Causes of Cholera

Cholera is an infectious disease that causes severe watery diarrhea, which can lead to dehydration and even death if untreated. It is caused by eating food or drinking water contaminated with a bacterium called Vibrio cholerae. The cholera bacteria travel with their hosts, spreading worldwide as the crustaceans follow their food source — certain types of algae and plankton that grow explosively when water temperatures rise. Common sources of cholera  include: Municipal water supplies; Ice made from municipal water; Foods and drinks sold by street vendors and Vegetables grown with water containing human wastes.
