【摘要】：目的了解上海市松江、闵行地区2011年-2012年人群流感的流行特征。方法收集、汇总上述地区流感监测哨点医院的流感样病例数、就诊人数等进行描述性流行病学分析。对采集的流感样病例咽拭子用荧光定量PCR进行各型流感病毒核酸检测,对核酸阳性标本进行流感病毒培养,并用红细胞凝集抑制试验鉴定流感病毒型和亚型。结果 2年间监测到流感样病例总数为23 572例,流感样病例平均就诊比例为1.12%。采集咽拭子标本2 888份,分离到各型流感毒株870株,2011年优势株为B型,2012年优势株为季节性H3N2与B型共同流行。病毒分离及流行病学监测显示:2011年成人和儿童流感呈年初和年末冬春季高发,2012年则呈现明显的年初冬春季和夏季高发。结论 2011年-2012年上海松江、闵行地区流感流行特点大致为冬春季和夏季高发,新甲型H1N1、B、季节性H3N2呈优势交替流行。
[Abstract]:Objective to investigate the epidemic characteristics of influenza in population in Songjiang and Minhang areas of Shanghai from 2011 to 2012. Methods the number of influenza-like cases and the number of patients in influenza surveillance sentinel hospitals were collected and collected for descriptive epidemiological analysis. The throat swabs of influenza like cases were detected by fluorescence quantitative PCR, the positive samples were cultured, and the influenza virus types and subtypes were identified by erythrocyte agglutination inhibition test. Results the total number of influenza-like cases was 23,572 in the past two years, and the average proportion of influenza like cases was 1.12. A total of 2888 throat swabs were collected and 870 strains of influenza virus strains were isolated. The dominant strain in 2011 was B strain, and the dominant strain was seasonal H3N2 and B type in 2012. Virus isolation and epidemiological surveillance showed that the incidence of influenza in adults and children in 2011 was high at the beginning of the year and the end of the year in winter and spring, and that in 2012 was obviously high in the early winter, spring and summer. Conclusion the epidemic characteristics of influenza in Songjiang and Minhang areas of Shanghai from 2011 to 2012 are generally high in winter, spring and summer, and the new A H1N1 1B and seasonal H3N2 are dominant alternately.
