Cholera is an infection of the small intestine caused by the bacterium Vibrio cholerae. The bacteria produce a toxin that triggers the symptoms of cholera. Common symptoms include watery diarrhoea which, if not addressed promptly, can progress to dehydration and, in severe cases, may be fatal. Early and proper treatment is crucial. Cholera typically occurs in countries with limited sanitation and is often contracted through contaminated food or water. Symptoms appear within 12 hours to 5 days after ingesting the contaminated substance.
