摘　　要：目的了解云南省新平县流行性乙型脑炎流行状况及其特征,为云南省乙脑的防治提供科学依据。方法在观察点采集蚊虫进行乙脑病毒分离和鉴定,对观察点正常人群采用酶联免疫吸附试验（ELISA）检测乙型脑炎Ig G抗体。结果共采集到蚊虫5属21种6 628只,其中三带喙库蚊属于当地优势蚊种,占蚊虫捕获总数的71.59%;共分离到2株乙脑病毒;正常人血清乙脑病毒抗体阳性率为74.67%,其中〉16岁年龄组的阳性率最高,达到了95%,0～5岁年龄组与其他组人群乙脑病毒抗体水平差异有统计学意义。结论三带喙库蚊和中华按蚊均为携带和传播乙型脑炎病毒的媒介,当地健康人群中存在较高的乙型脑炎病毒隐性感染现象。Objective To explore the presence of Japanese encephalitis in Xinping county,and to provide scientific basis for prevention and control of JE in Yunnan Province. Methods Mosquitoes were captured in the field sites and the virus was isolated and identified,normal population encephalitis antibody Ig G was texted by enzyme-linked immunosorbent assay（ ELISA）. Results Collected mosquitoes in total of 6628 belong to 5categories 21 types,among which the Culex tritaeniorhynchus belonged to local main predominant mosquito species,accounted for 71. 59% of total mosquitoes collected. Total of 2 JEV strains were identified. In the normal serum,Japanese encephalitis virus antibody-positive rate was 74. 7%,of those the adult 〉16 years old was the highest（ about 95%）. There was significant difference between 0-5 age group and other groups infected JEV. Conclusions Culex tritaeniorhynchus and anopheles sinensis are both vectors to carry and spread JEV,the inapparent infection of epidemic Japanese encephalitis virus was high in the local normal residents.
