What are the signs and symptoms of rotavirus infection?
Rotavirus infection usually starts with fever and vomiting, followed by diarrhea. The diarrhea can be mild to severe and generally lasts 3-9 days. Illness usually begins 3 days after exposure. Children with severe diarrhea can lose body fluids very quickly and may need to be hospitalized for special therapy to replace fluids and restore chemical balance.
