【摘要】：目的了解上海市闵行区2013—2016年人群流感流行特征,为流感防控提供科学参考依据。方法收集2013—2016年闵行区流感监测网流感样病例(influenza like illness,ILI)数据和实验室病原学检测数据,分析流感流行特征。结果 2013—2016年监测到流感样病例数为37 738例,流感样病例数占门诊人数的月平均构成比为0.90%。共采集标本4 094份,分离到的各型流感病毒857份,总分离率为20.93%。2013年优势株以季节性A(H3N2)型为主,2014年以B(Yamagata)型和季节性A(H3N2)型共同流行。2015年夏季高峰以季节性A(H3N2)型为主,2015年12月至2016年4月的冬春季高峰分别以新型甲型H1N1型(H1N1 pdm09)和B(Victoria)型为共同流行。2016年冬季高峰又以季节性A(H3N2)型流行为主。ILI就诊百分比(ILI%)与流感病毒阳性检出率呈正相关,Spearman秩相关分析结果显示二者高度相关(rs=0.460,P0.05)。结论闵行区流感大致分为冬春季和夏季两个流行高峰,流感病毒优势株交替出现并呈现一定规律,ILI流行特征与流感病毒活动趋势基本一致。
[Abstract]:Objective to understand the epidemic characteristics of influenza in the population of Minhang District in Shanghai from 2013 to 2016, and to provide a scientific reference for influenza prevention and control. Methods the data of like infection and laboratory etiology were collected from the influenza surveillance network of Minhang District from 2013 to 2016. Results in 2013-2016, the number of influenza like cases was 37,738, and the average proportion of influenza cases to outpatients was 0.900.A total of 4,094 samples were collected and 857 influenza viruses were isolated. The total isolation rate was 20.93.The dominant strain in 2013 was seasonal AH3N2, and in 2014 it was common epidemic of BGW Yamagata and seasonal AH3N2. The summer peak of 2014 was mainly seasonal AH3N2, and the winter spring peak from December 2015 to April 2016 was the new type of A H1N1, respectively. In 2016, the winter peak was seasonal AH3N2). The percentage of ILI was positively correlated with the positive detection rate of influenza virus. The results of Spearman rank correlation analysis showed that there was a high correlation between the two types. Conclusion Minhang has a high correlation with the positive rate of influenza virus. District influenza is roughly divided into two epidemic peaks: winter, spring, and summer. The dominant strains of influenza virus appeared alternately and showed a certain regularity. The epidemic characteristics of ILI were basically consistent with the trend of influenza virus activity.
