the rash. Babies with CRS may spread the virus for more than a year. Only humans are infected. Insects do not spread the disease. Once recovered, people are immune to future infections. Rubella infection of children and adults is usually mild, self-limiting, and often asymptomatic. 

Dormancy period: Typically up to 3 months. This period may be as short as four days or longer than six years, depending on the location and severity of the wound and the amount of virus introduced.

Rabies is a zoonotic disease (jumps from animal to human) that is caused by infection with viruses of the Lyssavirus genus, which are transmitted via the saliva of an infected animal. Dogs are the most important reservoir for rabies viruses, and dog bites account for >99% of human cases. When an individual with rabies develops symptoms, the disease is nearly always fatal. Two classical forms of rabies are generally recognized: furious (also called encephalitic) and paralytic.

Incubation periods can vary considerably, although most patients develop symptoms 20–90 days after exposure. Rabies can lay dormant in the body up to 6 years. Rabies causes about 59,000 deaths worldwide per year, about 40% of which are in children under the age of 15. More than 95% of human deaths from rabies occur in Africa and Asia. Its100% fatal after onset of symptoms.

Dormancy period: Up to 4 weeks.

The following information is biased by the CDC. Monkeypox is a zoonotic virus belonging to the Orthopoxvirus genus, making it closely related to the variola, cowpox, and vaccinia viruses. Symptoms of mpox in humans include a rash that forms blisters and then crusts over, fever, and swollen lymph nodes. The virus is transmissible between animals and humans by direct contact to the lesions or bodily fluids. Monkeypox virus can be transmitted from one person to another through contact with infectious lesion material or fluid on the skin, in the mouth or on the genitals; this includes touching, close contact and during sex. It may also spread by means of respiratory droplets from talking, coughing or sneezing. The virus then enters the body through broken skin, or mucosal surfaces such as the mouth, respiratory tract, or genitals. The disease has also been reported in a wide range of other animals, including monkeys, anteaters, hedgehogs, prairie dogs, squirrels, and shrews.

Dormancy Period: Up to 24 weeks after initial symptoms.

Human malaria is caused by single-celled microorganisms of the Plasmodium group. It is spread exclusively through bites of infected female Anopheles mosquitoes. The mosquito bite introduces the parasites from the mosquito’s saliva into a person’s blood. The parasites travel to the liver, where they mature and reproduce.

Some malaria parasite species can remain dormant (inactive) in the liver for months or years after the initial infection. Later, after returning from an area with malaria, these parasites can then leave the liver and infect red blood cells and cause another episode of illness.

Symptoms of malaria can recur after varying symptom-free periods. Depending upon the cause, recurrence can be classified as either recrudescence, relapse, or reinfection. Recrudescence is when symptoms return after a symptom-free period due to failure to remove blood-stage parasites by adequate treatment. Relapse is when symptoms reappear after the parasites have been eliminated from the blood but have persisted as dormant hypnozoites in liver cells. 

Dormancy Period: 1 to 8 years,

The larvae develop into adult worms over the course of a year, during which time the patient  can be asymptomatic, and reach sexual maturity in the afferent lymphatic vessels. The worms can live for approximately 6–8 years and, during their lifetime, produce millions of microfilariae (immature larvae) that circulate in the blood. After mating, the adult female worm can produce thousands of microfilariae that migrate into the bloodstream. A mosquito vector can bite the infected human host, ingest the microfilariae, and thus repeat the lifecycle. They migrate between the deep and the peripheral, circulation exhibiting unique diurnal periodicity. During the day, they are present in the deep veins, and during the night, they migrate to the peripheral circulation.

Affects over 120 million people, primarily in Central Africa and the Nile delta, South and Central America, the tropical regions of Asia including southern China, and the Pacific islands and Indonesia.

Dormancy period: 2-4 weeks.

Leptospirosis is a blood infection caused by the bacteria Leptospira that can infect humans, dogs, rodents and many other wild and domesticated animals. Signs and symptoms can range from none to mild (headaches, muscle pains, and fevers) to severe (bleeding in the lungs or meningitis). Weil’s disease, the acute, severe form of leptospirosis, causes the infected individual to become jaundiced (skin and eyes become yellow), develop kidney failure, and bleed. Bleeding from the lungs associated with leptospirosis is known as severe pulmonary haemorrhage syndrome.

Leptospirosis is one of the most important worldwide zoonosis (jumps from animal to human) and is a major public health issue in many countries. The disease is caused by spirochetes from the genus Leptospira and is transmitted by contact of abraded skin or mucous membranes with contaminated rodent urine, water, or soil. Leptospirosis can cause severe multiple organ failure with a mortality rate as high as 50%. 

Dormancy Period: Weeks to months.

Leishmaniasis is a wide array of clinical manifestations caused by protozoal parasites of the Trypanosomatida genus Leishmania. It is generally spread through the bite of phlebotomine sandflies, Phlebotomus and Lutzomyia, and occurs most frequently in the tropics and sub-tropics of Africa, Asia, the Americas, and southern Europe. The disease can present in three main ways: cutaneous, mucocutaneous, or visceral. The cutaneous form presents with skin ulcers, while the mucocutaneous form presents with ulcers of the skin, mouth, and nose. The visceral form starts with skin ulcers and later presents with fever, low red blood cell count, and enlarged spleen and liver.

Some infected persons are asymptomatic, particularly in settings where cyclosporiasis is endemic. Among symptomatic persons, the incubation period averages one week (ranging as soon as 2 days – 2 weeks or more)

Dormancy period: Up to the lifetime of the patient.

Gastric disorders due to infection begin with gastritis, inflammation of the stomach lining. When infection is persistent the prolonged inflammation will become chronic gastritis. Initially this will be non-atrophic gastritis, but damage caused to the stomach lining can bring about the change to atrophic gastritis, and the development of ulcers both within the stomach itself or in the duodenum, the nearest part of the intestine.

Helicobacter pylori is a class 1 carcinogen, and potential cancers include gastric mucosa-associated lymphoid tissue (MALT) lymphomas and gastric cancer. Infection with H. pylori is responsible for around 89 per cent of all gastric cancers and is linked to the development of 5.5 per cent of all cases of cancer worldwide. H. pylori is the only bacterium known to cause cancer. Most people infected with H. pylori never experience any symptoms or complications, but will have a 10% to 20% risk of developing peptic ulcers or a 0.5% to 2% risk of stomach cancer. It was estimated that about two-thirds of the world’s population were infected with H. pylori, being more common in developing countries.

Dormancy period: Up to 8 weeks

Hantaviruses are a family of viruses spread mainly by rodents by inhalation. They can cause serious illness or death in people. Most hantaviruses are not transmitted from person to person. The spectrum of disease associated with hantavirus infection include hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS) also known as hantavirus cardiopulmonary syndrome (HCPS). The virus can cause severe infections of the lungs (with cough and shortness of breath) or kidneys (with abdominal pain, and sometimes kidney failure). Symptoms of hantavirus typically develop 1-8 weeks after exposure to rodents or rodent droppings and may be non-specific, including fever, fatigue, muscle aches, nausea, and cough.

Dormancy period: 2 days, however some people are asymptomatic and can shed virus for weeks.

Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus (IAV) which primarily affects birds but can sometimes affect mammals including humans. Rarely, humans can become infected by the avian flu if they are in close contact with infected birds. An avian influenza virus can acquire characteristics, such as the ability to infect humans, from a different virus strain. Influenza A virus, that has been modified with mRNA, can infect humans. Many people remain asymptomatic but can shed virus for weeks.

Dormancy period: Up to 10 days for poisonous strains. Beneficial strains persist for life.

Most E. coli strains are harmless, but some serotypes such as EPEC, and ETEC are pathogenic and can cause serious food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls.

E. coli belongs to a group of bacteria informally known as coliforms that are found in the gastrointestinal tract of warm-blooded animals. E. coli normally colonizes an infant’s gastrointestinal tract within 40 hours of birth, arriving with food or water or from the individuals handling the child. In the bowel, E. coli adheres to the mucus of the large intestine. It is the primary facultative anaerobe of the human gastrointestinal tract. (Facultative anaerobes are organisms that can grow in either the presence or absence of oxygen.) As long as these bacteria do not acquire genetic elements encoding for virulence factors, they remain benign commensals.

The incubation period is usually 3–4 days after the exposure, but may be as short as 1 day or as long as 10 days.

Dormancy period: 2 days to 3 weeks. The patient can continue to be contagious for several months after recovery.

Ebola, also known as Ebola virus disease (EVD) and Ebola hemorrhagic fever (EHF), is a viral hemorrhagic fever in humans and other primates, caused by ebolaviruses. Symptoms typically start anywhere between two days and three weeks after infection. The first symptoms are usually fever, sore throat, muscle pain, and headaches. These are usually followed by vomiting, diarrhea, rash and decreased liver and kidney function, at which point some people begin to bleed both internally and externally. It kills between 25% and 90% of those infected – about 50% on average. Death is often due to shock from fluid loss, and typically occurs between six and 16 days after the first symptoms appear. Early treatment of symptoms increases the survival rate considerably compared to late start.

Dormancy period: Up to 14 days. Up to 80% are asymptomatic

Dengue fever is an illness you can get from the bite of a mosquito carrying one of four types of Dengue. Dengue isn’t contagious from person to person except when passed from a pregnant person to their child. Symptoms are usually mild with first infection, but repeated infections with a different version of dengue, the risk of severe complications increases. Dengue fever symptoms start to appear four to 10 days after a mosquito bite and can last three to seven days. About 1 in 20 people sick with dengue will develop severe dengue after their initial symptoms begin to fade. Do not take aspirin or ibuprofen. Some people remain asymptomatic but can still carry the parasite.

Typically, people infected with dengue virus are asymptomatic (80%) or have only mild symptoms such as an uncomplicated fever. Others have more severe illness (5%), and in a small proportion it is life-threatening. The incubation period (time between exposure and onset of symptoms) ranges from 3 to 14 days, but most often it is 4 to 7 days.

Dormancy period: Symptoms start 12 hours to 5 days after exposure

Cholera is a severe infection of the small intestine by some strains of the bacterium Vibrio cholerae, transmitted through the ingestion of contaminated food or water. It takes between 12 hours and 5 days for a person to show symptoms. Cholera can cause very bad diarrhea and dehydration that can kill within hours if left untreated. Raw fish and foods area common source of this disease. Most of those infected have no or mild symptoms.

The primary symptoms of cholera are profuse diarrhea and vomiting of clear fluid. These symptoms usually start suddenly, half a day to five days after ingestion of the bacteria. The diarrhea is frequently described as “rice water” in nature and may have a fishy odor. An untreated person with cholera may produce 10 to 20 litres (3 to 5 US gal) of diarrhea a day. Severe cholera, without treatment, kills about half of affected individuals. If the severe diarrhea is not treated, it can result in life-threatening dehydration and electrolyte imbalances. Estimates of the ratio of asymptomatic to symptomatic infections have ranged from 3 to 100. 

Dormancy period: Up to 12 days, some people are asymptomatic but can remain infected for a a year or longer.

Chikungunya is a disease transmitted to humans by mosquitoes in Africa, Asia, and the Americas. You can’t get it from another person, but mosquitoes do get it from biting a person who is infected. Most people don’t die from it. Chikungunya fever typically lasts from five to seven days and frequently causes severe and often incapacitating joint pain which sometimes persists for much longer periods.These typically occur two to twelve days after exposure. There is no modern medicine treatment however traditional cures are abundant. Approximately 3%-28% of people infected with chikungunya virus will remain asymptomatic.

Other symptoms may include headache, muscle pain, joint swelling, and a rash. Symptoms usually improve within a week; however, occasionally the joint pain may last for months or years. The risk of death is around 1 in 1,000. The very young, old, and those with other health problems are at risk of more severe disease. 

Dormancy period: Up to 6 weeks, plus lifetime negative damages.

After exposure to Brucella bacteria, humans generally have a two- to four-week latency period before exhibiting symptoms, which include acute undulating fever (>90% of all cases), headache, arthralgia (>50%), night sweats, fatigue, and anorexia. Later complications may include arthritis or epididymo-orchitis, spondylitis, neurobrucellosis, liver abscess formation, and endocarditis, the latter potentially fatal. The skeletal system is affected in 20–60% of cases, including arthritis (hip, knee, and ankle), spondylitis, osteomyelitis, and sacroiliitis (most common). Lumbar vertebrae can be affected showing the classical radiological sign of vertebral erosion.

Neurological symptoms include meningitis, encephalitis, radiculopathy, peripheral neuropathy, intracerebral abscesses, and acute or chronic neck rigidity (<50%), and the cerebrospinal fluid can show lymphocytic pleocytosis, low sugar, increased protein, positive bacterial culture (<50%), and agglutination (positive in >95%). Pulmonary infection can be from inhalation or hematogenous sources, and can cause any chest syndrome. Rarely is Brucella isolated from sputum.

Avian influenza, also known as avian flu or bird flu, is a disease caused by the influenza A virus (IAV) which primarily affects birds but can sometimes affect mammals including humans. Rarely, humans can become infected by the avian flu if they are in close contact with infected birds.
