摘　　要：目的分析2008—2023年河南省手足口病季节分布特征,为制定更加科学、有效的手足口病防控措施提供依据。方法通过中国疾病预防控制中心传染病报告信息管理系统选取2008—2023年河南省手足口病报告信息,分月汇总病例数,分别采用集中度法、季节指数法和圆形分布法等3种方法分析河南省手足口病季节分布特征。结果2008—2023年河南省共报告手足口病1106708例,年均发病率为72.79/10万,集中度(M)为0.418,各年度M值的取值范围在0.281~0.787之间,提示发病具有一定的季节性;4—7月的季节指数(C)>100%,其中5月份数值最高(256.795%),显示4—7月为手足口病的流行季节;圆形分布法结果显示,发病高峰日为7月1日,流行高峰期为4月20日—9月16日(Z=191100.689,P<0.001)。结论河南省手足口病具有一定的季节性特征,应在高发季节来临前尽早落实各项防控措施,降低聚集性疫情及暴发疫情的发生风险。Objective To analyze the seasonal distribution of hand-foot-and-mouth disease(HFMD)in Henan Province from2008 to 2023 and provide evidence-based insights for the prevention and control of HFMD.Methods Reported HFMD case data in Henan from 2008 to 2023 were extracted through the National Notifiable Infections Diseases Reporting System of Chinese Center for Disease Control and Prevention.Monthly case counts were analyzed using concentration method,seasonal index,and circular distribution method to determine the seasonal distribution characteristics.Results A total of 1106708 HFMD cases were reported in Henan,with an average annual incidence of 72.79/105.The concentration degree(M)was 0.418.The annual M ranged from 0.281-0.787,indicating a seasonal distribution pattern.The seasonal index(C)from April to July was greater than100%,peaking in May at 256.795%,indicating the epidemic season of April to July.Circular distribution analysis identified July1st as the peak date for incidence,with a peak period from April 20 to September 16th(Z=191100.689,P<0.001).Conclusions HFMD exhibits distinct seasonal distribution characteristics in Henan.It is recommended that preventive measures should be implemented early in high-incidence season to mitigate the peaks of outbreaks.
