摘　　要：2009年3月墨西哥与美国先后出现甲型H1N1型流感,并在很短时间内席卷全球,世界卫生组织(WHO)将此次全球流感大流行的预警级别提高到5级。目前的研究表明甲型H1N1流感病毒的传染性极强,但是病死率有待确证。此外,病毒特点也尚未明了,本文对甲型流感病毒及其进化特点进行简述,借此为该病的认识提供借鉴。Objective An epidemic outbreak of A HIN1 influenza suddenly occurred in Mexico and America in May 2009, and rapidly spread over more countries throughout the world, then the World Health Organization （WHO） raised the level of influenza pandemic alert to Phase 5. The virus was found with high infectivity and fast spread speed, while no enough evidences existed to confirm the mortality up to now. However, the characteristics of A H1N1 virus had not been elucidated. The new subtype of influenza virus and its evolution were introduced in present paper to supply an reference awareness.
