摘　　要：目的 通过对2006-2013年马鞍山市流感监测结果进行分析,探索流感流行规律,为制定流感防治措施提供依据。方法 对马鞍山市2006-2013年流感监测年度的流感样病例（influenza-like illness,ILI）监测资料、病原学监测资料进行分析。结果 2006-2013年马鞍山市流感监测哨点医院的平均ILI就诊百分比（ILI%）为6.72%,流感发病呈现冬春季及夏季两个峰,病例以15岁以下的少年儿童为主。2006~2009年7月,病毒分离平均阳性率为8.13%,毒株类型以季A（H1N1）和B型交替出现为主;2009年8月~2013年,核酸检测平均阳性率为18.40%,以新甲（H1N1）、季A（H3N2）和B型交替出现为主。结论 2006-2013年马鞍山市流感活动相对稳定,但流感监测工作仍然不能放松,需加强对B型流感的监测与防控。Objective To explore the epidemiological pattern of influenza by analyzing influenza surveillance data in Maanshan city between 2006 and 2013, and to provide evidence for the government decision. Methods Surveillance data of influenza-like illness （ILl） （ including clinical data and virological surveillance data） in Maanshan from 2006 to 2013 were analyzed. Results ILl cases accounted for 6.72% of the total cases in sentinel hospitals in Maanshan. A 2- peaked epidemiological pattern （ in winter-spring and summer） was found influenza-like illness in outpatients, Most of the ILI cases had the ages less than 15 years. The average positive rate of the influenza virus isolated from patients was 8.13% , and the types of strains were type A （ H1N1 ） and type B which appeared alternately before July 2009. The average positive rate of the virus nucleic acid was 18.40% after August 2009, and the types of strains were type new A （ H1N1 ）, type A （H3N2） , and type B that appeared alternately. Conclusions Prevalence of influenza in Maanshan remained stable be- tween 2006 and 2013. However, influenza surveillance should still be performed carefully. Surveillance and prevention of type B influenza should be strengthened.
