Objective To analyze the outbreak epidemic of norovirus infection in different types of schools in a city, and provide basis for formulating corresponding prevention and control measures. Methods Outbreak epidemic of norovirus infection reported by various schools in the "public health emergency management information system" of the city from January 1, 2014 to December 31, 2018 was collected, epidemiological analysis was conducted. Results A total of 41 norovirus outbreaks were reported in schools during 5 years, 2 444 cases were reported, with an incidence of 2.96%. Incidence of norovirus infection in schools was statistically different during 5 years (P<0.05). The number of norovirus outbreak epidemic was most in primary schools (25 cases, 60.97%); the highest incidence in colleges and universities was 5.10%, there was significant difference in the incidence of norovirus infection among different types of schools (P<0.05). The reporting interval of norovirus outbreak epidemic in schools was 4 days and duration of outbreak was 7 days during 5 years; there was significant difference in the reporting interval and duration of epidemic among different types of schools (all P<0.05); there was a positive correlation between reporting interval and duration of epidemic (r_s=0.73,P<0.01). Conclusion Primary schools are the places with high incidence of norovirus infection and outbreak in schools, prevention and control of norovirus infection and outbreak in colleges and universities needs to be strengthened urgently.
