Emerging Haemagglutinin Mutations in Bovine-origin H5N1 Influenza Viruses from Humans and Cattle Retain Avian Receptor Binding with Increased Stability

2026-08-21

Abstract excerpt

The current H5N1 panzootic has seen an unprecedented host range expansion, including sustained circulation in US dairy cattle, detected in March 2024. By July 2026, infections had been reported on more than 1,150 dairy farms across 19 states. Although the outbreak initially centred in Texas, California has emerged as the principal focus of transmission and accounts for most human infections associated with exposur...
