Rotavirus is the most important pathogen responsible for acute diarrhea in infants and young children. The incidence of rotavirus infection was studied in 156 children less than six years of age who were suffering from acute gastroenteritis, between February 22, 2006 and February 21, 2007 in Mashhad. Rotavirus antigen was detected by latex agglutination test (Rotascreen) in 28.8% of the stool samples examined. The frequency of rotavirus infection was significantly higher among patients under 24 months of age (69%) than among children two years old or more (31%). The peak of incidence was in the winter. This study revealed that rotavirus is an important etiological agent of acute gastroenteritis among children in Mashhad.
