广西柳州市常见蚊媒传染病流行风险评 估研究 吕榜军 陈蔚恩 梁忠福 俞泉宇 余钧池 柳州市疾病预防控制中心 摘要： 口的通过开展蚊媒传染病综合监测，并开展风险评估，为蚊媒传染病防控提供 依据。方法 蚊媒传染病分析采用描述性流行病学方法;成蚊密度监测采用诱蚊灯 法，白纹伊蚊专项监测采用诱蚊诱卵器法。利用聚合酶链式反应技术(PCR)检 测方法对收集到的蚊虫开展登革病毒、乙脑病原学检测;风险评估利用曾晓巩的 病媒生物风险评估体系并适当增加指标。结果柳州市2005-2016年共报告3种 蚊媒传染病计149例，年均发病率0. 35/10万，其屮乙型脑炎72例、疟疾74 例、登革热3例;2016年31月共捕获雌性蚊9 535只，以致倦库蚊为优势种群 占86. 49% (8247/9 535),其它依次为中华按蚊占6. 50% (620/9 535)、骚扰 阿蚊占4.16% (397/9 535)、白纹伊蚊占2.84% (271/9535);诱蚊诱卵器平均 指数达20. 45,公园平均指数最高25. 40,花鸟市场最低6. 26;共捕获到的8 247 只致倦库蚊用螺旋管分成成224份标本进行乙脑病毒核酸检测，结果显示有9 份为阳性，阳性率4. 02%;对捕获到的271只口纹伊蚊分装成14份进行登革热病 毒核酸检测，结果均为阴性。综合判断乙型脑炎、疟疾风险评价指数为低危险度 风险，登革热为中等危险度风险。结论开展蚊媒传染病风险评估是可行的;柳州 市登革热存在一定风险，需要加强蚊媒传染病监测和蚊媒孳生环境的综合治理。 关键词： 蚊媒传染病;流行特征;综合监测;风险评估; 作者简介：吕榜军(1977-)，男，副主任医师，主要研究方向:传染病预防与控 制，E-mail: lujun05@163. com 收稿日期：2017-05-18 基金：广西卫计委科技项目(Z2016016) Study on the integrated monitoring and risk assessment of main mosquito-borne diseases in Liuzhou City of Guangxi LV Bangjun CHEN Weien LIANG Zhongfu YU Quanyu YU Junchi Liuzhou City Center for Disease Control and Prevention; Abstract： Objective To provide evidence for prevention and control of mosquito-borne diseases by integrated monitoring and conducting risk assessment of mosquito-borne diseases. Met hods The data of mosquito-borne diseases were analyzed by the method of descriptive epidemiology; the lamp-trapping method was used for mosquito monitoring; and the mosq-ovi trap was used for Aedes albopictus moni toring; detection of Dengue virus and epidemic encephalitis B in mosquito by Poymerase Chain Rcaction; risk assessment was completed using the methld proposed by ZENG Xiaogong. Results A total of 149 cases of mosquito-borne diseases were reported accumulatively in Liuzhou during 2005-2016 with the annual average inci denee of 0. 35/100000, and there were 72 cases with epidemi c encephalitis B, 74 cases with malaria, 3 cases with dengue fever- From March to November 2016, 9 536 mosquitoes were captured. The predominant species is Culex pipien quinquefasciatus ( 86. 49%, 8 247/9
