When is oral rehydration therapy recommended for cholera?

Cholera can cause sudden, large-volume watery diarrhoea and rapid loss of water and electrolytes. An oral rehydration solution contains water and carefully balanced salts and glucose to help the intestine absorb fluid. It treats dehydration; it does not remove the infection or replace medical evaluation. A person who is severely dehydrated, very weak, confused, unable to drink, or vomiting repeatedly may need fluids through a vein and close monitoring.

Start a correctly prepared oral rehydration solution as soon as possible if the person is awake and can swallow. Follow the packet instructions exactly, using safe water and the stated volume; do not make it stronger or weaker. Offer frequent small sips, and continue after each loose stool. Keep the person under observation and arrange urgent medical assessment, especially for a child, older adult, or anyone with another serious illness. Avoid relying on very sugary drinks alone.

Go to urgent care immediately for confusion, fainting, inability to drink, very little urine, cold or clammy skin, severe weakness, or persistent vomiting. Cholera can worsen quickly, so do not wait for diarrhoea to settle before seeking help. Follow local infection-control advice and tell the care team about profuse watery diarrhoea or possible exposure.

Ask how severe the dehydration is, whether intravenous fluid or antibiotics are needed, how long to continue the solution, and which symptoms should trigger immediate return. Ask how to protect household members from contaminated water or food.
