摘　　要：目的分析广州市2019—2023年登革热疫情流行病学特征,为登革热防控提供科学依据。方法通过中国疾病预防控制信息系统收集2019—2023年报告地为广东省广州市的登革热病例资料,采用横断面分析方法描述三间分布,并分析其流行病学特征。结果2019—2023年,广州市累计报告登革热病例3518例,其中本地3101例(88.15%),输入417例(11.85%),年均发病率在0.09/10万~17.59/10万之间。各月份均有输入性登革热病例报告,其中5—11月为报告高峰(374例,占89.69%)。本地病例最早出现在5月,末例病例报告时间为12月,发病高峰集中在8—11月(2960例,占95.45%)。全市11个区均有病例报告,报告数前3位的为白云区、越秀区和荔湾区。男性病例占53.52%,女性占46.48%。年龄主要集中于20~<60岁(2547例,占72.40%)。职业居前3位的分别为商业服务(784例)、家务及待业(738例)和离退人员(596例)。本地病例发病至诊断时间平均为4.06 d,输入病例为4.60 d。境外输入病例主要来自东南亚地区占88.10%(311/353),其中柬埔寨输入最多。省外输入病例主要来自云南省,省内其他地区输入病例主要来自佛山市。结论近年来广州市登革热发病率保持在较高水平,具有明显的输入性和季节性,相关部门应关注重点防控人群,采取有效措施降低蚊媒密度,严防疫情扩散。Objective To analyze the epidemiological characteristics of dengue fever in Guangzhou and provide a scientific basis for dengue fever prevention and control.Methods The data of dengue cases in Guangzhou,Guangdong Province reported between 2019 and 2023,were retrieved from the China Disease Prevention and Control Information System.Cross-sectional analysis was used to describe the temporal,spatial,and demographic distribution,and analyze the epidemiological characteristics.Results A total of 3518 cases of dengue fever were reported in Guangzhou from 2019 to 2023,including 3101 local cases(88.15%)and 417 imported cases(11.85%).The annual average incidence rate ranged from 0.09 to 17.59 per 100000 population.Imported dengue fever cases were reported in all months,with the peak reported from May to November(374 cases,89.69%).Local cases were first reported in May and the last in December,with the highest incidence from August to November(2960 cases,95.45%).The cases were reported in all 11 administrative districts;the top three were Baiyun District,Yuexiu District,and Liwan District.Male and female cases accounted for 53.52%and 46.48%,respectively;the age group mainly concentrated between 20-<60 years(2547 cases,72.40%).The top three occupations were business services(784 cases),housework and unemployment(738 cases),and retirees(596 cases).The average time from onset to diagnosis for local cases was 4.06 days,and 4.60 days for imported cases.The overseas imported cases mainly came from Southeast Asia 88.10%(311/353),with the most being imported from Cambodia.Cases imported from other provinces mainly came from Yunnan Province,and cases imported from other cities within the province mainly came from Foshan City.Conclusions In recent years,the incidence of dengue fever in Guangzhou has remained at a high level,with obvious imported and seasonal characteristics.Relevant departments should pay attention to key populations and take effective measures to reduce the density of mosquito vectors,and strictly prevent the sprea
