目的:为了解盘锦地区流感流行情况,对2007年-2009年流感的病原学监测结果进行分析,便于为今后的流感防控提供科学依据。方法:将流感监测点送检的咽拭子标本,用MDCK细胞进行流感病毒分离,用血凝抑制试验方法(HI)进行病毒型别鉴定。结果:2007年-2009年,流感病毒分离率分别为:12.5%、2.4%、2.78%。结论:年2007年-2009年流感病毒的优势毒株分别是:Bv、A3、A1,发病高峰分别是春季和秋冬季节。
OBJECTIVE: To understand the prevalence of influenza in Panjin region, the etiological surveillance results of influenza from 2007 to 2009 were analyzed to provide a scientific basis for future prevention and control of influenza. Methods: The throat swab specimens were collected from the influenza surveillance sites, and the influenza viruses were isolated from MDCK cells and the virus type was identified by HI test. Results: From 2007 to 2009, the isolation rates of influenza viruses were 12.5%, 2.4% and 2.78% respectively. Conclusion: The dominant strains of influenza virus from 2007 to 2009 are: Bv, A3 and A1, respectively. The onset peak is spring and autumn and winter respectively.
