摘要
H5N1高致病性禽流感是人、禽和其它哺乳动物共患的一种新发传染病,近年禽间疫情波及范围越来越大,人间疫情呈地方性流行趋势。发病人群年龄偏低、病死率高。禽流感病毒有可能变异成一种即有高致病性又有人流感病毒高传播性特点的新型流感病毒,构成越来越严峻的大流行威胁。本文着重就流行病学、病原学及防制对策方面的相关进展进行综述。
Human, birds and other mammals can be infected by avian influenza A ( H5N1 ) virus. Bird infections spread among continents in the last 2 years. Human infections become endemic in certain areas, characterized with young patients and high mortality. An unprecedented epizootic avian influenza A ( H5N1 ) virus that was highly pathogenic has crossed the species barrier in Asia to cause many human fatalities and posed an increasing pandemic threat. This summary describes the features of human infection with influenza A ( H5N1 ) in epidemiology and etiology and reviews recommendations for prevention.
