Background:
Rotaviruses a major group of viruses that cause severe gastroenteritis in young children worldwide. Many different viruses can cause gastroenteritis, including Noroviruses, Adenoviruses, Sapoviruses, and Astroviruses. Serum antibody studies show that most of the children are infected with Rotavirus at least once in their life by the age of 3. In the world, approximately 400-600 thousand children in poor countries die annually by Rotavirus-associated dehydration. Most of the deaths occur in these countries because of delay in treatment. Despite low death rates in industrialized countries, good hygiene and sanitation do not appear to reduce the prevalence or prevent the spread of Rotavirus.
