|flu virus;禽流感病毒
禽流感病毒(Avian Influenza Virus,AIV)是甲型流感病毒(Influenza A virus)的一种亚型,主要感染禽类,但也可能通过跨物种传播感染人类及其他哺乳动物。该病毒属于正粘病毒科(Orthomyxoviridae),其基因组由8条单链RNA片段组成,表面分布着血凝素(HA)和神经氨酸酶(NA)两种糖蛋白刺突,不同HA和NA蛋白的组合形成多种亚型(如H5N1、H7N9等)。
根据世界卫生组织(WHO)的定义,禽流感病毒可分为低致病性(LPAI)和高致病性(HPAI)两类。高致病性毒株(如H5N1)在禽类中致死率可达100%,并可通过直接接触感染禽类的分泌物或污染环境传播给人类。中国国家卫生健康委员会指出,人类感染后可能出现发热、咳嗽、急性呼吸窘迫综合征等严重症状。
《柳叶刀》期刊的研究显示,H5N1亚型自1997年首次感染人类以来,已导致全球超过50%的感染者死亡,但由于其尚未获得持续人际传播能力,目前主要威胁集中于禽类养殖业和密切接触者群体。世界动物卫生组织(WOAH)建议通过加强禽类监测、扑杀感染群体、研发重组疫苗等综合措施控制疫情扩散。
avian influenza virus(禽流感病毒)是A型流感病毒(Influenza A virus)的一种,主要感染禽类,也可跨物种传播至人类和其他哺乳动物。以下从多个角度详细解释该术语:
avian influenza virus(缩写为AIV)是引起禽流行性感冒(avian influenza, AI)的病原体,属于正黏病毒科。其基因组由8个单链RNA片段组成,表面含有两种关键糖蛋白:血凝素(Hemagglutinin, H)和神经氨酸酶(Neuraminidase, N)。根据H和N蛋白的抗原性差异,AIV可分为多种亚型,如H5N1、H7N9等。
AIV可通过直接接触或空气传播感染人类。1997年香港首次报道人感染H5N1致死病例,2013年后H7N9亚型在中国多次引发人际感染。人类感染后可能出现高热、肺炎、多器官衰竭等症状,死亡率较高。
AIV被认为是人流感病毒的基因库,若与人类流感病毒发生基因重组,可能引发全球大流行。目前防控措施包括扑杀感染禽类、加强病毒监测和研发疫苗(如针对H5N1和H7N9的灭活疫苗)。
avian influenza virus是禽类烈性传染病的主要病原体,具有高变异性和跨物种传播风险。其亚型H5N1、H7N9等对人类健康构成严重威胁,需通过国际合作加强监测与防控。更多信息可参考世界卫生组织(WHO)或农业部门的最新指南。
