Abstract / Description
BackgroundUnderstanding temporal and epidemiological patterns of pediatric infectious diseases is essential for developing targeted prevention strategies. This study investigated long-term incidence trends and epidemiological characteristics of notifiable infectious diseases among children in Xuhui District, Shanghai, from 2015 to 2023.MethodsSurveillance data for children aged 0-17 years were obtained from the National Notifiable Disease Reporting System (NNDRS). Joinpoint regression was applied to identify temporal trends and significant inflection points. Age-specific distributions were analyzed and seasonal patterns were visualized using radar charts.ResultsFrom 2015 to 2023, a total of 27,940 pediatric cases involving 23 notifiable infectious diseases were reported, corresponding to an average annual incidence of 2,421.68 per 100,000 children. Joinpoint regression identified a significant inflection point in 2021. Overall incidence declined during 2015-2021 (APC = -11.71%, 95% CI: -30.10 to -1.50, P = 0.029) and increased sharply thereafter (APC = 141.05%, 95% CI: 34.40-244.50, P
