Persistence and spillback of mammal-adapted H5N1 genotype B3.2 viruses among South American seabirds and marine mammals

2025-11-04

Abstract excerpt

<title>Abstract</title> <p>The arrival of H5N1 clade 2.3.4.4b genotype B3.2 in South America marks an unprecedented geographic expansion of highly pathogenic avian influenza viruses. The continent remains the only region with sustained H5N1 transmission in wild marine mammals. To investigate the evolution of H5N1 in this novel context, we conducted genomic surveillance in marine wildlife along the northern Patago...
