目的分析2012-2013年内蒙古阿拉善盟地区流感病毒核酸检测结果,为防控工作提供科学依据。方法对国家级流感监测哨点医院(阿拉善盟中心医院)及三旗两区疾控中心送检的流感样病例(ILI)标本采用Real-Time RT-PCR方法进行流感病毒核酸检测。结果 2012-2013年内蒙古阿拉善盟地区共检测流感样病例(ILI)咽拭子407份,流感病毒核酸阳性63份,阳性率为15.48%。其中:季节性H3 25份,检出率为6.14%;甲型H1N1 24份,检出率为5.90%;B型流感14份,检出率为3.44%。结论 2012-2013年阿拉善盟地区主要流行季节性H3和甲型H1N1流感,伴有乙型流感散发。该地区流感流行呈冬春季高发的特点。流感的发病人群以0~19岁年龄段为主,是流感防控的重点人群。
Objective To analyze the detection results of influenza virus nucleic acid in Alxa League area in Inner Mongolia from 2012 to 2013, and provide a scientific basis for prevention and control. Methods Real-time RT-PCR was used to detect influenza virus nucleic acid in influenza-like illness cases (ILI) specimens from the National Influenza Surveillance Sentinel Hospital (Alxa League Central Hospital) and the Sanqikang CDC. Results A total of 407 throat swabs from influenza-like illness (ILI) were detected in the region of Alxa League in Inner Mongolia from 2012 to 2013. The positive rate of influenza virus nucleic acid was 63, with a positive rate of 15.48%. Of which: seasonal H325, the detection rate was 6.14%; 24 cases of type A H1N1, the detection rate was 5.90%; 14 influenza B, the detection rate was 3.44%. Conclusion The major epidemic seasonal H3 and H1N1 influenza in Alxa League region between 2012 and 2013, accompanied by influenza B (B-type) influenza. Influenza prevalence in the region was characterized by high incidence of winter and spring. The incidence of influenza in people aged 0 to 19 age-based, is the focus of influenza prevention and control of the crowd.
