Cholera is an infectious disease caused by the bacterium Vibrio cholerae, which primarily spreads through contaminated water and food. It leads to severe diarrhea and dehydration, which can be life-threatening if not treated promptly. Cholera outbreaks often occur in areas with poor sanitation and limited access to clean drinking water. Preventing cholera involves improving water quality, sanitation, and hygiene practices. Vaccines are available and can help reduce the risk of infection in high-risk areas. Public health measures, such as educating communities about safe food and water practices, are essential in controlling and preventing cholera outbreaks.
