"The viruses that are in circulation now are much more mammalian-like than the ones circulating in 1997," says Kawaoka, an internationally recognized authority on influenza.
这位国际上公认的流感权威认为，“禽流感病毒现在的传播状态比1997年时更接近于哺乳动物。”
According to Kawaoka, the avian virus can be at home in the lungs of humans and other mammals as the cells of the lower respiratory system have receptors that enable the virus to establish itself.
根据Kawaoka的说法，由于下呼吸道系统的细胞中具有使禽流感病毒自我重建的受体，其更适应于人类和其它哺乳动物的肺脏。
