世?要求各地采取紧急行动销毁这批样本。 h2n2病毒曾在1957至1958年感染人类，直至1968年才最终消失，由于h2n2病毒可在人与人之间传播，而人口中相当部分对此病毒都没有免疫力。 - Although human - to - human transmission is inefficient , all influenza viruses have the ability to change genetically , and scientists are concerned that the h5n1 virus could one day be able to spread easily from one person to another . because the virus does not commonly infect humans , there is little or no immune protection against it in the human population . if the h5n1 virus could spread easily from person to person , an influenza pandemic could occur
禽流感可以从活鸟身上感染人类，现时人传人的效率虽然不大，但所有流感病毒都有出现基因变异的能力，因此科学家都很关注h5n1病毒终有一天会轻易地在人与人之间传播而且因为这种病毒感染在人类身上并不常见，人体抵抗这种病毒的免疫力极低，甚至根本没有免疫力，一旦病毒能够轻易地在人与人之间传播，就会出现一场流感大流行。
