[目的]分析2007年福田区中小学校流感暴发的流行特征,评价疾控机构控制措施,为防控提供依据。[方法]对样本采用实时荧光定量PCR检测和MDCK细胞培养法分离病毒,微量血凝抑制实验进行鉴定,汇总整理分析暴发疫情资料。[结果]2007年福田区共报告暴发疫情18起,发病195人,罹患率0.89%～34.8%。4月和6月疫情较高,小学高于中学,18起疫情中15起分离出流感病毒,其中H3N2型13起,B(V)型2起。[结论]疫情全部发生于中小学校,流感病毒的分型构成与流感的日常监测所得的结果一致,但流感暴发疫情的病原溯源率未达100%。今后应加强学校流感防治,重视标本收集和实验检测工作。
[Objective] To analyze the epidemic characteristics of influenza outbreak in primary and secondary schools in Futian district in 2007, evaluate the control measures of CDC institutions and provide basis for prevention and control. [Methods] The samples were isolated by real-time fluorescence quantitative PCR and MDCK cell culture, and the micro-hemagglutination inhibition test was used to identify and summarize and analyze the outbreak data. [Results] In 2007, a total of 18 cases of outbreaks were reported in Futian District, with a total of 195 cases and an attack rate of 0.89% to 34.8%. The outbreaks in April and June were higher than those in secondary schools. In the 18 outbreaks, 15 out of the 18 outbreaks of influenza virus were isolated, of which 13 were H3N2 type and 2 were type B (V). [Conclusion] All the outbreaks occurred in primary and secondary schools. The typing of influenza virus was consistent with the results of routine surveillance of influenza. However, the origin of the outbreak of influenza was less than 100%. In the future, we should strengthen the prevention and control of influenza in schools and pay attention to the collection and experimental testing of specimens.
