Rotavirus
Rotavirus is a very common and highly contagious stomach bug that primarily affects babies and young children. It causes severe watery diarrhea, vomiting, fever, and abdominal pain. While unpleasant, most children recover fully with proper care.
Common symptoms
- Severe watery diarrhea
- Vomiting
- Fever
- Abdominal pain
- Dehydration (e.g., dry mouth, decreased urination, lethargy)
- Irritability
Cause
Rotavirus is caused by a virus.
How common is it?
Before vaccination became routine, rotavirus caused nearly all severe diarrheal disease in U.S. infants and young children. Thanks to vaccination programs started in 2006, rotavirus hospitalizations have declined by more than 80%. However, unvaccinated children remain at significant risk.
Treatment
There's no specific medicine to cure rotavirus, so treatment focuses on preventing dehydration. Offer frequent small sips of oral rehydration solution (ORS) or clear fluids like water or diluted juice. Avoid sugary drinks and full-strength juices, as they can worsen diarrhea.
Prevention
The most effective way to prevent rotavirus is through vaccination, which is recommended for infants. Good handwashing with soap and water, especially after diaper changes and before eating, is also crucial to limit the spread of the virus.
