近期出版的《传染病杂志》(JID)发表的一项最新研究首次报道了致病力较低的禽流感病毒株可从家禽传播至人类;跨物种屏障传播是流感发生潜在流行的重要一步。此前的研究已将重点集中在高致病性禽流感病毒株(如亚洲流行的H5N1)从家禽传播到人类的能力上;新的研究结果显示低致病力的禽流感病毒株 A recent study, published recently by the Journal of Infectious Diseases (JID), for the first time reported for the first time that pathogenic avian influenza strains can be transmitted from poultry to humans; cross-species barrier transmission is an important step toward the potential epidemic of influenza. Previous research has focused on the ability of HPAI strains (such as H5N1 in Asia) to spread from poultry to humans; new findings show that the low-virulent avian influenza virus strain
