The distribution of norovirus (NoV) genogroup II in children < 5 years of age admitted to a south Indian hospital with diarrhea was investigated. Viral RNA extracted from 282 stool samples were screened for NoV GII and positive amplicons sequenced. Twenty-eight (9.9%) had NoV GII infection with a median age of 6 months, with more severe episodes of diarrhea among infected (median Vesikari score 13, interquartile range [IQR] 10–15) than children without infection (median score 10, IQR 8–13, = 0.002). The study documents NoV GII infections as an important cause of gastroenteritis and the genetic diversity of circulating strains.
