Causes of Cholera

Contaminated Feces
In an epidemic, the source of the contamination is usually the feces of an infected person. Cholera can spread rapidly in areas with inadequate treatment of sewage and drinking water. Once Vibrio cholerae is ingested, the bacteria travel to the small intestine where it begins to multiply.
 
Vibrio cholerae then begins producing its toxin, which is the main cause of watery diarrhea, a characteristic symptom of infection. In order to develop cholera symptoms, however, a person would need to ingest a considerable amount of Vibrio cholerae.
