【摘要】：目的分析2013-2016年度淄博市流感的流行特征。方法从中国流感监测信息系统收集2013-2016年度淄博市流感样病例监测资料、病原学监测资料及暴发疫情资料进行分析。结果淄博市2013-2016年度共报告流感样病例(ILI)21 182例,流感样病例百分比(ILI%)为2.44%。3个年度ILI%分别为2.30%、2.38%、2.64%。合计检测ILI标本4 459份,其中流感病毒阳性510份,阳性率为11.44%。ILI、ILI%与流感病毒阳性率变化趋势基本一致(r=0.522,P0.001;r=0.386,P0.001),发病高峰为每年冬春季。不同监测年度,ILI年龄组构成不同(X~2=260.813,P0.001),流感病毒亚型构成亦不同。共报告流感暴发疫情23起,其中10起(43.48%)由甲型H3N2引起,小学报告的疫情最多,为10起(43.48%)。结论 2013-2016年度淄博市流感活动平稳并仍处于低活跃态势。ILI、ILI%与流感病毒阳性率三者高峰基本吻合,证实了淄博市流感监测系统在流感流行趋势预测和暴发疫情预警中的实际作用。
[Abstract]:Objective to analyze the epidemic characteristics of influenza in Zibo city in 2013-2016. Methods the surveillance data of influenza cases were collected from the Chinese Influenza Surveillance Information system in Zibo City in 2013-2016. Results 21,182 influenza-like cases were reported and the percentage of influenza-like cases was 2.44.3 in Zibo city in 2013-2016. The percentage of ILI% was 2.30% and 2.38%, respectively. A total of 4,459 ILI samples were detected. Of these, 510 were positive for influenza viruses. The positive rate is 11.44. ILI% is basically consistent with the trend of influenza virus positive rate. The peak of the incidence is in winter and spring every year. The age group of different surveillance years has different composition of XY2O2C260.813P0.001, and the composition of influenza virus subtype is also different. A total of 23 outbreaks of influenza have been reported. Among them, 10 cases (43.48) were caused by A / H _ 3N _ 2, and 10 cases (43.48) were reported in primary school. Conclusion the influenza activity in Zibo City in 2013-2016 is stable and is still in a low active situation. The positive rate of influenza virus basically coincides with the peak of influenza virus positive rate. The actual function of the influenza surveillance system in Zibo City is confirmed in the prediction of influenza epidemic trend and outbreak warning.
