摘要
目的分析江苏省白纹伊蚊密度和季节消长规律,为登革热和寨卡病毒病等伊蚊传播疾病的防控提供科学的预警信息。方法 2017年采用布雷图指数(BI)法监测伊蚊幼蚊密度,采用双层叠帐法监测伊蚊成蚊密度,利用描述性流行病学方法对江苏省登革热和寨卡病毒病疫情特征进行分析。不同生境BI通过两两独立样本t检验进行比较。结果 2017年江苏省共报告登革热病例24例,发病率为0.04/10万,寨卡病毒病病例2例,均为输入性病例。全省5-10月BI为1.73～4.89,8-9月BI较高,废品收购站和农村自然村BI明显高于居民区等。全省5-10月帐诱指数为0.64～6.27只/(顶·h),8-10月帐诱指数较高,旧轮胎堆放地、废品收购站、工地的帐诱指数明显高于公园、竹林和居民区。结论江苏省白纹伊蚊广泛分布,6-10月存在伊蚊传播疾病的输入和本地传播风险,应引起高度关注。
Objective To analyze the density and seasonal dynamics of Aedes albopictus in Jiangsu province and providescientific information for the prediction and control of diseases spread by the Aedes mosquitoes such as dengue fever andZika disease, etc. Methods Breteau index（BI） method was used to monitor the density of Aedes larvae, double layeredmosquito net method was used to monitor the density of adult Ae. albopictus, descriptive epidemiological approaches wereused to analyze the epidemiological data of dengue fever and Zika disease in Jiangsu province. t test of the two independentsamples was used to compare BI of different habitats. Results There were 24 cases of dengue fever in Jiangsu province in2017, with an incidence of 0.04/100 000, and two cases of Zika disease, all of which were imported cases. BI fluctuatedbetween 1.73-4.89 from May to October. BI was the highest in August and September. BI of material recycling station andrural village were obviously higher than the residential areas. The mosquito-net trap index fluctuated between 0.64-6.27/net·hour from May to October. The mosquito-net trap index from August to October was the highest. The mosquito-net trapindex of storage area of waste tires, recycling station and construction site were higher than parks/bamboo forests andresidential areas. Conclusion Aedes albopictus is widely distributed in Jiangsu province. The risk of imported and localoutbreak of the diseases spread by the Aedes mosquito should be highly concerned between June and October.
