中文摘要:
      目的:分析探讨2009~2012 年武威市流行性感冒(简称流感)的流行特征,为流感的防控提供科学依据。方法:收集2009 年6 月~2012 年12 月武威市流感样病例及病原学监测资料,分析流感样病例就诊比(ILI%)的变化规律、流感样病例的年龄分布和流 感病毒各亚型的变化。结果:2009~2012 年,武威市的ILI%分别是1.94%、1.55%、1.12%、1.15%,ILI%高峰分别出现在6 月(2009 年)、7 月(2010 年)和10 月~次年3 月(2011 年和2012 年)。ILI年龄构成显示病例以15 岁以下人群为主。2009~2012 年,ILI样 本病原学检测阳性率为19.00%;2009 年,甲型H1N1 为优势毒株,构成比是76.64%,2010 年为季节性H3(60.00%)、B 型(29.23%) 混合流行;2011 年主要是甲型H1N1(26.47%)、季节性H3(29.41%)、A 未分型(29.41%);2012 年为季节性H3(31.78%)、B 型 (53.49%)混合流行。结论:2009 年甲型H1N1 流感大流行之后,武威市流感的活动较为平稳,流行优势毒株不断发生变化。
英文摘要:
      Objective:To describe and analyze the influenza characteristics in Wuwei city from 2009 to 2012, and to provide a scientific basis for influenza control.Methods:Influenza-like cases data and influenza virus surveillance data of Wuwei City from June 2009 to December 2012 were collected to analyze the regularity trend of ILI%(influenza-like illness consultation ratio), the distribution of the ILI ages and the activity discipline of each influenza virus type.Results:The ILI%of 2009-2012 in Wuwei City were 1.94%, 1.55%, 1.12%and 1.15% respectively and the ILI%peak times were June (2009), July (2010) and October to the following March (2011 and 2012) respectively. The ages of ILI were mainly under 15 years. 2009-2012, the pathogen detection positive rate of ILI samples was 19.00%; 2009, A (H1N1) was the dominant strain, the constituent ratio was 76.64%; 2010, it was mixed epidemic in seasonal H3 (60.00%) and B-type (29.23%); 2011, the epidemic strain were mainlyA (H1N1)(26.47%), seasonal H3 (29.41%) and A unclassified (29.41%); 2012, it was mixed epidemic in seasonal H3 (31.78%) and B-type (53.49 %).Conclusion:After the influenza A(H1N1) 2009 pandemic, the epidemic of influenza was relatively stable in Wuwei and the epidemic strain was constantly changing.
