Watery diarrhoea can be a sign of Cholera. It is capable of causing death if not treated immediately. The culprit is a bacterium called Vibrio cholera. It infects and spreads through drinking from the infected water source, shellfish, and contaminated food or eating with unwashed hands. The main symptom is severe diarrhoea with the consistency of rice-water stool and excruciating abdominal pain. Organ failure is from severe loss of fluid and electrolyte. It is diagnosed during an outbreak or individually through stool culture. Management of Cholera is to ensure the patient is not dehydrated. This is achieved with fluid and electrolyte IV infusion in addition to strict monitoring of the fluid balance. Antibiotic is the secondary role in the treatment.
