[目的]了解流感病毒的活动规律,为控制流感的发生和流行提供科学依据。[方法]对2009年6月至2010年6月(2009~2010年度)惠州市流感监测资料进行分析。[结果]惠州市监测哨点医院2009~2010年度合计报告流感样病例22 143例,占就诊病人总数(269 972例)的8.20%。检测985例流感样病例咽拭子标本,流感病毒核酸阳性369例,阳性率为37.46%。阳性者中,甲型H1N1阳性的占46.07%,季节性H3N2型阳性的占30.89%,季节性H1N1型阳性的占3.79%,乙型阳性的占11.65%。本年度报告流感暴发疫情4起,合计发病52例,其中3起是甲型H1N1流感。[结论]2009~2010年度流感处于相对平稳状态,甲型H1N1流感病毒是优势毒株,但也存在季节性流感病毒。
[Objective] To understand the activity of influenza virus and provide a scientific basis for controlling the occurrence and prevalence of influenza. [Methods] Influenza surveillance data of Huizhou from June 2009 to June 2010 (2009 ~ 2010) were analyzed.

Throat swab specimens were detected in 985 cases of flu-like illness. The influenza virus nucleic acid positive 369 cases, the positive rate was 37.46%. Among the positives, 46.07% were positive for type A H1N1, 30.89% for seasonal H3N2 type positive, 3.79% for seasonal H1N1 type positive and 11.65% for type B positive. This year’s report of influenza outbreaks 4, a total of 52 cases of onset, of which 3 are Influenza A H1N1 influenza.
