Variable transmission efficiency of mammalian origin HPAI D1.1 H5N1 strains in ferrets

2026-05-08

Abstract excerpt

Highly pathogenic avian influenza H5N1 2.3.4.4b genotype D1.1 lineage continues to predominate in the United States wild bird population and has spilled over into dairy cattle three independent times. To assess the transmission risk of this sublineage, we performed direct-contact transmission experiments for three distinct D1.1 strains in ferrets. Two of these strains were isolated from humans and one from a letha...
