目的分析岱山县2008—2012年登革热相关蚊媒监测结果,为登革热流行风险的预测、预警和制定防治对策提供依据。方法采用描述性流行病学分析方法,对岱山县2008—2012年各监测点媒介监测资料进行统计分析。结果岱山县伊蚊主要为海滨伊蚊;白纹伊蚊成蚊密度在0~1.20只/人工小时之间,海滨伊蚊成蚊密度在0.00~15.60只/人工小时;2008—2012年每年6—10月监测伊蚊布雷图指数(BI),其中在大多数月份(22/25)均超过5年的安全水平,最高BI达41,房屋指数(HI)在4~33之间,容器指数(CI)在2.45~22.53之间,阳性容器以永久性容器为主,阳性率为10.06%。结论岱山县2008—2012年大部分月份伊蚊幼虫BI、HI、CI偏高,但结合成蚊监测结果表明,这一现象是由海滨伊蚊造成的,对输入性登革热传播风险不大。
Objective To analyze the surveillance results of Dengue related mosquito vectors from 2008 to 2012 in Daishan County, and to provide the basis for the prediction, early warning and prevention and treatment of dengue fever epidemic risks. Methods Descriptive epidemiological analysis was used to analyze the data of media monitoring at various monitoring sites in Daishan County from 2008 to 2012. Results Aedes albopictus in Daishan County was mainly Aedes albopictus; the Aedes albopictus density was between 0 and 1.20 per artificial hour; the Aedes albopictus density ranged from 0.00 to 15.60 / artificial hour; - The mosquito Brett Index (BI) was monitored in October, with safety levels exceeding 5 years for most months (22/25), with a maximum BI of 41 and a housing index (HI) of between 4 and 33, with a container index (CI) ranged from 2.45 to 22.53. The positive vessels were mainly permanent vessels with a positive rate of 10.06%. Conclusion The BI, HI and CI of Aedes larvae were high in most months of 2008-2012 in Daishan County. However, the results of mosquito monitoring showed that this phenomenon was caused by Ae. Albopictus and had little risk of transmission of imported dengue fever.
