[目的]了解济南市流行性感冒(流感)流行动态及病毒变化情况,为进一步做好流感预防控制工作提供科学依据。[方法]对2008～2009年度济南市流感监测资料进行分析。[结果]2008年10月至2009年3月,2所监测哨点医院合计报告内科、儿内科门诊急诊病例100706例,其中流感样病例1920例,占1.91%。检测咽拭子标本388份,分离到流感病毒61株,分离率为15.72%。61株流感病毒中,季节性流感H1N1亚型占72.31%,季节性流感H3N2亚型占9.84%,B(Victoria)亚型占13.11%,B(Yamagata)亚型占1.64%,未定型占3.28%。[结论]2008～2009年度流感流行季节流感优势毒株为季节性A/H1N1亚型,并逐渐过渡为A/H3N2亚型与B型。
[Objective] To understand the epidemiological and epidemic situation of influenza in Jinan City and to provide a scientific basis for further prevention and control of influenza. [Methods] Influenza surveillance data in Jinan City from 2008 to 2009 were analyzed. [Results] From October 2008 to March 2009, the two monitored sentinel hospitals reported a total of 100,706 outpatient emergency cases of internal medicine and pediatrics, of which 1920 were influenza-like cases, accounting for 1.91%. 388 samples of throat swabs were detected, and 61 strains of influenza viruses were isolated with the isolation rate of 15.72%. Among the 61 strains of influenza virus, seasonal influenza H1N1 subtype accounted for 72.31%, seasonal influenza H3N2 subtype accounted for 9.84%, B (Victoria) subtype accounted for 13.11%, B (Yamagata) subtype accounted for 1.64%, unspecified accounted for 3.28 %. [Conclusion] The predominant seasonal flu strains of influenza in 2008-2009 were seasonal A / H1N1 subtype and gradually transformed into A / H3N2 subtype and B type.
