Cholera is an acute diarrheal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. Every year, there are an estimated 3 to 5 million cholera cases and 100 000 to 120 000 deaths due to cholera. The short incubation period of 2 hours to 5 days, enhances the potentially explosive pattern of outbreaks.
Cholera is an extremely virulent disease. It affects both children and adults and can kill within hours. About 75% of people infected with Vibrio cholerae do not develop any symptoms, although the bacteria are present in their feces for 7–14 days after infection and are shed back into the environment, potentially infecting other people.
