means An acute bacterial infection of the small intestine, spread through contaminated water, that causes violent watery diarrhea and can kill through dehydration within hours if untreated.

from From Greek cholera, tied to cholē, 'bile' — ancient physicians blamed the disease on an excess of yellow or black bile under humoral theory, the idea that the body's four fluids had gone catastrophically out of balance. The Greek term may itself relate to cholē's cousin kholos, 'anger,' bile being the fluid of temper as well as digestion. The name stuck long after the bile theory died, outliving the physiology that invented it — by the 19th century the word belonged to the bacterium Vibrio cholerae and to the water-borne pandemics that forced cities like London to finally rebuild their sewers.
