摘要

自2024年春季以来，在美国发现了高致病性禽流感（HPAI） H5N1进化枝2.3.4.4b的新基因型。这些高致病性H5N1基因型在家禽和奶牛场造成了前所未有的多州暴发以及人类感染。在此，我们讨论了此次疫情的现状，并强调需要在大流行前做好准备，以控制美国家禽和奶牛场的高致病性H5N1。

Highly pathogenic avian influenza H5N1 in the United States: recent incursions and spillover to cattle.

Since Spring 2024, new genotypes of highly pathogenic avian influenza (HPAI) H5N1 clade 2.3.4.4b have been identified in the United States (US). These HPAI H5N1 genotypes have caused unprecedented multi-state outbreaks in poultry and dairy farms, and human infections. Here, we discuss the current situation of this outbreak and emphasizes the need for pre-pandemic preparedness to control HPAI H5N1 in both poultry and dairy farms in the US.
