摘要
目的了解广元市流感流行特征与流感病毒亚型分布情况,分析其流行趋势,为流感防控提供科学依据。方法 收集2009-2010年度广元市各哨点医院流感样病例(Influenza-Like Illness)监测资料、病原学监测结果及暴发疫情信息,用统计学方法对监测结果进行分析。结果2009—2010年度全市哨点医院共报告流感样病例(ILI)8 702例,流感样病例就诊百分比(ILI%)平均为2.95%(8 702/295 490)。采集流感样病例标本327份,病原学检测阳性率为59.02%,其中新甲型H1N1占70.98%,其次季节性流感甲型H3亚型占15.54%。本年度发生流感样病例聚集性暴发疫情15起,多发生在中小学校和监管场所等处。结论新型甲型H1N1是2009-2010年度广元市流感流行的优势型别,暴发疫情多发生人群聚集的环境。
Objective To learn about the epidemic pattern of influenza and subtype distribution of influenza virus in Guangyuan and provide scientific evidence for influenza prevention and control.Methods The data of influenza-like illness（ILI） and etiological surveillance results and the information of outbreak during 2009-2010 in Guangyuan were collected and analyzed by using descriptive method.Results A total of 8702 ILI cases were reported by sentinel hospitals from May 2009 to April 2010,the average proportion of ILI cases in outpatients was 2.95%.Totally 327 samples were taken from ILI cases and the positive rate of etiological detection was 59.02%.During 2009-2010,2009 pandemic influenza A（H1N1） virus was predominant,accounting for 70.98%,followed by seasonal influenza A（H3） virus（15.54%）.A total of 15 outbreaks were reported during this period,most occurred in primary/middle schools and correctional facilities.Conclusion 2009 pandemic influenza A（H1N1） was the predominant subtype in Guangyuan during 2009-2010 and the epidemic peak was in September 2009.
