Clinical Significance

Rotavirus infection is the major cause of gastroenteritis in children from six months to two years. Infection occurs in both sporadic and epidemic forms and is responsible for approximately half the cases of diarrhea in infants that require hospitalization worldwide. The peak of rotavirus disease in temperate climates occurs during the cooler months of the year. Rotavirus has also emerged as a cause of enteritis in adults, particularly in elderly immunosuppressed patients.
