摘　　要：目的了解2016-2019年新疆流感样病例(influenza-like illness,ILI)的流行病学特征和病原学监测数据,为流感防控工作提供科学依据。方法通过中国流感监测信息系统收集2016-2019年新疆流感哨点医院报告的ILI、病原学监测数据和流感聚集性疫情报告资料,分析流行病学特征。结果2016年第14 w-2019年第13 w,新疆共报告门诊病例9820366例,其中流感样病例405394例,ILI%为4.1%;病例集中在15岁以下人群;检测样本38975份,检出流感病毒阳性6584份、阳性率16.9%,分离病毒株为新甲型H1N1型848株、H3型603株、BV型47株和BY型606株,聚集性疫情中病毒型别与当年流行的病毒型别一致。结论新疆流感疫情集中在每年的第40 w至次年第20 w,新甲型H1N1,B型和H3型交替流行;流感主要发生在冬春季,以学龄儿童为主;应加强学龄儿童的流感防控工作。Objective To understand the epidemiological characteristics and etiological data of influenza in Xinjiang from2016 to 2019,so as to provide scientific basis for the control and prevention of influenza.Methods Influenza-like cases(ILI),the etiological surveillance data and report information of clustering epidemic of influenza by sentinel surveillance hospitals in Xinjiang from 2016 to 2019 were collected from national information systems of influenza surveillance for analyzing epidemiological characteristics.Results From the 14 th week in 2016 to the 13 th week in 2019,there were 9820366 outpatients in Xinjiang,with 405394 cases of influenza-like cases(ILI),accounting for 4.1%(ILI%).The cases mainly concentrated in the age group less than 15 years.There were 38975 samples of throat swab of the ILI detected,with 6584 samples of the positive flu virus and positive rate of 16.9%,including 848 of H1 N1,603 of H3,47 of BV,and 606 of BY.The virus type in the clustering epidemic was the same as the prevalence type in the year.Conclusions The influenza epidemic in Xinjiang concentrates from the 40 th week of the year to the 20 th week of the next year,with A(H1 N1),B and H3 N2 sub-type of influenza alternately prevalent from 2016 to 2019.The prevalence is mainly in winter and spring,with the dominant cases in school-age children.It is necessary to strengthen the prevention and control of influenza in teenagers.
