Vibrio cholerae is a type of bacteria that causes cholera, a severe diarrheal disease. It is typically found in contaminated water or food, especially in areas with poor sanitation. When ingested, the bacteria can produce toxins that lead to rapid fluid loss, resulting in dehydration and potentially life-threatening complications. Cholera outbreaks often occur in regions affected by natural disasters or where access to clean water is limited. Preventive measures include improving water quality, promoting good hygiene practices, and ensuring proper sanitation. Vaccines are also available to help protect against Vibrio cholerae infections in high-risk areas.
