A genomic and movement-network study finds that live dairy cattle movement, rather than wild or domestic birds, was the main driver of H5N1 B3.13 spread across US states. Most interstate transmission happened before the April 2024 movement restrictions.
Within-state spread continued afterward, driven by local cattle network density.
The findings point to cattle movement controls as the key lever for limiting dairy herd infections, which affects milk supply risk. The study has no direct price effect.
