摘　　要：目的了解安岳县流感流行状况,为制定流感防制策略提供依据。方法通过国家疾病监测信息报告管理系统、突发公共卫生事件报告管理信息系统和流感/人禽流感专报系统收集流感及流感样病例(ILI)监测资料,对流行病学、病原学以及流感暴发疫情监测结果进行分析。用MDCK细胞分离病毒,用血凝抑制试验鉴定毒株。结果安岳县2005-2011年哨点医院报告的周平均ILI就诊百分比(ILI%)为0.62%,最低为2011年第11周(0.05%),最高为2009年第37周(8.59%),2009年因受甲型H1N1流感大流行影响出现明显就诊高峰,同年报告流感发病率为9.82/10万。共报告流感暴发疫情7起,主要在9月,以农村中小学为主。在491份ILI标本中共分离到流感毒株59株,分离率12.02%。结论 2005-2011年安岳县报告的ILI较为平稳,农村中小学是流感暴发疫情的高发场所。需要加强流感监测、人群抗体水平及流感病毒抗原变异研究,同时加强农村中小学暴发疫情监测。Objective To provide scientific basis for the prevention of influenza by understandiing the epidemiological characteristics of influenza in Anyue county.Methods Collected the data of influenza-like illness(ILI) and influenza cases through the national diseases reporting information,emergency public reporting and influenza surveillance information system,with the results of epidemiology,etiology and outbreaks of influenza analyzed.The MDCK cell were used for separation of virus,and the isolated strain was typed and serum antibody measured through hemagglutination inhibition(HI) test.Results.In Anyue county from 2005 to 2011,the weekly average visiting rate of ILI was 0.62%,which was lowest in the 11th week of 2011 and highest in the 37th week of 2009.Because of the H1N1 influenza A pandemic in 2009,there was an obvious visiting peak in 2009,and the reported influenza incidence rate was 9.82/105.Seven outbreaks of influenza were reported,,mainly in September,and almost happened in rural elementary and middle schools.There were 59 strains of virus isolated from 491 specimens,with the isolation rate of 12.02%.Conclusion The reported ILI in Anyue county from 2005 to 2011 is steady,rural primary and middle school is the high risk place of outbreak.Influenza monitoring,study on population antibody levels and virus antigen variation should be strengthened,with the outbreak surveillance of countryside elementary and middle schools enhanced.meanwhile.
