【摘要】：目的了解黄浦区2009-2014年间流感流行特征,为流感防控工作提供科学依据。方法根据国家流感监测方案,收集本区流感监测点流感样病例(ILI)相关诊室就诊情况以及ILI就诊情况,对部分病例进行采样开展病原学监测,使用RT-PCR方法进行流感病毒亚型鉴定,阳性标本用MDCK细胞进行病毒分离。结果 2009-2014年黄浦区各周ILI%为0.27%~1.54%之间,三级医院周ILI%明显低于二级医院。检测流感样病例咽拭子标本8 315份,检出流感病毒阳性2 552份,阳性率为30.69%。结论本区流感发病主要集中在冬春季,夏季偶有流行。流感病毒优势亚型交替频繁,2009年本地区优势流行株为甲型H1N1,非流行年份优势流行株为H3和B型。
[Abstract]:Objective to understand the epidemic characteristics of influenza in Huangpu District from 2009 to 2014, and to provide scientific basis for influenza prevention and control. Methods according to the National Influenza Surveillance Program. To collect the clinic visits and ILI visits of influenza like cases at the influenza surveillance sites in this district, and to sample some cases to carry out etiological monitoring. RT-PCR method was used to identify influenza virus subtypes. The positive samples were isolated by MDCK cells. Results the ILI% was between 0.27% and 1.54% in each week of Huangpu District from 2009-2014. The ILI% was significantly lower in the third class hospital than in the second class hospital. 8 315 throat swabs were detected and 2 552 influenza virus positive samples were detected. The positive rate is 30.69B. ConclusionInfluenza occurs mainly in winter and spring, and occasionally in summer. The dominant influenza virus subtype alternates frequently, and in 2009, the dominant epidemic strain in this area is H1N1. The dominant epidemic strains were H3 and B in non-epidemic years.

【正文快照】： 流行性感冒(influenza)简称为流感,是由流感病毒导致的急性呼吸系统疾病。由于流感病毒经常发生抗原变异,传染性大,传播迅速,并且缺乏特异性的抗病毒药物,使流感一直不能得到有效防控。流感也是世界卫生组织(WHO)第一个实行全球性监测的传染病。上海市黄浦区自2004年建立了流
