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. Cholera has been nicknamed the “blue death” because a person’s skin may turn bluish-gray from extreme loss of fluids.

Cholera continues to affect an estimated 3–5 million people worldwide and causes 28,800–130,000 deaths a year.
