Cholera is an acute diarrheal infection caused by consuming food or water contaminated with the Vibrio cholerae bacterium. Severe watery diarrhea and dehydration are the primary symptoms of the disease.
The disease is generally more common in developing countries where access to safe drinking water and sanitation infrastructure is inadequate. While cholera cases have been largely controlled in industrialized countries thanks to modern sewage and water treatment systems, it remains a serious health problem in regions such as Africa, Southeast Asia, and Haiti. Prevention is possible through access to clean water sources, good hand hygiene, and careful consumption of food and beverages in risky areas.
Common symptoms include severe diarrhea and dehydration; rarely, in particularly severe cases, shock and seizures may also occur. Severe dehydration can be fatal if not treated promptly. Therefore, early medical intervention is vital. Treatment methods include rehydration (with oral or intravenous fluids) and, in appropriate cases, antibiotics.
