Abstract

An outbreak of acute gastroenteritis was reported from a kindergarten on January 5, 2018 and investigation was conducted. A case was defined as a kindergartener presented with vomiting or diarrhea twice a day between January 1 and January 5, 2018. All kindergarteners were interviewed to identify the factor associated with case development. Fifteen (31.3%) children of a total of 48 were identified as cases, and four were confirmed to be Group II, Norovirus positive. In our study, based on the pattern of epidemic curve and different attack rate by classroom in a kindergarten, Norovirus was likely transmitted from human to human.
