| 摘 要： | 目的 了解辽宁省锦州市流行性感冒(流感)流行动态,为及时预警流感活动强度和流感的防治提供参考依据。 方法 收集锦州市2009-2011年流感样病例(ILI)监测数据和病原学检测数据,分析ILI占门诊就诊病例百分比(ILI%)、病毒分离率及流感病毒各亚型的变化规律。 结果 锦州市2009-2011年共报告ILI 26 483例,ILI%为2.86%;2009-2011年共采集3382份ILI咽拭子标本,其中阳性428份,平均病毒分离率为12.65%;其中甲型H1N1流感占阳性标本的42.52%。 结论 2011年各月份 ILI%均低于2010年,提示2011年流感病毒活动较2010年减弱;ILI%与病毒分离率之间正相关(rs=0.352,P=0.035), ILI%的变化能够较好地反映当地流感病毒的活动情况。

| Abstract: | Objective To understand the epidemiological characteristics of influenza in Jinzhou and provide scientific evidence for the early warning and control of influenza epidemic effectively.Methods The analysis was conducted on the surveillance and etiological detection data of influenza like illness(ILI),proportion of ILI cases in outpatient visits.Results A total of 26 483 ILI cases were reported in Jinzhou from 2009 to 2011.The ILI cases accounted for 2.86% of the total outpatient visits.Among the 3382 swabs detected during this period,428 were positive for influenza viruses(12.65%).Among the positive swabs,A(H1N1) pdm 09 viruses accounted for 42.52%.Conclusion The monthly ILI proportion in 2011 was lower than that in 2010,suggesting that the influenza activity was milder in 2011 than in 2010.The ILI proportion was positively correlated with the virus isolation rate(rs=0.352,P=0.035).ILI proportion can truly reflect the degree of local influenza activity. |
