In 1979, epidemics of influenza occurred in pigs in Belgium from which were isolated strains of influenza A (Hsw1N1) virus antigenically closely related to Hsw1N1 strains previously isolated from ducks in North America and the Federal Republic of Germany. This finding is considered as the first supportive evidence that an influenza A virus in an avian species might have been transmitted to mammals.
1979年,比利时猪群中暴发了流感,从病猪体内分离出了甲型(Hsw1N1)流感病毒毒株,其抗原性与先前在北美和德意志联邦共和国从鸭群中分离出的Hsw1N1毒株密切相关。这一发现被视为首个支持鸟类中的甲型流感病毒可能已传播给哺乳动物的证据。
