What to expect from oral rehydration therapy for rotavirus infection

Rotavirus infection often causes watery diarrhoea, vomiting, fever, and reduced appetite. Children can become dehydrated quickly because they may lose fluid and struggle to drink. Oral rehydration solution supplies water, salts, and glucose in a form that helps absorption. It does not eliminate rotavirus or act as an antibiotic; its purpose is to support hydration during recovery.

Offer the prepared solution in frequent small sips or spoonfuls, especially after loose stools or vomiting. If vomiting occurs, pause briefly and restart with smaller amounts. Mix sachets exactly as directed and discard solution according to the product instructions. Continue breastfeeding if applicable, and offer suitable foods when the child wants them. Do not dilute the solution with extra water or replace it with very sugary drinks.

Seek urgent care if a child is unusually sleepy, difficult to wake, confused, breathing abnormally, unable to drink, repeatedly vomiting, or passing very little urine. A dry mouth, no tears, sunken eyes, or worsening weakness also needs prompt assessment. Infants and children with ongoing losses should be assessed early because their condition can change quickly.

Ask how much solution to offer, how to judge urine and alertness, and when persistent diarrhoea or vomiting needs a review.
