Symptoms and causes Viruses are the most common cause, although bacteria and parasites can also be responsible. Children may develop watery diarrhea, vomiting, fever, reduced appetite and abdominal cramps.
Preventing dehydration Offer oral rehydration solution in small, frequent amounts. If vomiting occurs, pause briefly and restart with tiny sips. Continue breastfeeding. Once tolerated, return to normal age-appropriate food rather than keeping the child on a prolonged restrictive diet.
Medicines Antibiotics are not routinely needed because most cases are viral. Anti-diarrheal medicines can be unsafe in young children and should not be given without medical advice. Fever or pain medicine should be dosed according to age and weight.
Hygiene Frequent handwashing, separate towels and careful cleaning of contaminated surfaces help reduce spread. Children should remain away from school or nursery according to local infection-control guidance.
Urgent warning signs Seek urgent care for severe dehydration, green or bloody vomit, blood in stool, severe localized abdominal pain, a very sleepy child, rapid breathing, persistent vomiting, no urine for many hours or symptoms in a young infant.
