Construction and Immune Strategy Optimization of a Vaccine Strain for Influenza A (H5N8) Subtype [PDF]

Viruses
Multiple subtypes of avian influenza virus (AIV), including H5N1, H5N6, and H5N8 viruses, are currently co-circulating in wild birds and poultry and causing sporadic human infections. Vaccine development is essential for pandemic preparedness.

Highly pathogenic avian influenza virus of the A/H5N8 subtype, clade 2.3.4.4b, caused outbreaks in Kazakhstan in 2020 [PDF]

PeerJ, 2022
Background Large poultry die-offs happened in Kazakhstan during autumn of 2020. The birds’ disease appeared to be avian influenza. Northern Kazakhstan was hit first and then the disease propagated across the country affecting eleven provinces. This study

Pathogenicity of highly pathogenic avian influenza H5N8 subtype for herring gulls (Larus argentatus): impact of homo- and heterosubtypic immunity on the outcome of infection [PDF]

Veterinary Research, 2022
To improve understanding of the pathobiology of highly pathogenic avian influenza virus (HPAIV) infections in wild birds, pathogenicity and transmissibility of HPAIV H5N8 subtype clade 2.3.4.4b was evaluated in ~ 8-week-old herring gulls (Larus ...

Novel Genotype of HA Clade 2.3.4.4b H5N8 Subtype High Pathogenicity Avian Influenza Virus Emerged at a Wintering Site of Migratory Birds in Japan, 2021/22 Winter [PDF]

Pathogens
Surveillance of avian influenza virus (AIV) was conducted in the 2021–2022 winter season at a wintering site of migratory Anatidae in Japan. An H5N8 subtype high pathogenicity AIV (HPAIV) with a unique gene constellation and four low pathogenicity AIVs ...

Serological Surveillance of Avian Influenza Virus Exposure Using Paired Sera Among Occupational Contacts in Taiwan, January-September 2025. [PDF]

Influenza Other Respir Viruses
ABSTRACT In 2025, Taiwan implemented paired sera surveillance among occupational contacts of avian influenza viruses (AIVs). Of 122 contacts analyzed, 117 (95.9%) remained asymptomatic with high personal protective equipment compliance (91.8%). No seroconversion was detected against AIV A(H5N2) clade 2.3.4.4b. These findings suggest a low risk of human

Nomenclature Updates to the Hemagglutinin Gene Clade Designations Resulting From the Continued Evolution of High Pathogenicity Avian Influenza A(H5) Virus Clades 2.3.2.1c and 2.3.4.4 [PDF]

Influenza Other Respir Viruses
ABSTRACT Background and Methods The evolutionary divergence of the A(H5) hemagglutinin (HA) gene of high pathogenicity avian influenza (HPAI) viruses (A/goose/Guangdong/96 lineage) was analyzed by phylogenetic and average pairwise distance methods to identify clades that merit nomenclature updates.

Emergence of Novel Highly Pathogenic Avian Influenza Virus A(H5N1) Clade 2.3.4.4b in Commercial Poultry, Bangladesh. [PDF]

Influenza Other Respir Viruses
ABSTRACT Background The high‐pathogenicity avian influenza (HPAI) viruses represent a main threat to animal and human health, poultry productivity, and ecosystems. The newly evolved A(H5N1) clade 2.3.4.4b has become a worldwide concern for its expanding multihost ecology, including poultry and a wide range of mammalian species.
