Abstract：Objective To understand the epidemiological features of aggregation epidemic events of infectious diseases in schools in Hongshan District of Wuhan City during 2010-2019, and to provide a basis for developing the effective prevention and control measures. Methods The characteristics of aggregation epidemic events of infectious diseases in schools in Hongshan District of Wuhan City during 2010-2019 were analyzed by using descriptive epidemiological methods. Results From 2010 to 2019, a total of 1,568 aggregation outbreaks of infectious diseases occurred in schools in Hongshan District of Wuhan City, with the incidence rate of 12.89%. Four public health emergencies were reported, all of which occurred in schools. From 2010 to 2019, the incidence rates of infectious diseases in aggregation epidemic events in schools among different years showed statistically significant differences (χ2trend=47.605, P<0.001), and the incidence rates increased year by year. The main kinds of infectious diseases in aggregation epidemic events were influenza-like illness cases, hand-foot-mouth disease, herpangina and chickenpox, accounting for 90.56% of total diseases. The incidence of infectious diseases occurred in April-June and December-January of next year. The epidemic events of infectious diseases mainly occurred in nurseries and primary schools, accounting for 93.69% of total outbreaks. The epidemic events in nurseries were mainly caused by hand-foot-mouth disease and herpangina transmitted by the fecal-oral route, while those in primary and middle schools were mainly caused by influenza-like illness cases and varicella transmitted by the respiratory route. The attack rate of infectious diseases was found to be the highest in middle schools (22.82%), followed by primary schools (15.55%), universities (13.50%) and kindergartens (11.92%), showing statistically significant differences in the attack rates among different schools (χ2=71.701, P<0.001). Conclusion The aggregation epidemic events of infectious diseases in schools in Hongshan District of Wuhan City during 2010-2019 showed an upward trend. Infectious disease prevention and control in schools should be adapted to local conditions in future, and more appropriate comprehensive prevention and control measures based on the characteristics of different populations, different institutions and seasonality should be taken in time.
