Highly Pathogenic Avian Influenza A(H5N1) Virus–Induced Mass Death of Wild Birds, Caspian Sea, Russia, 2022

Emerging Infectious Diseases, 2023
In May 2022, we observed a substantial die-off of wild migratory waterbirds on Maliy Zhemchuzhniy Island in the Caspian Sea, Russia. The deaths were caused by highly pathogenic avian influenza A(H5N1) clade 2.3.4.4.b virus.

Preferential selection and contribution of non-structural protein 1 (NS1) to the efficient transmission of the panzootic avian influenza H5N8 2.3.4.4 clades A and B viruses in chickens and ducks [PDF]

, 2021
Highly pathogenic avian influenza virus H5N8 clade 2.3.4.4 caused outbreaks in poultry at an unprecedented global scale. The virus was spread by wild birds in Asia in two waves: clade 2.3.4.4A in 2014/2015 and clade 2.3.4.4B from 2016 up to today.

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Evaluation of the zoonotic potential of multiple subgroups of clade 2.3.4.4 influenza A (H5N8) virus

Virology, 2018
Clade 2.3.4.4 H5N8 highly pathogenic avian influenza viruses (HPAIVs) have spread worldwide. Phylogenetic analysis identified two genetic groups of the H5N8 HPAIVs in South Korea; group A evolved further into four subgroups. Here, we examined the zoonotic potential, both in vivo and in vitro, of genetically distinct subgroups of H5N8 HPAIVs isolated in

Novel Highly Pathogenic Avian Influenza A(H5N6) Virus in the Netherlands, December 2017

Emerging Infectious Diseases, 2018
A novel highly pathogenic avian influenza A(H5N6) virus affecting wild birds and commercial poultry was detected in the Netherlands in December 2017. Phylogenetic analysis demonstrated that the virus is a reassortant of H5N8 clade 2.3.4.4 viruses and not

Highly Pathogenic Avian Influenza A(H5N1) Virus Clade 2.3.4.4b in Wild Birds and Live Bird Markets, Egypt

Pathogens, 2022
Clade 2.3.4.4 H5Nx influenza viruses have further diversified into several subclades. Sub-clade 2.3.4.4b H5N1 viruses have been widely circulating in wild birds and detected in Europe, Africa, Asia, and North America since October 2020. In this study, we

Machine Learning‐Based Geospatial Risk Modeling of Global Avian Influenza Outbreaks

Transboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
The rapid spread of H5N1 avian influenza poses a global threat, highlighting the need for robust spatiotemporal risk assessment. In this study, we developed a global modeling framework integrating machine learning (ML) models and geospatial analysis to characterize H5N1 outbreak risk under varying environmental, ecological, and anthropogenic conditions.

Highly pathogenic H5 avian influenza in 2016 and early 2017 - observations and future perspectives [PDF]

, 2017
During 2016–2017 novel strains of highly pathogenic H5 avian influenza virus within the Goose/Guangdong/96 (Gs/GD/96)-lineage (mainly H5N8) caused multiple outbreaks of disease in poultry and wild birds across much of Europe, parts of Asia, the Middle ...

Highly Pathogenic Avian Influenza A(H5N8) Virus in Gray Seals, Baltic Sea

Emerging Infectious Diseases, 2019
We detected a highly pathogenic avian influenza A(H5N8) virus in lung samples of 2 gray seals (Halichoerus grypus) stranded on the Baltic coast of Poland in 2016 and 2017. This virus, clade 2.3.4.4 B, was closely related to avian H5N8 viruses circulating

First detection of highly pathogenic H5N6 avian influenza virus on the African continent

Emerging Microbes and Infections, 2020
Since 2013, highly pathogenic avian influenza (HPAI) subtype H5N6 (clade 2.3.4.4) has been reported in wild birds and poultry in Asia as well as in other parts of the globe. In Africa, information on the presence of this virus subtype is lacking.
