Cholera is an infection of the small intestine caused by the cholera bacterium, which causes severe watery diarrhea and can lead to rapid dehydration. It is typically contracted by consuming food or water contaminated with the feces of an infected person. While cholera epidemics are currently occurring in parts of Asia, Africa, and Latin America, it is unlikely a person living in the United States would get cholera due to modern water and sewage treatment systems. Cholera can be fatal if not treated due to dehydration, but oral rehydration solutions can treat the dehydration and antibiotics can lessen the severity of symptoms.
