[目的]了解上海市浦东新区流感流行趋势及病原学特征。[方法]监测点医院每周填写流感样病例(ILI)报表并上报网络,监测点医院每周采集ILI鼻咽试子5~20份送浦东新区疾病预防控制中心进行流感病原检测。[结果]流行病学监测及病原学监测显示,2008年(3月、8月)、2009年(1月、8月、12月)、2010年(9月)的ILI百分率值及ILI流感病毒阳性率均为监测峰值。2008年2月以B(Yam agata)亚型毒株为主,3月以A(H3N2)亚型毒株为主;2008年7月—2009年2月以A(H1N1)亚型毒株为主,2009年7月—8月以A(H3N2)亚型毒株为主,2009年9月—2010年1月以甲型H1N1亚型毒株为主,2010年2月—3月以B(V ictoria)型毒株为主,2010年8月—11月以A(H3N2)型毒株为主。[结论]2008年呈现冬春季和夏秋季的双峰型分布,2009年呈现冬春、夏秋季、冬季延伸至2010年春3峰流行,2010年呈现夏秋季高峰流行。流感毒株亚型循环流行。
[Objective] To understand the epidemic trend and etiological characteristics of influenza in Pudong New Area in Shanghai. [Methods] The hospital of the monitoring point filled out the ILI report weekly and reported it to the network. The monitoring hospital collected 5 ~ 20 ILI nasopharyngeal samples weekly and sent to the Pudong New Area CDC for influenza pathogen detection. [Results] Epidemiological surveillance and etiological monitoring showed that the ILI percentage values in 2009 (January, August and December), 2010 (September) and ILI influenza virus The positive rate is monitoring peak. In February 2008, B (Yam agata) subtype was the main strain, and A (H3N2) subtype was the main one in March. From July 2008 to February 2009, the A (H1N1) subtype was The main strain was A (H3N2) subtype from July to August in 2009. From September 2009 to January 2010, the strain was mainly subtype A (H1N1). In February-March 2010, B (Victoria) type strain, August 2010-November A (H3N2) type-based. [Conclusion] The bimodal distribution of winter, spring and summer and autumn was presented in 2008, showing the winter and spring, summer and autumn in 2009, the winter in spring to 3 peaks in spring 2010 and the peak in summer and autumn in 2010. Influenza virus subtype circulating popular.
