Rotavirus is causative agent of diarrhea resulting in mortality in children up to the age group of 5 years. The first infection occur between age group of 6-9 months. However, the need for screening of rotavirus is important to access the incidence of severe disease or effectiveness and its serotype distributions. To detect any new ideotype in re-assortment a continuos screening of existence genotype is required. Multiple assay now exist for measuring the serological response to Rotavirus infection. ELISA and RNA-PAGE are considered to be highly sensitive tool for screening of Rotavirus because its abilty to detect even at low concentration.
