Cholera is a severe diarrheal infection caused by a specific bacterium that colonizes the intestine. Transmission typically occurs through the ingestion of contaminated food or water, making sanitation and clean water access crucial for prevention. The infection causes the rapid loss of fluids and electrolytes, resulting in profuse, watery diarrhea. Severe cases lead to rapid dehydration and electrolyte imbalance, which can quickly become life-threatening. Treatment focuses primarily on rehydration and electrolyte replacement to stabilize the patient and mitigate the severity of the systemic shock caused by fluid loss.
