The highly pathogenic H5N1 virus found in U.S. dairy cattle has some characteristics that could enhance infection and transmission among mammals

A highly pathogenic H5N1 influenza virus is spreading in U.S. dairy cattle and has been transmitted to other species, including humans, probably through contaminated milk. Understanding how the virus spreads among cattle and its potential for mammalian adaptation and airborne transmission is crucial for effective outbreak control and public health safety.
