Viral — Intestinal Infection
About Rotavirus
Rotavirus causes gastroenteritis and infects almost all young children by age 5. Rotavirus A causes more than 90% of human infections. Children can be infected more than once, but the first infection is usually the worst; older children and adults can also be infected.
Symptoms appear about 2–3 days after exposure. Children can spread the virus before and after they have diarrhoea. Rotavirus vaccines are very effective at preventing it.
