摘　　要：目的 分析福建省登革热的流行特征与时空聚集性特征,为登革热防控提供科学依据。方法 运用描述流行病学、空间自相关分析和时空扫描法对2011-2023年福建省登革热病例进行分析。结果 2011-2023年,福建省共报告登革热病例3586例,其中本地病例2360例,境外输入病例1134例,境内输入病例92例。全省10个地市均有病例报告,88个县区中有81个县区报告了病例。输入病例全年均有,但本地病例的发生具有明显的季节性,本地病例与境内输入主要集中在8-10月份,境外输入以6-10月居多。境外输入病例来源国以东南亚国家为主,但有从东南亚国家向南亚、非洲、美洲等地区蔓延的趋势。福建省登革热分布存在时空聚集性(Moran’s I值介于0.14~0.66,P<0.05),高-高聚集区主要分布在福州、泉州、莆田,时空扫描共探测到3个聚集区,包含1个主要聚集区及2个次要聚集区,主要分布在福州、泉州、莆田、漳州与厦门,聚集时间为7月底至10月份。结论 福建省登革热分布存在明显的时空聚集性,聚集时间为7月底至10月份,高发地区为福州、泉州、莆田、漳州与厦门。对于高聚集区,可在每年本地病例出现之前,提前开展爱国卫生运动、防蚊灭蚊、加强疫情监测、医务人员培训等相关措施,减少因输入造成的登革热本地传播。The epidemiological and spatiotemporal clustering characteristics of dengue fever in Fujian Province were analyzed,to provide a scientific basis for dengue fever prevention and control.Descriptive epidemiology,spatial autocorrelation analysis,and spatiotemporal scanning were used to analyze dengue fever cases in Fujian Province from 2011 to 2023.In this period,a total of 3586 cases of dengue fever were reported in Fujian Province,including 2360 local cases,1134 imported cases from abroad,and 92 imported cases from China.Cases were reported in ten prefectures and cities of the province,and 81 out of 88 counties reported cases.Imported cases were reported throughout the year in Fujian Province,but the occurrence of local cases showed clear seasonality.Local cases and domestic imports were concentrated in August to October,whereas overseas imports occurred primarily from June to October.The imported cases were mainly from Southeast Asian countries,but a trend of spreading from Southeast Asian countries to South Asia,Africa,the Americas,and other regions,was observed.Spatio-temporal clustering of dengue fever was found in Fujian Province(Moran’s I value 0.14-0.66,P<0.05),and the high-high aggregation areas were distributed primarily in Fuzhou,Quanzhou,and Putian.Spatio-temporal scanning detected three aggregation areas:one main and two secondary.The aggregation time was from the end of July to October,and the distribution was primarily in Fuzhou,Quanzhou,Putian,Zhangzhou,and Xiamen.The distribution of dengue fever in Fujian Province showed clear spatial and temporal clustering from the end of July to October,and the distribution was primarily in Fuzhou,Quanzhou,Putian,Zhangzhou,and Xiamen.For high concentration areas,national health campaigns,mosquito prevention and control,epidemic surveillance,medical personnel training,and other relevant measures could be carried out in advance before local cases appear every year.Reduce local transmission of dengue fever due to importation.
