H5N1高致病性禽流感病毒的危害及生态问题

高致病性禽流感(HPAI)H5N1病毒亚型已对人类健康、养殖业发展、野生鸟类及生态环境带来极大危害,引起国内外广泛关注。研究发现,禽流感病毒通过发生重组或者突变,可产生感染人类或其他生物的新病毒亚型,或产生更高的致病性,而人类亦具有丰富的与H5N1结合的受体。对候鸟迁徙停歇地禽流感调查表明,湿地、湖泊可能是HPAI病毒存活、散播的疫源地,病毒可随着鸟类的迁徙到处传播。因此,野生鸟类及其赖以生存的主要湿地环境处于感染HPAI的风险之中。

The Threat of Highly Pathogenic Avian Influenza H5N1 and Its Ecological Basis

Highly Pathogenic Avian Influenza(HPAI) H5N1 is paid more attention by the human society because it has seriously influenced on the human life,farming,wild birds and ecological environments.It was found currently that AI viruses may affect human and other wild animals by the new subtype or with higher pathogenic through viruses recombination or mutation because people have this H5N1 receptors.AIV surveillance conducted around migratory birds habitats revealed that wetlands,lakes are most possibly the natural origin of AI disease because they may maintain the viruses and spread them through wild bird migration,on the country,these wetlands and their wild birds may therefore face the risk of HPAI.
