摘要: 目的 分析2019年我国23个项目省(自治区、直辖市)媒介伊蚊监测数据,为登革热为代表的媒介伊蚊传播疾病防控提供依据。方法 收集我国上述各监测地区媒介伊蚊监测点的媒介伊蚊幼蚊及成蚊监测数据,利用SPSS 18.0软件进行统计分析,对登革热进行初步的风险评估。结果 2019年我国平均布雷图指数(BI)为3.56,平均诱蚊诱卵指数(MOI)为4.89。浙江、海南、福建省监测期内重点月份平均BI > 10,云南省监测期内重点月份部分监测点BI > 5。广东省和广西壮族自治区(广西)监测期内重点月份MOI > 5。江西、安徽、重庆、湖南、河南、四川和湖北省(自治区)监测期内绝大多数月份BI > 5,湖南省6-8月、贵州省7-9月MOI > 5,达到登革热传播风险。河北省监测期内BI > 10,陕西省7-8月、山东省8-9月BI > 5。广西、福建和江苏省(自治区)监测期内大部分月份,湖北省6-7月,陕西和四川省9月成蚊密度(帐诱指数)超过2只/(顶·h)。结论 2019年我国绝大多数项目省(自治区、直辖市)媒介伊蚊密度超过登革热传播或暴发阈值,登革热本地传播及暴发风险高。建议各地持续加强媒介伊蚊监测和风险评估,促进我国媒介伊蚊可持续精准控制,预防控制媒介伊蚊传播疾病的暴发流行。

Abstract: Objective To analyze the Aedes surveillance data of 23 project provinces (autonomous regions and municipalities directly under the central government) in China, 2019, and to provide scientific evidence for the prevention and control of Aedes-borne diseases such as dengue. Methods The surveillance data of larval and adult Aedes mosquitoes from the surveillance sites of the 23 regions were analyzed using SPSS 18.0 software for a preliminary assessment of the risk of dengue transmission. Results In China, 2019, the mean Breteau index (BI) of Aedes mosquitoes was 3.56, and the mean mosquito ovitrap index (MOI) was 4.89. During the key months of the surveillance periods, the mean BI exceeded 10 in Zhejiang, Hainan, and Fujian provinces, and exceeded 5 in some surveillance points of Yunnan province. MOI was over 5 in Guangdong province and Guangxi Zhuang autonomous region during the key months of the surveillance periods. In Jiangxi, Anhui, Hunan, Henan, Sichuan, and Hubei provinces and Chongqing municipality, BI exceeded 5 in most months of the surveillance periods; MOI exceeded 5 in Hunan province from June to August and in Guizhou province from July to September, reaching the spreading risk of dengue. During the surveillance periods, BI exceeded 10 in Hebei province, and exceeded 5 in Shaanxi province from July to August and in Shandong province from August to September. The density of adult mosquitoes (net trap index) was more than 2 mosquitoes/net·hour in Fujian and Jiangsu provinces and Guangxi autonomous region during most months of the surveillance periods, in Hubei province from June to July, and in Shaanxi and Sichuan provinces during September. Conclusion In 2019, the densities of Aedes mosquitoes in most project provinces (autonomous regions and municipalities directly under the central government) of China exceed the transmission or outbreak threshold of dengue, indicating a high risk of local transmission and outbreak of dengue. Aedes surveillance and risk assessment should be strengthened continuously to ensure sustainable and precise control of Aedes mosquitoes and Aedes-borne diseases.
