遥远的东北,伴随2005年初冬的第一场雪,高致病性禽流感的来势似乎比寒流更猛一些,以H5N1型病毒为主的禽间疫情高度活跃,抗原变异重组,对人群构成严重威胁,全球迄今已确诊150多例H5N1病例,死亡高达51%。病毒随候鸟迁徙,穿城越国地远程飞散似乎刚刚拉开序幕,一场严峻的病毒阻击战,虽不见硝烟,却异常艰难。 In the far northeast, accompanying the first snow in the early winter of 2005, the emergence of HPAI appears to be more violent than that of the cold. The outbreak of H5N1 virus-based poultry is highly active. Antigen variation and recombination have serious consequences for the population Threats, so far the world has confirmed more than 150 cases of H5N1 cases, up to 51% of deaths. Viruses migrating with the migratory birds, wearing the Vietnamese off the country seems to have just kicked off the remote, a severe virus blockade, although no smoke, but unusually difficult.
