H9N2 avian influenza viruses have become globally widespread in poultry over the last two decades and represent a genuine threat both to the global poultry industry but also humans through their high rates of zoonotic infection and pandemic potential. H9N2 viruses are generally hyperendemic in affected countries and have been found in poultry in many new regions in recent years. In this review, we examine the current global spread of H9N2 avian influenza viruses as well as their host range, tropism, transmission routes and the risk posed by these viruses to human health.
在过去的二十年中，H9N2 禽流感病毒已在禽类中在全球范围内广泛传播，它们不仅对全球家禽业构成了真正的威胁，而且由于其高比例的人畜共患感染和大流行潜力，也对人类构成了威胁。H9N2 病毒在受影响的国家通常呈高度地方性流行，并在近年来的许多新地区的家禽中发现。在这篇综述中，我们研究了 H9N2 禽流感病毒的当前全球传播情况，以及它们的宿主范围、嗜性、传播途径以及这些病毒对人类健康构成的风险。
