Key result
Among hospitalized children with acute gastroenteritis in Seoul, Korea, norovirus was detected in 710 samples, with the GII genogroup being the most prevalent (96.2%, 683/710).
Observational
Norovirus GII is the predominant genogroup causing acute gastroenteritis in hospitalized children in Seoul, Korea.
Supports local norovirus GII surveillance in Seoul pediatric wards; leaves open generalizability beyond this single-center cohort.
The present study has determined the detection rate of norovirus (NoV) with acute gastroenteritis (AGE) in hospitalized children and describes the molecular epidemiology of NoV circulating in Seoul, Korea. Six hundred and eighty-three (9.8%) of samples were positive for NoV. Of these, the NoV GII genogroup was the most commonly found, with a prevalence of 96.2% (683 of 710). Only 27 samples were positive for the NoV GI genogroup. Ten kinds of GI genotype (GI/1, GI/2, GI/3, GI/4, GI/5, GI/6, GI/7, GI/9, GI/12, and GI/13) and eight kinds of GII genotype (GII/2, GII/3, GII/4, GII/8, GII/14, GII/15, GII/16, and GII/17) were identified in children with AGE during the years 2008-2011.

Park et al. (2012) conducted an observational in Acute gastroenteritis. Norovirus infection was evaluated on Detection rate and molecular epidemiology of norovirus. Among hospitalized children with acute gastroenteritis in Seoul, Korea, norovirus was detected in 710 samples, with the GII genogroup being the most prevalent (96.2%, 683/710).
