Cholera is a serious bacterial infection that primarily affects the intestines, leading to severe diarrhea and dehydration. It is caused by the bacterium Vibrio cholerae, which is often found in contaminated water or food. People can become infected when they consume these contaminated sources, especially in areas with poor sanitation. The symptoms of cholera can appear suddenly and may include watery diarrhea, vomiting, and leg cramps. If not treated quickly, cholera can be life-threatening. Fortunately, it can be prevented through proper hygiene, access to clean drinking water, and vaccination in high-risk areas.
