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 epidemiological types and epidemiological characteristics of influenza surveillance in Wenzhou City from 2009 to 2014, and provide basis for the prevention and control of influenza. Methods The real-time fluorescence quantitative PCR was used to detect the nucleic acid of nasopharyngeal swab specimens from influenza-like cases (ILI) collected from sentinel hospitals. The results were statistically analyzed. Results Sentinel Hospitals monitored a total of 7,885,356 outpatient and emergency department cases in 2009-2014, of which ILI 291 151 cases (3.69%). In the 6 years, a total of 4 726 samples were tested positive for 684 samples, the positive rate was 14.47%. Among the detected influenza types, type B was the most, followed by novel H1N1. Among 5 age groups, the positive rate of 6 to 15 years Highest (27.10%). Conclusion The prevalence of influenza virus in the city in winter and spring is high with small peak in summer. The prevalence of influenza is mainly in the epidemic of type B, new type H1N1 and type H3 subtypes. Influenza surveillance and prevention and control have achieved some results. Need to strengthen the pre-school children and primary and secondary prevention and control of influenza.
