How effective is oral rehydration therapy for cholera?

Cholera can cause sudden, frequent watery diarrhoea, so the body loses fluid and electrolytes quickly. An oral rehydration solution contains a carefully balanced combination of water, salts and glucose. The intestine absorbs these together, helping move fluid back into the body even while diarrhoea continues.

This treatment corrects dehydration; it does not remove the infection or replace a clinician’s assessment. Severe fluid loss may require fluids through a vein, and some people need prescribed treatment for the infection. Avoid relying on plain water alone when losses are heavy, because it does not replace the salts being lost.

Use a commercially prepared oral rehydration solution and mix it exactly as the packet directs. Give small, frequent sips; if vomiting occurs, pause briefly and restart more slowly. Continue offering the solution after each watery stool, and keep breastfeeding or offering suitable food when tolerated.

Cholera is a medical emergency risk because dehydration can progress quickly. Arrange urgent medical care, take the rehydration solution with you, and follow local advice about hygiene and safe water to reduce spread.

Seek urgent help for confusion, unusual sleepiness, fainting, very little or no urine, a dry mouth with intense thirst, cold hands or feet, fast breathing, or inability to drink. A child, older adult, pregnant person, or anyone with a long-term illness may worsen quickly and should be assessed promptly.

Ask which oral rehydration product and amount are suitable, how to judge whether fluid replacement is working, whether testing or prescribed treatment is needed, and when intravenous fluids should be considered.
