Trends in Norovirus Distribution among the Children of Childcare Center

Le résumé fourni par la source

Noroviruses are pathogens as being the leading cause of acute gastroenteritis (AGE) across all age groups, especially among vulnerable population, less than 5 years old.This study examined a total of 994 specimens collected from 58 cases of the kindergartens populations in Gyeonggi-Do from 2019 to 2021 to estimate the incidence of viral enteropathogens and analyze molecular genetic characteristics.Noroviruses were the most common viral pathogen causing among these population with acute gastroenteritis (n=55, 94.8% of cases tested).We found that norovirus outbreak of kindergarten exhibited a seasonality from the winter to summer with a peak in April.In particular, genotype GII noroviruses were particularly prevalent in the kindergarten population, with GII-4/2012 being highly detected in 119 specimens, followed by GII-3 and GII-2 as pathogenic agents causing AGE.Samples from workers or environment (toilet, doorknob, toy) were positive for a same genetic norovirus (GII-4/2012).Our results suggest that special attention needs to be paid to any possible contamination with noroviruses.Furthermore, a regular monitoring system can help prevent the norovirus outbreaks.
