Cholera is an intestinal bacterial disease spread through contaminated water. It originated in the Ganges Delta in 1817.
Treatment of cholera consists primarily of administrating an oral rehydration solution, while prevention consists of drinking boiled, bottled, or chemically treated water.
In 1866, a cholera epidemic occurred in East London because of the fecal waste of one toilet emptying into the River Lea.
In 2010, cholera broke out in Haiti after a catastrophic earthquake.
In literature, cholera is depicted by Thomas Mann in Death in Venice and by Gabriel Garcia Márquez in Love in the Time of Cholera.
