How effective is oral rehydration therapy for rotavirus infection?

Rotavirus can cause repeated watery stools and vomiting, with infants and young children especially vulnerable to fluid loss. Oral rehydration solution combines water with electrolytes and glucose in a formulation that supports absorption through the intestine. It does not stop rotavirus or replace an examination when dehydration is advanced. Improvement in alertness, drinking and urination are reassuring signs, but continue monitoring.

Prepare the solution exactly according to the packet instructions, using the stated amount of safe water. Offer small sips or spoonfuls often; if vomiting occurs, restart slowly after a short pause. Continue breast milk or the child’s usual suitable feeds. Do not dilute the solution or add extra sugar or salt. Keep a record of drinking and wet nappies, and read more in Oral Rehydration Therapy.

Seek urgent assessment if a child is difficult to wake, unusually floppy, confused, unable to drink, vomiting every attempt, or passing very little urine. A sunken appearance around the eyes, a dry mouth, cold hands or worsening weakness also warrants prompt medical advice. Blood in stool, severe abdominal swelling or breathing difficulty requires urgent care. Further context is available in Rotavirus Infection.

Ask how much fluid your child needs, how to judge wet nappies or urine, and whether any current medicine should be paused. Ask when feeding can return to normal and which dehydration signs mean you should go straight to emergency care.
