摘　　要：采用描述流行病学的方法,分析了近5年北京市输入性伊蚊传播疾病病例的流行病学特征,以评估伊蚊传播疾病本地化风险。近5年来,北京市共输入伊蚊传播疾病病例107例,其中,寨卡病毒病病例3例,黄热病例5例、基孔肯雅热病例2例、裂谷热病例1例、登革热病例96例。寨卡病例均来自委内瑞拉,3例尿液核酸检测阳性,2例唾液核酸检测阳性、1例血标本阳性。5例黄热病病例均来自安哥拉,1例肾衰无尿,其余4例尿液核酸均阳性;1例血液标本阳性(1/5)、2例唾液标本阳性(2/4)。1例基孔肯雅热病例2017年来自孟加拉,另1例2019年来自缅甸,分别在入境检疫、入境后体检中发现。登革热病例96例,每月均有病例输入,夏秋季输入病例居多。北京市伊蚊传播疾病输入风险高且本地伊蚊构成比日益增加,存在本地续发感染风险,应加强检疫,提高接诊医生发现、报告意识和高危人群健康教育。The epidemiological characteristics of the imported Aedes mosquito-borne diseases in Beijing during 2016 to 2019 were described to determine the potential localization risk of the Aedes mosquito-borne diseases.In the past five years,a total of 107 cases of Aedes-borne diseases were imported,including 3 cases of Zika disease,5 cases of Yellow fever disease,2 cases of Chikungunya fever,one Rift fever case and 96 cases of Dengue fever.Among them,3 Zika cases from Venezuela were tested with positive nucleic acid in 3 urine samples,2 salvia samples and one blood sample.The 5 Yellow fever cases from Angola yielded positive nucleic acid in 4 urine sample(one case had no urine sample),2 saliva samples and one blood sample.Two Chikungunya fever cases,one from Bangladesh in 2017 and the other from Myanmar in 2019,were detected respectively in entry quarantine and post-entry physical examination.Only one Rift fever case from Angola were diagnosed by positive nucleic acid in blood and saliva samples.Dengue fever appeared to be predominant imported cases in Beijing,total 96 cases were reported annually peaked in summer and autumn seasons.With the increased proportion of Aedes mosquitoes in local Beijing,the recurrence risk of the Aedes borne diseases might be soaring.Quarantine should be strengthened to enhance the awareness of doctors visited to find and report timely and more health education to the public should also be carried out.
