科学家警告说,H5N1禽流感是人类不易传播的一种突变。 Scientists warn that H5N1 bird flu is one mutation away from easily spreading among humans.

Scripps研究所的研究人员发表在《科学》杂志上说,禽流感H5N1病毒只是一种与有效感染人类无关的突变。 Researchers from the Scripps Research Institute published in Science that the avian H5N1 virus is merely one mutation away from efficiently infecting humans. 这种突变涉及改变某一地点的氨基酸,有可能使病毒与人体细胞结合。 This mutation involves changing an amino acid at a specific site, potentially allowing the virus to bind to human cells. 虽然病毒目前感染鸟类,有时也感染人类,但这种转变可能使病毒在人类中高度可传播,从而形成流行病风险。 While the virus currently infects birds and occasionally humans, this shift could make it highly transmissible among humans, posing a pandemic risk.
