Wildlife Monographs, Volume 225, Issue 1, September 2026.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.

Viruses, 2023 High pathogenicity avian influenza (HPAI) viruses of clade 2.3.4.4 H5Nx have been circulating in poultry and wild birds worldwide since 2014. In South Korea, after the first clade 2.3.4.4b H5N1 HPAI viruses were isolated from wild birds in October 2021 ...

Between‐species contagion drives HPAI transmission and mass mortality in seabirds
Journal of Animal Ecology, Volume 95, Issue 8, Page 1488-1503, August 2026.Modelling the unprecedented avian panzootic caused by High‐Pathogenicity Avian Influenza (HPAI) across the Northeast Atlantic gannet breeding metapopulation, we estimated 28% (95% CI: 21%–34%) HPAI‐related mortality. Large‐scale outbreak initiation was best explained by external infection sources, most likely, other seabird species.

Highly pathogenic avian influenza H5N8 Clade 2.3.4.4B virus in Uganda, 2017
Infection, Genetics and Evolution, 2018 In early January 2017, outbreaks of H5N8 highly pathogenic avian influenza (HPAI) were reported for the first time in wild and domestic birds along the shores and on some islands of Lake Victoria, in central-southern Uganda. Our whole-genome phylogenetic analyses revealed that the H5N8 viruses recovered from the outbreak in Uganda belonged to genetic ...

Emergence of Highly Pathogenic Avian Influenza A Virus (H5N1) of Clade 2.3.4.4b in Egypt, 2021–2022
Pathogens, 2023 Wild migratory birds have the capability to spread avian influenza virus (AIV) over long distances as well as transmit the virus to domestic birds. In this study, swab and tissue samples were obtained from 190 migratory birds during close surveillance in Egypt in response to the recent outbreaks of the highly pathogenic avian influenza (HPAI) H5N1 ...

Avian influenza overview December 2022 – March 2023
EFSA Journal, 2023 Between 3 December 2022 and 1 March 2023 highly pathogenic avian influenza (HPAI) A(H5N1) virus, clade 2.3.4.4b, was reported in Europe in domestic (522) and wild (1,138) birds over 24 countries. An unexpected number of HPAI virus detections in sea birds

Zoonoses and Public Health, Volume 73, Issue 5, Page 439-450, August 2026.ABSTRACT Introduction Highly pathogenic avian influenza (HPAI) H5N1, clade 2.3.4.4b is a global threat causing widespread outbreaks on poultry farms and high mortality among wild bird populations in Canada. Wild aquatic birds are generally recognised as key reservoir hosts for avian influenza viruses (AIV's).

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.HPAI H5N1 was confirmed in 22 South Polar Skuas and one Kelp Gull on Dismal and Horseshoe Islands, Marguerite Bay, Western Antarctic Peninsula in early 2025, with high mortalities consistent with global trends. Rapid antigen tests showed 90% agreement with rRT‐PCR, supporting their utility for early detection in remote environments.

Novel Avian Influenza A(H5N6) Virus in Wild Birds, South Korea, 2023
Emerging Infectious DiseasesWe isolated novel reassortant avian influenza A(H5N6) viruses containing genes from clade 2.3.4.4b H5N1 virus and low pathogenicity avian influenza viruses in carcasses of whooper swans and bean geese in South Korea during December 2023.
