What is the etiological agent and the main manifestations of cholera?

Cholera is a bacterial disease caused by the Vibrio cholerae. The disease is transmitted by fecal-oral route and the major mode of transmission is ingestion of contaminated water or food. It is most prevalent in places that lack adequate sanitary conditions.

Inside the human gut the cholera vibrion releases toxins known as enterotoxins. The infection can cause intense diarrhea, vomiting, dehydration and even death in more severe cases.
