摘　　要：目的分析2017—2022年眉山市报告的登革热病例的流行病学特征及蚊媒监测情况,为登革热疫情防控提供参考。方法采用WPS 2022及SPSS 21.0软件对2017—2022年眉山市报告的登革热病例资料及蚊媒监测数据汇总整理及统计分析,以P<0.05为差异有统计学意义。结果2017—2022年眉山市报告的19例登革热病例均为柬埔寨输入;发病时间集中在7至8月;发病群体多为外出务工的中青年农民工;发病到就诊时间间隔为0~17 d,中位数为7.5 d;农村居民就诊及时性较差(Z=-3.67,P<0.001)。蚊媒监测结果显示,布雷图指数及帐诱指数在2019年最高,高峰期在6至8月。结论眉山市登革热病例为东南亚疫区输入,蚊媒监测结果与疫情发展趋势相吻合。病例分布和就诊及时性均提示农民及农村地区登革热防控薄弱,应加强防控工作,避免因输入病例引起本地疫情传播。Objective To analyze the epidemiological characteristics and mosquito vector surveillance of dengue fever cases reported in Meishan City from 2017 to 2022,and to provide reference for the prevention and control of dengue fever.Methods WPS 2022 and SPSS 21.0 software were used to collect and analyze the data of dengue fever case and mosquito vector surveillance reported in Meishan City from 2017 to 2022.The difference P<0.05 was considered statistically significant.Results The 19 dengue cases reported in Meishan City from 2017 to 2022 were all imported from Cambodia.The onset time was concentrated in July to August.Most of the patients were young and middle-aged migrant workers who went out for work.The time interval from onset to treatment was 0 to 17 days,with a median of 7.5 days.The timeliness of medical treatment in rural residents was poor(Z=-3.67,P<0.001).The results of mosquito surveillance showed that Breteau index and trap index were the highest in 2019,and the peak period was from June to August.Conclusions The dengue fever cases in Meishan City were imported from the epidemic area of Southeast Asia,and the results of mosquito-borne surveillance were consistent with the development trend of the epidemic.The distribution of cases and the timeliness of medical treatment suggest that the prevention and control of dengue fever in farmers and rural areas is weak,and the prevention and control efforts should be strengthened to avoid the transmission of local epidemics caused by imported cases.
