【摘要】：目的对2006-2012年湖北省流感监测结果进行分析,为湖北省的流感防控工作提供科学依据。方法通过流行病学调查及病原学监测,对湖北省近年的流感流行状况进行分析。结果 2006-2012年,湖北省共报告297起流感样病例暴发疫情,流感样病例(influenza-like illness,ILI)比例平均为4.63%;0~5岁年龄组人群在ILI中所占比重最大,为50.71%;随着年龄的增长,ILI比例逐渐递减,60以上年龄组人群所占比重最低,仅为2.24%。各年龄组流感样病例比例随时间呈现季节性差异,疫情报告的时间分布主要为每年春节前后及开学季。毒株型别分布呈现交替流行态势,且除2011年外,其余年度均呈现冬春季及夏季两个流行高峰。结论湖北省流感流行峰及优势毒株呈现季节性及交替分布态势,长期稳定的病例及病原学监测可以为流感疫情的预警、疫苗株的选择提供良好的实验室依据。
[Abstract]:Objective to analyze the results of influenza surveillance in Hubei Province from 2006 to 2012, and to provide scientific basis for the prevention and control of influenza in Hubei Province. Methods the epidemic status of influenza in Hubei Province in recent years was analyzed by epidemiological investigation and etiological surveillance. Results from 2006 to 2012, a total of 297 influenza-like cases were reported in Hubei Province, and the proportion of influenza like cases (influenza-like illness,ILI) was the largest in ILI in the age group of 5 years old. With the increase of age, the proportion of ILI in the group above 60 was the lowest (2.24%). The proportion of influenza-like cases in different age groups showed seasonal differences with time. The time distribution of epidemic reports was mainly before and after Spring Festival and the beginning of each year. The distribution of virulent strains showed an alternate epidemic trend, and the other year showed two peaks in winter, spring and summer except in 2011. Conclusion the epidemic peak and dominant strains of influenza in Hubei Province show seasonal and alternating distribution trend. Long-term and stable surveillance of cases and etiology can provide a good laboratory basis for the early warning of influenza epidemic situation and the selection of vaccine strains.
