摘要
目的分析2006~2007年北京市流感流行特征,为控制流感提供科学依据。方法收集北京市流感样病例监测资料、病原学资料和集中发热疫情资料进行分析。结果2006~2007年北京市流感活动平稳,流行高峰集中在2007年元旦前后,流行优势毒株为H3N2亚型,进入12月以后H1N1和B型流感病毒活动强度有所增加。集中发热疫情主要集中在中小学校(90%),疫情高发时间和病原学检测结果均与监测情况一致。结论采用同一标准开展流感样病例监测和病原学监测工作,对于掌握该市流感流行规律有着重要意义。
Objective This study aims to analyze data of influenza surveillance in Beijing during 2006 to 2007 for scientific evidence of its effective control. Methods Surveillance data of influenza-like illness (ILI) cases, viral isolation and clustering of fever cases were analyzed. Results Occurrence of influenza was at a stable status in Beijing during 2006 to 2007, with a peak around the new year's day of 2007 and a dominant influenza virus strain of A(H3N2). Activity intensity of influenza A( H1 N1 ) and influenza B viruses increased since December 2006. About 90 percent of clustering of fever cases occurred in primary and secondary schools, and results of laboratory examinations coincided with surveillance data during period of high incidence. Conclusion Surveillance of ILI and isolation of influenza virus with the same criteria play a significant role for understanding rule of influenza epidemic.
