| 摘 要： | 目的分析衡阳市2009-2011年度流感病毒流行情况,了解病毒毒株的型别及变化特点,为预防和控制流感提供科学依据。方法采集流感样病例（ILI）的鼻咽拭子标本,采用狗肾细胞（MDCK）进行病毒分离和（或）RT-PCR方法检测病毒核酸,分离到的毒株采用血凝抑制实验（HI）进行流感病毒型别鉴定。结果 2009年3月-2011年2月共采集2 682份ILI咽拭子标本,采用病毒分离887份,分离到毒株116株,分离阳性率13.08%,其中季节性A（H1N1）亚型31株,季节性A（H3N2）亚型35株,B-victoria系36株,B-yamagata系6株,新甲型H1N1 8株;采用核酸检测2 143份,核酸阳性737份,阳性率34.39%,其中新甲型H1N1 543份,季节性A型146份,季节性B型48份。结论 2009年3月-2011年2月流感毒株各型别阶段性交替形成优势株。全年皆有流感样病例,夏季高峰较明显。2009年是流感大流行年,9月新甲型H1N1的流行成为主导,并在11-12月份达到流行高峰。为更好防控流感,及时掌握流行趋势,仍需加强监测。
