Here's a look at what you need to know about cholera, an acute diarrheal disease which kills thousands of people worldwide each year.
Facts: Approximately 200,000 cases are reported to the World Health Organization every year. However, the WHO believes the true number of cases annually is between 3-5 million, with 100,000 to 120,000 deaths.
Cholera is contracted by consuming food or water contaminated with the fecal bacteria Vibrio cholerae.
The symptoms are usually mild, but about 20% of cases include symptoms of watery diarrhea.
Dehydration from rapid loss of body fluids is the reason the disease can be so deadly within hours if the patient is not treated.
The disease's short incubation period of two hours to five days increases the likelihood of outbreaks.
80% of cholera cases can be treated and resolved with oral hydration salts.
There are two two-dose oral vaccines available, Dukoral and ShanChol, but it may take weeks for an individual to have full protection.
Cholera is rare in industrialized nations.
People who live in areas with poor or inadequate water treatment, sanitation, and hygiene practices are more likely to get the disease.
The world is currently experiencing its seventh cholera pandemic, which began in Indonesia in 1961.
