Mass Mortality of Sea Lions Caused by Highly Pathogenic Avian …
We report a massive mortality of 5,224 sea lions (Otaria flavescens) in Peru that seemed to be associated with highly pathogenic avian influenza A(H5N1) virus infection. The transmission pathway may have been through the close contact of sea lions with infected wild birds.

Highly pathogenic avian influenza A (H5N1) virus outbreak in Peru …
Jun 1, 2024 · The influenza A HPAI (H5N1) outbreak in 2022–2023 had a great impact on both birds and mammals in Peru. According to our study, the H5N1 found in Peru clustered with that in Chilean samples, is a member of the 2.3.4.4b clade, and may have originated in North America.
A Geospatial Perspective Toward the Role of Wild Bird Migrations …
Mar 25, 2025 · The unprecedented global transmission of H5N1 from 2020 onwards further highlighted their role. After 2020, reports of HPAI outbreaks in mammals, including Spanish minks, otters in England, and sea lions in Peru, underscored the environmental persistence of the virus and its transmission across diverse hosts (Nishiura et al., 2023). Whilst ...
Highly Pathogenic Avian Influenza A (H5N1) from Wild Birds, …
We identified highly pathogenic avian influenza A(H5N1) virus clade 2.3.4.4b in wild birds, poultry, and a lion in Peru during November 2022-February 2023 and markers associated with transmission adaptation and antiviral drug resistance.
La expansión de la gripe aviar: un rompecabezas que los …
20 hours ago · Al principio, nadie creía que fuera H5N1, dice Robert Webster, virólogo y profesor emérito del St. Jude Children’s Research Hospital de Memphis, Tennessee, que dirigió uno de los equipos que lo identificaron. Se suponía que un virus con un H5 era un virus de gallina. Pero este H5N1 infectó a 18 personas y mató a seis de ellas.
