Massive outbreak of Influenza A H5N1 in elephant seals at Península Valdés, Argentina: increased evidence for mammal-to-mammal transmission

2024-06-01

Abstract excerpt

<h4>ABSTRACT</h4> H5N1 high pathogenicity avian influenza (HPAI) viruses of the clade 2.3.4.4b have killed thousands of marine mammals in South America since 2022. In October 2023, following outbreaks in sea lions in Argentina, we recorded unprecedented mass mortality (∼17,000 individuals) in southern elephant seals ( Mirounga leonina ) at Península Valdés. Seal pups were disproportionately affected. Adult seals...
