Cholera, sometimes known as Asiatic or epidemic cholera, is an infectious gastroenteritis caused by bacteria called Vibrio cholerae. Humans get this through eating food or drinking water contaminated with Vibrio cholerae from other cholera patients.
Cholera likely has its origins in and is endemic to the Indian subcontinent, with the River Ganges serving as a contamination reservoir. The disease spread by trade routes (land and sea) to Russia, then to Western Europe, and from Europe to North America. Cholera is now no longer considered a pressing health threat in Europe and North America due to filtering and chlorination of water supplies, but still heavily affects populations in developing countries.
