Abstract：Objective To understand the epidemiological characteristics of school influenza outbreaks in Chongming District, Shanghai City, so as to provide scientific evidence for the control and prevention of influenza in the future. Methods The relevant data of school influenza outbreaks reported from the Influenza Surveillance Information System of China from 2016 to 2021 were collected and analyzed by the descriptive epidemiological analysis method. Results From 2016 to 2021, a total of 9 school influenza outbreaks were reported in Chongming District, and 160 patients were involved, affecting 5 056 people, and the incidence rate was 3.16% (160/5 056). The outbreaks occurred mainly in January and December, and 8 outbreaks occurred mainly in primary schools. The main influenza viruses that caused influenza outbreaks were B/Victoria, followed by influenza A/H1N1 (2 outbreaks) and A/H3N2 (2 outbreaks). The duration of the epidemic was positively correlated with the days the CDC intervened (r=0.836, P=0.005). Conclusion The high-risk place for school influenza outbreaks in Chongming District are primary schools, which are prone to outbreaks in winter and spring, and early and effective prevention and control measures are the key to preventing school influenza outbreaks.
