Cholera theory

Cholera theory explains how the cholera bacterium, Vibrio cholerae, causes illness. It spreads mainly through contaminated water or food, often in areas with poor sanitation. When ingested, the bacteria invade the intestines and produce toxins that disrupt normal fluid absorption, leading to rapid, severe diarrhea and dehydration. If untreated, this can become life-threatening. Understanding this process highlights the importance of clean water, proper waste management, and hygiene practices in preventing cholera outbreaks and protecting public health.
