【摘要】：目的分析2010-2014年石家庄市流感病毒监测资料,为流感,特别是甲型H1N1的防控提供科学依据。方法2010-2014年流感流行季,搜集石家庄市2家流感监测哨点医院流感样病例(Influenza-Like Illness,ILI)数据,采集部分ILI咽拭子标本,用Real Time RT-PCR方法进行病毒核酸检测。结果 2010-2014年流感流行季,2家哨点医院门(急)诊共报告ILI 338 846例,ILI就诊百分比为1.10%。采集ILI咽拭子标本1 926份,经流感病毒核酸检测阳性468份,阳性率24.30%,其中甲型H1N1、季节性H3N2、B型分别占50.00%、17.52%、32.48%,各监测年度ILI%高峰和检测阳性率高峰相一致。除2011-2012年度,其他均有甲型H1N1流感检出,其在2013-2014年流感流行季为优势流行株。2010-2011年与2012-2013年和2013-2014年相比,甲型H1N1流感阳性标本的年龄构成有差异(χ2=17.91,P0.01)。结论 2010-2014年流感流行季石家庄市流感活动较弱,甲型H1N1流感病毒流行常态化,与季节性H3N2和B型流感病毒成为主要流行型别。
[Abstract]:Objective to analyze the surveillance data of influenza virus in Shijiazhuang City from 2010 to 2014 so as to provide scientific basis for the prevention and control of influenza, especially H1N1. Methods Influenza case (Influenza-Like Illness,ILI) data were collected from two influenza surveillance sentinel hospitals in Shijiazhuang City from 2010 to 2014. Partial ILI throat swab samples were collected and virus nucleic acid was detected by Real Time RT-PCR method. Results during the influenza epidemic season from 2010 to 2014, two sentinel hospitals reported a total of 1. 10% of ILI 338846 cases of ILI. A total of 1 926 ILI throat swabs were collected and 468 were detected positive by influenza virus nucleic acid. The positive rate was 24.30. Among them, A H 1, seasonal H 3N 2 B accounted for 50 000 and 17. 522 2 + 32. 48, respectively. The peak of ILI% and the positive rate were the same in each monitoring year. Except for 2011-2012, all the other influenza A strains were detected. Compared with 2012-2013 and 2013-2014, the age composition of influenza A H1N1 positive samples was different (蠂 2, 17.91g / P0.01). Conclusion the influenza activity in Shijiazhuang from 2010 to 2014 is weak, and the influenza A H1N1 virus is common, and the seasonal H3N2 and B influenza viruses are the main epidemic types.
