Rotavirus (Rotavirus Infection)

Rotavirus Home

magnified rotavirus Rotavirus is the most common cause of severe diarrhea among children, resulting in the hospitalization of approximately 55,000 children each year in the United States and the death of over 600,000 children annually worldwide. The incubation period for rotavirus disease is approximately 2 days. The disease is characterized by vomiting and watery diarrhea for 3 - 8 days, and fever and abdominal pain occur frequently. Immunity after infection is incomplete, but repeat infections tend to be less severe than the original infection.

Unusual Rotavirus Season May Be due to Newly Introduced Vaccine NEW

CDC has issued an interim report describing marked changes in rotavirus activity in the ongoing 2007–08 U.S. rotavirus season. The report indicates that rotavirus activity started considerably later and was much less extensive compared with activity in previous years. These changes coincide with increasing use of rotavirus vaccine among infants.
