Cholera is a bacterial infection caused by the bacterium Vibrio cholerae. It primarily affects the small intestine and leads to severe watery diarrhoea and dehydration. Cholera is typically transmitted through contaminated water or food, often in areas with poor sanitation and inadequate access to clean drinking water.  Symptoms of cholera can range from mild to severe and may include diarrhoea, vomiting, rapid heart rate, low blood pressure, and muscle cramps. If left untreated, cholera can be life-threatening due to severe dehydration. Treatment for cholera focuses on rehydration and addressing electrolyte imbalances. Oral rehydration solutions (ORS) are commonly used to replace lost fluids and electrolytes. In severe cases, intravenous fluids may be necessary. Antibiotics can also be prescribed to reduce the duration and severity of symptoms. Preventing cholera involves improving access to clean water and sanitation facilities, promoting good hygiene practices such as handwashing, and ensuring proper food safety measures. Vaccines are available for prevention.
