摘要 目的了解2010~2011年绵阳市流感流行状况,为制定预防控制策略提供依据。方法收集绵阳市2010~2011年流感样病例(ILI)监测资料、流感病毒病原学监测结果以及暴发疫情信息进行分析。结果 2010年共上报ILI 12 100例,ILI就诊比(ILI%)为2.72%。2011年报告ILI 8 364例,ILI%为1.83%,较2010年减少32.47%。两个年度中,ILI就诊比例的时间分布均呈"双峰"型增高。病例以0岁~最多,占46.24%。发热门诊的ILI%最高,为88.56%。共采集788份ILI病例标本,核酸检测阳性标本共34份,阳性率为4.31%,包括甲型H1N1流感病毒5份(0.63%),A型未分型流感病毒8份(1.02%),季节性H3型流感病毒1份(0.13%),B型流感病毒20份(2.54%)。两年中未发生流感暴发疫情。结论 2010~2011年绵阳市流感发病相对稳定,未发生较大规模的暴发流行。哨点医院ILI报告质量有待提高,流感监测网络实验室应积极准备开展流感病毒分离工作,加强对各型流感病毒的监测,以预防、控制流感的流行。 Objective To investigate the epidemical status of influenza in Mianyang during 2010-2011, so as to provide evidence for formulating prevention and control strategies. Methods Surveillance data, ILI etiological results, outbreak and epidemic situation of the influenza-like illnesses (ILI) in Mianyang during 2010-2011 were collected for analysis. Results There were 12 100 ILI cases reported in 2010, accounted for 2.72% of the total outpatients. While 8 364 ILI cases accounted for 1.83% of the total outpatients were reported in 2011, reduced by 32.47% compared with 2010. The temporal distribution of doctor-visiting ratio in those two years was in an increased bimodal pattern. Most cases were children aged 0-5 years, accounted for 46.24%. Most ILI cases were treated in the department of fever, accounted for 88.56%. A total of 788 ILI specimens were collected for the detection of Real time RT-PCR, of which 34 specimens showed positive strains (4.31%) including 5 influenza A/H1N1 (0.63%), 8 influenza A (1.02%), 1 seasonal influenza A/H3 (0.13%) and 20 influenza B (2.54%). No outbreak and epidemic situation in Mianyang during 2010-2011. Condusion The inluenza activity is relatively stable without large-scale outbreak in Mianyang during 2010-2011. The reporting quality of surveillance hospitals should be improved and the lab of flu surveillance network should actively prepare to do the isolation and identification of influenza virus. It is necessary to enhance flu surveillance so as to prevent and control influenza prevalence.
