摘　　要：目的分析2019年湖北省登革热疫情特征及媒介伊蚊监测数据,为制定有效的登革热防控措施提供依据。方法采用布雷图指数法和双层叠帐法监测媒介伊蚊幼蚊和成蚊密度,采用Excel 2016软件处理登革热病例和蚊媒监测数据并绘制图表。结果共报告登革热病例233例,其中本地感染病例30例;除神农架林区外,其余16个市(州)均有登革热病例报告;全年均有病例报告,病例高峰为6-11月,87.12%为输入性病例(203例),且81.36%的境外输入病例来自柬埔寨(144例);患者年龄主要集中在20~54岁(193/233,82.83%),职业以农民为主(73/233,31.33%),其次为家务及待业(41/233,17.60%),男女性别比例为3.02∶1,患者发病后平均就诊时间为6 d。白纹伊蚊密度高峰期在6-10月。结论2019年湖北省登革热疫情主要是由输入病例引起的本地暴发疫情,建议相关部门进一步做好媒介伊蚊和病例监测工作,为当地登革热防控措施选择提供科学依据。Objective To analyze the epidemiological characteristics of dengue fever and the surveillance data of Aedes vector in Hubei province,China,2019,and to provide a basis for formulating effective prevention and control strategies for dengue fever.Methods The Breteau index method and double-net method were used to monitor the density of Aedes larvae and adults.Excel 2016 software was used to process and tabulate the data of dengue cases and mosquito vector surveillance.Results A total of 233 dengue cases were reported,including 30 cases of indigenous infections.Apart from Shennongjia forest region,all the other 16 cities(prefectures)had reported cases.There were reported cases all year round,with a peak period in June to November.Among all the reported cases,87.12%(203 cases)were imported,and 81.36%(144 cases)of the imported cases were from Cambodia.The age of patients was mainly 20-54 years(193/233,82.83%);farmers were the dominant occupation(73/233,31.33%),followed by unemployed people(41/233,17.60%).The ratio of males to females was 3.02∶1.On average,they visited the hospital 6 days after onset.The peak density of Ae.albopictus occurred in June to October.Conclusion The dengue epidemic in Hubei province,2019 was a local outbreak caused by imported cases.It is suggested that relevant departments should strengthen surveillance of the Aedes vector and dengue cases,so as to provide a scientific basis for the selection of local dengue prevention and control measures.
