【摘要】 目的了解北京首都国际机场周边蚊媒分布情况,为在2015年达到北京全市消除疟疾目标提供科学依据。方法蚊虫监测方法采用国家标准GB/23797-2009中的诱蚊灯捕获法。采用描述性研究的方法对首都机场周边蚊媒监测数据进行流行病学分析,通过SPSS 16.0软件作统计学处理。结果机场周边蚊密度指数为11.13只/灯.h,淡色库蚊为优势蚊种,占87.95%;监测点中以温榆河水蚊密度指数最高,为29.59只/灯.h;从时间分布上看,主要集中在8、9月份,占捕蚊总数的82.0%;蚊密度与气温有相关性(Pearson相关系数为0.606,P=0.004);多因素分析发现月份和地点是影响蚊密度的主要因素,但二者之间没有表现出交互作用。结论首都机场周边发生输入性疟疾病例而导致本地传播的风险很小。更多还原

【Abstract】 Objective To understand the distribution and density of mosquito vectors around the Capital International Airport in Beijing,and to provide scientific evidence for reaching the goal of eradicating malaria in Beijing in 2015.Methods According to GB/23797-2009,light-traps were used to capture mosquito.Epidemiological analysis was carried out on data of mosquito monitoring around the Capital International Airport and SPSS 16.0 software was applied for statistical analysis.Results The mosquito density was 11.13 per light per hour.Culex pipiens pallens was found to be dominant(87.95%).Mosquito density in Wenyu river was the highest of 29.59 per light per hour.The highest density appeared in August and September which accounted for 82% of total.Mosquito density was closly related to temperature(related coefficient was 0.606,P=0.004).Multivariate analysis revealed that season and region were major factors which influenced the mosquito density,but these two factors had no interaction.Conclusions The risk of transmitting malaria by mosquito vectors around capital international airport in Beijing was low.更多还原
