Surveillance of Migratory Shorebirds and Seabirds in 2024 in Australia Reveals Incursions of a Diversity of Low Pathogenicity Avian Influenza Viruses, but Not High Pathogenicity Avian Influenza H5N1

open access: yesInfluenza and Other Respiratory Viruses, Volume 20, Issue 6, June 2026.
ABSTRACT Background The current panzootic of high pathogenicity avian influenza (HPAI) H5N1 has been catastrophic for wildlife, and following substantial geographic spread, clade 2.3.4.4b is found in every region aside from Oceania. Herein, we report the results of our third year of targeted surveillance of incoming migratory seabirds and shorebirds ...

Longitudinal Surveillance of Influenza A Virus Exposure in Wild Boars (Sus scrofa) in Spain (2015–2023): Serologic and Virologic Evidence of Subtype Infections and H5N1 Spillover Risk

open access: yesZoonoses and Public Health, Volume 73, Issue 3, Page 191-204, May 2026.
ABSTRACT Introduction Influenza A viruses (IAVs) are responsible for respiratory infections in a wide range of species, including birds, swine and humans. The role of wild boar (Sus scrofa) in IAV epidemiology remains underexplored. Here, we present a longitudinal serologic and virologic surveillance study of wild boars in Spain from 2015 to 2023 ...

Sharing Is Caring?—Pathogens and Pathogen‐Specific Antibodies in Arctic Endemic Seal Species and the Newly Sympatric Harbor Seals in Kongsfjorden, Svalbard

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission.

Highly Pathogenic Avian Influenza A(H5N8) Clade 2.3.4.4b Viruses in Satellite-Tracked Wild Ducks, Ningxia, China, 2020

open access: yesEmerging Infectious Diseases, 2022
During October 2020, we identified 13 highly pathogenic avian influenza A(H5N8) clade 2.3.4.4b viruses from wild ducks in Ningxia, China. These viruses were genetically related to H5N8 viruses circulating mainly in poultry in Europe during early 2020 ...

Evolution of H5N1 Cross‐Species Transmission: Adaptive Mutations Driving Avian‐to‐Human Infection

open access: yesAdvanced Genetics, Volume 7, Issue 1, March 2026.
This review synthesizes current knowledge on the molecular mechanisms underpinning H5N1's host adaptation, focusing on key mutations in viral proteins. Critical mutations are discussed in detail, highlighting their roles in altering receptor specificity, promoting antiviral resistance, and expanding viral tropism. The review underscores the urgent need

Pathogenesis of novel reassortant avian influenza virus A (H5N8) Isolates in the ferret [PDF]

open access: yes, 2015
Outbreaks of avian influenza virus H5N8 first occurred in 2014, and spread to poultry farms in Korea. Although there was no report of human infection by this subtype, it has the potential to threaten human public health.
