目的:了解福州市2006年-2010年流感流行概况,为更好地预防和控制流感流行提供科学依据。方法:通过全国流感监测网络系统,收集2006年-2010年度福州市流感和流感样病例(Influenza Like Illness,ILI)资料。用MD-CK细胞对送检的流感样病例的咽拭子标本进行病毒分离,用微量血凝集抑制试验(HIA)进行病毒型别鉴定。结果:2006年-2010年流感样病例占门急诊病例总数的比例平均分别为2.22%、2.34%、1.36%、2.30%、2.28%,2006年-2010年间流感样病例年龄构成,以0～岁组最高,其次为5～岁组,15岁以下者平均占总病例数的80%以上。2006年-2008年间福州市的流感优势毒株分别为B型流感病毒、H3N2亚型流感病毒和B型流感病毒。2009年H1N1、H3N2、B三种亚型流感病毒均有分离到,自8月份以后,甲型H1N1流感成为优势流行株。2010年1月～3月仅分离到B型流感病毒和甲型H1N1亚型流感病毒。结论:2006年-2010年福州市先后出现B型、H3N2亚型、甲型H1N1流感病毒的流行,流感病毒流行株发生了交替变换。
Objective: To understand the general situation of influenza in Fuzhou City from 2006 to 2010, and to provide a scientific basis for better prevention and control of influenza pandemic. Methods: The Influenza Like Illness (ILI) data of Fuzhou from 2006 to 2010 were collected through the National Influenza Surveillance Network System. Throat swab samples of the flu-like cases were tested for virus isolation using MD-CK cells and virus type identification was performed using a microagglutination inhibition assay (HIA). Results: The average number of flu-like cases among emergency departments in 2006 and 2010 was 2.22%, 2.34%, 1.36%, 2.30% and 2.28%, respectively. The age of influenza-like cases from 2006 to 2010 was from 0 to The highest group, followed by 5 ~ group, the average age of 15 years accounted for more than 80% of the total number of cases. Influenza strains in Fuzhou from 2006 to 2008 were Influenza B virus, H3N2 influenza virus and influenza B virus, respectively. 2009 H1N1, H3N2, B three subtypes of influenza viruses have been isolated, since August, Influenza A H1N1 influenza became the dominant strain. From January to March 2010, only type B influenza virus and type A H1N1 subtype influenza virus were isolated. Conclusion: The epidemic of influenza A and B (H3N2) and influenza A (H1N1) viruses occurred successively in Fuzhou from 2006 to 2010, and the epidemic strains of influenza viruses alternated.
