Abstract
There are limited reports on the etiology of multiple enteric viruses causing acute gastroenteritis (AGE) in North India. In the present study we have determined the prevalence of three enteric viruses, namely rotavirus, astrovirus (AstV) and adenovirus (AdV) in a total of 312 diarrheic children (P = .01). Increased duration of vomiting (≥3 days) was significantly (P = .04) associated with AdV infection (61.3%) as compared with AstV (30.76%) and rotavirus (26.31%). G1P[8] was detected throughout as the most prevalent rotavirus strain (10.5%). Unusual RV strains like G2P[6] and G2P[8] were also detected. Of note G3, G4, and G12 rotavirus were detected for the first time in Meerut. This is the first report that demonstrated the important contribution of multiple enteric viruses causing AGE in young children in this part of Uttar Pradesh (Meerut).
