Role for migratory wild birds in the global spread of avian influenza [PDF]

, 2016
Avian influenza viruses affect both poultry production and public health. A subtype H5N8 (clade 2.3.4.4) virus, following an outbreak in poultry in South Korea in January 2014, rapidly spread worldwide in 2014–2015.

Genetic Characterization of Highly Pathogenic Avian Influenza A(H5N8) Virus in Pakistani Live Bird Markets Reveals Rapid Diversification of Clade 2.3.4.4b Viruses

Viruses, 2021
The highly pathogenic (HPAI) avian influenza A(H5N1) viruses have undergone reassortment with multiple non-N1-subtype neuraminidase genes since 2008, leading to the emergence of H5Nx viruses.

Association of wild bird densities around poultry farms with the risk of highly pathogenic avian influenza virus subtype H5N8 outbreaks in the Netherlands, 2016

Transboundary and Emerging Diseases, 2020
Highly pathogenic (HP) avian influenza viruses (AIV) can spread globally through migratory birds and cause massive outbreaks in commercial poultry. AIV outbreaks have been associated with proximity to waterbodies, presence of waterfowl or wild bird cases

Feathers and flu: identifying data gaps in avian influenza host dynamics to prioritize wildlife conservation Plumas y gripe: identificación de datos faltantes en la dinámica de hospedadores de la influenza aviar para priorizar la conservación de la vida silvestre

Wildlife Monographs, EarlyView.
We describe the host response continuum for highly pathogenic avian influenza viruses (HPAIV), including the continuum of host responses to HPAIV infection and exposure based on the primary axis of host competence, ability to infect other hosts, and host vulnerability.

Evolutionary Dynamics of H5 Highly Pathogenic Avian Influenza Viruses (Clade 2.3.4.4B) Circulating in Bulgaria in 2019–2021

Viruses, 2021
The first detection of a Highly Pathogenic Avian Influenza (HPAI) H5N8 virus in Bulgaria dates back to December 2016. Since then, many outbreaks caused by HPAI H5 viruses from clade 2.3.4.4B have been reported in both domestic and wild birds in different

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

Influenza 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

Zoonoses 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

Marine 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.

A Lethal Case of Natural Infection with the H5N8 Highly Pathogenic Avian Influenza Virus of Clade 2.3.4.4 in a Mandarin Duck

, 2022
Recent global outbreaks of highly pathogenic avian influenza viruses (HPAIVs) of the H5N8 subtype in poultry and wild birds have raised concerns about animal and human health, particularly after its first evidence of zoonotic transmission from birds to ...

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

Advanced 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
