目的了解安徽省流感流行状况,为流感预警提供依据。方法用流感快速诊断试剂筛选标本,采用组织培养法分离流感病毒。结果检测标本330份,阳性102份,其中甲型流感病毒1份,B型101份。组织培养法分离流感病毒检测标本330份,红细胞凝集反应阳性120份。经血凝抑制试验鉴定:甲型1株,B型119株,B型株为B(victoria)系。结论2006年春季安徽省流感流行以B型(victoria)为主,同时存在甲型株。由于人群对B(victoria)系流感流行株抗体水平普遍较低,易引起流感流行。
Objective To understand the prevalence of influenza in Anhui Province and provide basis for early warning of flu. Methods The samples were screened by rapid diagnostic reagent for influenza and the influenza virus was isolated by tissue culture. Results 330 samples were detected, 102 were positive, including 1 influenza A virus and 101 B virus. Tissue culture method was used to separate 330 influenza virus samples and 120 hemagglutination positive. The hemagglutination inhibition test identified: a strain of 1, 119 strains of B, B strains of B (victoria) line. Conclusion The prevalence of influenza in Anhui Province in spring 2006 mainly belonged to type B (victoria), with the presence of type A strain. As the crowd of B (victoria) influenza strains generally lower antibody levels, easy to cause the flu epidemic.
