摘要: 目的 分析成都某医院2011~2013 年流感监测结果,探索流感流行特征及规律,为制订流感防治策略提供依据。方法 将内科门诊、发热门诊、内科急诊和儿内科门诊设置为监测诊室,按照国家流感监测方案开展监测工作,并对监测结果进行分析。结果 登记报告流感样病例就诊百分比(ILI%)2011 年为1.95%,2012 年为1.24%,2013 年为2.70%。2011~2013 年832 份ILI 标本中流感病毒核酸阳性率为13.82%,其中各亚型流感病毒构成比分别为:B 型19.13%、季节性A(H1N1)型0.87%、A(H3N2)型15.62%和甲型H1N1 流感64.35%。ILI 在冬春季节出现就诊高峰,与标本核酸检测阳性率高峰时间呈正相关(r=0.457,P<0.001);ILI 年龄组构成比以5~15 岁组最高,各年龄组核酸检测阳性率差异有统计学意义。结论 ILI 流行强度与流感病毒活动趋势一致。流感防治工作需要在冬春以及夏季加强。需注重各年龄层的采样比例,减少采样人群分布不均衡导致的监测结果差异。

Abstract:

Objective To analyze the epidemic feature and regulation on influenza from 2011 to 2013,and provide scientific basis for influenza prevention. Methods The medical clinic, fever clinic, emergency department and children clinic were set up as monitor clinic, surveillance work were carried out in accordance with national influenza surveillance programme and the results were analyzed. Results The registration percentage of influenza like illness in outpatients (ILI%) in 2011, 2012, 2013 were 1.95%, 1.24% and 2.70%, respectively. The positive rate of nucleic acid of influenza virus in 832 ILI specimens was 13.82% and the constituent ratio of subtype B, seasonal A (H1N1), A (H3N2), A (H1N1) were 19.13%, 0.87%, 15.62% and 64.35%. The visiting peak of ILI occurred in winter and spring and correlated with the peak time of positive rate of nucleic acid (r=0.457, P<0.001). The highest constituent ratio of age in ILI was 5~15 years old and there were significant differences in positive rate of nucleic acid among all age groups. Conclusion The epidemic strength of ILI was consistent with the activity trend of influenza virus and the prevention of influenza should be strengthened in winter-spring and summer. Moreover, more attention should be paid on sampling ratio in each age groups to reduce the surveillance differences caused by uneven distribution of sampling population.
