摘　　要：目的分析2017—2022年江阴市手足口病(hand-foot-mouth disease,HMFD)聚集性疫情的流行特征及病原学结果,为今后手足口病防控工作提供科学依据。方法采用描述性流行病学方法进行分析,描述疫情的流行特征及发病规律,率的比较采用χ^(2)检验,连续性变量的相关分析采用Spearman检验。结果2017—2022年江阴市共报告手足口病聚集性疫情116起,每年4—6月和11月为疫情高峰,每月手足口病聚集性疫情起数与当月报告例数呈正相关(r=0.801,P<0.001);不同街道/镇手足口病聚集性疫情起数,差异有统计学意义(χ^(2)=53.255,P<0.001);不同场所手足口病聚集性疫情起数,差异无统计学意义(Fisher=14.689,P=0.141);不同场所手足口病聚集性疫情报告病例数,差异有统计学意义(Fisher=32.367,P<0.001);256例手足口病病例病原体阳性率为65.63%,手足口病聚集性疫情中不同型别病原体的构成情况,差异有统计学意义(Fisher=0,P<0.001)。结论2017—2022年江阴市手足口病聚集性疫情于4—6月及11月多发于托幼机构,应加强重点场所消毒和防控,防止疫情暴发流行。Objective To analyze the epidemiological characteristic and etiologic results of the outbreak in clusters of hand-foot-mouth disease(HFMD)in Jiangyin City from 2017 to 2022,and to provide a scientific basis for the prevention and control of HFMD in the future.Method A descriptive epidemiological method was used for analysis,describing the epidemiological characteristic and incidence patterns of the epidemic.The comparison of rates was performed using the Chi-square test,and the correlation analysis of continuous variables was performed using the Spearman test.Results A total of 116 cases of the outbreak in clusters of HFMD were reported in Jiangyin City from 2017 to 2022.The incidence peaks of the epidemic occurred from April to June and November each year.The number of the outbreak in clusters of HFMD per month was positively correlated with the number of reported cases in that month(r=0.801,P<0.001).The number of the outbreak in clusters of HFMD in different streets/towns had a statistically significant difference(χ^(2)=53.255,P<0.001).The number of the outbreak in clusters of HFMD in different sites had no statistically significant difference(Fisher=14.689,P=0.141).The number of reported cases of the outbreak in clusters of HFMD in different sites had a statistically significant difference(Fisher=32.367,P<0.001).The pathogen positivity rate of 256 cases of HFMD was 65.63%.The composition of different types of pathogens in the outbreak in clusters of HFMD showed a statistically significant differences(Fisher=0,P<0.001).Conclusion The outbreak in clusters of HFMD in Jiangyin City from 2017 to 2022 occurr mostly in childcare settings from April to June and in November.Disinfection,prevention and control of key sites should be strengthened to prevent outbreaks and epidemics.
