Abstract
This study analyzes the epidemiological characteristics of clustered outbreaks of school infectious diseases in Liwan District, Guangzhou City, from 2016 to 2021. Surveillance data were collected on outbreak occurrences, affected population demographics, disease types, and temporal distribution. Results indicate that outbreaks primarily involved respiratory and gastrointestinal infections, with hand-foot-mouth disease and influenza being the most frequent. The majority of cases occurred among children aged 3 to 12 years, with a higher incidence in kindergarten and primary school settings. Seasonal peaks were observed in spring and autumn. Factors contributing to outbreaks included close contact environments, insufficient hygiene practices, and delayed reporting. The findings emphasize the need for strengthened school-based surveillance, timely intervention, and health education to prevent and control infectious disease clusters in educational settings.
