摘要
目的对2009年-2014年温州市流感监测结果的病原学型别及流行病学特征进行分析,为流感的防控提供依据。方法采用实时荧光定量PCR对流感监测哨点医院采集的流感样病例（ILI）鼻咽拭子标本进行核酸检测,并对结果进行统计和分析。结果 2009年-2014年哨点医院共监测门急诊病例7 885 356例,其中ILI 291 151例,占3.69%。6年共检测样本4 726份,阳性684份,阳性率为14.47%,检出的流感型别中以乙型最多,新型H1N1次之;5个年龄组中,6岁-15岁组阳性率最高（27.10%）。结论本市6年流感病毒流行以冬季、春季高发,夏季伴有小高峰,主要以乙型、新型H1N1型、H3型3个亚型交替流行为主;流感监测和预防控制取得一定成果;重点需加强学龄前儿童和中小学生的流感防治工作。
Objective To analyze the etiological types and epidemiological characteristics of influenza surveillance results in Wenzhou from 2009 to 2014,so as to provide the scientific basis for the control and prevention of influenza. Methods Throat swab specimens of influenza like illness（ ILI） were collected from national influenza surveillance sentinel hospitals for nucleic acid detection by real- time PCR,and the results were conducted for statistical analysis. Results A total of 7 885 356 cases from outpatients were monitored,among whom,291 151 patients were influenza- like illness,accounting for 3. 69%. Among six years,4 726 ILL nucleic acid specimens were detected,and 684 samples were positive,with the detection rate of 14. 47%.Influenza type B was the most,followed by the new H1N1. In the 5 age groups,the positive rate of 6- 15 years old group was the highest（ 27. 10%）. Conclusion The epidemic peaks of influenza were winter and spring,with a small peak in summer during the 6 years,and the dominant strains alternated among influenza type B,H1N1 and H3. Influenza surveillance,prevention and control have made a certain achievement; while,the prevention and control of influenza should be strengthened in preschool children and the primary and middle school students.
