摘　　要：目的掌握2009年甲型H1N1流感大流行后,河南省流感的季节性特征和流行毒株变化特征,为防控流感提供数据支持。方法运用流行病学描述性分析方法,对2010年-2015年河南省22家国家级流感监测哨点医院的流感样病例监测结果进行数据分析。结果河南省具有明显的流感冬春季节性,多数年份有秋季小高峰;近几年流行毒株为B型、季节性H3和新甲H1交替出现,每个季节一般由单一的血清型主导;新甲H1流感在2009年大流行之后,呈现季节性流行。结论河南省流感多数年份呈双峰流行,每个流行年度有2个或3个血清型(毒株)共同流行,新甲H1型已经替代此前流行的季节性H1型呈季节性流行;ILI就诊比例不宜单独作为反映流感流行趋势的指标。Objective This study aimed to learn the seasonal pattern and the characteristics of the pandemic strain in Henan province after the influenza A （H1N1） pandemic in 2009, and to provide data support for the flu prevention. Methods Descriptive epidemiological method was applied to analyze the surveillance data of influenza-like cases from 22 national influenza surveillance sentinel hospitals in Henan province during 2010-2015. Results Flu cases peaked in winter and spring and there was a small peak in autumn of most years in Henan. Pandemic strains appeared alternately among type B, seasonal H3 and new A （H1）, with each season dominated by a single serotype. New A （H1） flu was a seasonal epidemic after 2009. Conclusion In most years in Henan province there were bimodal epidemic. Each year there were two or three dominant strains. New A （H1） has replaced previous seasonal H1.
