Rotavirus

Overview

Rotavirus is a very contagious virus that causes diarrhea. Before the development of a vaccine, most children had been infected with the virus at least once by age 5.

Although rotavirus infections are unpleasant, you can usually treat this infection at home with extra fluids to prevent dehydration. Occasionally, severe dehydration requires receiving fluids through a vein (intravenously) in the hospital.

Good hygiene, such as washing your hands regularly, is important. But vaccination is the best way to prevent rotavirus infection.
