【摘要】：目的比较广州市2014-2016年流感监测数据,分析其流感流行特征,为流感防控政策的制定提供依据。方法采用多重实时荧光PCR(Real-time PCR)对标本进行流感病毒核酸检测,用Excel 2010建立数据库与绘图分析,用SPSS16.0软件作统计分析。结果 2014-2016年共采集标本10 743份,流感病毒核酸阳性率为12.1%。2014与2015年呈双峰流行,流行时间在春夏季,2014年为新甲型H1N1型和H3型流感流行,2015年为B型和H3型流感流行,2016年呈单峰流行,流行时间为夏季,为新甲型H1N1型流感流行。不同年龄组的流感病毒核酸阳性率以及各型别的流感病毒核酸阳性率的差异有统计学意义,不同性别的流感病毒核酸阳性率以及各型别的流感病毒核酸阳性率的差异均无统计学意义。结论广州市流感高峰期出现在春夏季,1年有1次或2次流行高峰,呈不同流感型别交替流行。流感病毒的感染情况有年龄差异而无性别差异。每年10-12月是最佳的疫苗接种时间,婴幼儿和老年人为疫苗接种的重点对象,加强中小学生疫苗接种工作,有利于流感的防控。
[Abstract]:Objective to compare the influenza surveillance data from 2014 to 2016 in Guangzhou and analyze the epidemic characteristics of influenza in order to provide evidence for the formulation of influenza prevention and control policy. Methods the influenza virus nucleic acid was detected by multiplex real-time fluorescence PCR (Real-time PCR). The database was established by Excel 2010, and the statistical analysis was made by SPSS16.0 software. Results A total of 10 743 specimens were collected from 2014-2016. The positive rate of influenza virus nucleic acid was 12.1. the influenza virus nucleic acid positive rate was 12.1. the epidemic time was in spring and summer, the new influenza A / H1N1 and H3 were prevalent in 2014, the influenza B and H3 were epidemic in 2015, and in 2016, there was a single peak epidemic. The epidemic time is summer, is the new type A H1N1 influenza epidemic. The positive rate of influenza virus nucleic acid and the positive rate of influenza virus nucleic acid in different age groups were significantly different. There was no significant difference in the nucleic acid positive rate of influenza virus and the nucleic acid positive rate between different types of influenza virus. Conclusion the peak period of influenza in Guangzhou is in spring and summer, and there are one or two epidemic peaks in a year. The infection of influenza virus varies in age but not in sex. October to December each year is the best vaccination time, infants and the elderly as the focus of vaccination, strengthen the primary and secondary school students vaccination work, is conducive to the prevention and control of influenza.
