An influenza A virus isolated from a duck during a recent surveillance study on commercial poultry from the People's Republic of China and the New Territories, Hong Kong, was shown to possess Hswl antigens related to that of the swine (Hsw1N1) influenza virus. The isolation of an Hsw1N1 influenza virus from ducks indicates that avian species, as well as pigs, may serve as a reservoir of this potential pathogen for humans. The virus was avirulent for ducks, turkeys, chickens, and pigs.
在近期对中华人民共和国和中国香港新界商业家禽进行的监测研究中，从一只鸭子身上分离出的甲型流感病毒被证明具有与猪（Hsw1N1）流感病毒相关的Hsw1抗原。从鸭子身上分离出Hsw1N1流感病毒表明，禽类以及猪可能是这种对人类具有潜在威胁的病原体的宿主。该病毒对鸭子、火鸡、鸡和猪无致病性。
