Overview
Choleria is a severe bacterial gastrointestinal, diarrheal disease. In its most severe forms, cholera is one of the most rapidly fatal illnesses known. A healthy person may become hypotensive within an hour of the onset of symptoms and may die within 2-3 hours if no treatment is provided. More commonly, the disease progresses from the first liquid stool to shock in 4-12 hours, with death following in 18 hours to several days without rehydration treatment.[1][2]
Epidemiology and demographics
False report of cholera
A persistent myth states that 90,000 people died in Chicago of cholera and typhoid fever in 1885. This story has no factual basis. In 1885 there was a torrential rainstorm that flushed the Chicago river and its attendant pollutants into Lake Michigan far enough that the city's water supply was contaminated. Fortunately, cholera was not present in the city and this is not known to have caused any deaths. It did, however, cause the city to become more serious about their sewage treatment.
