Comparative pathogenicity and environmental transmission of recent highly pathogenic avian influenza H5 viruses

Emerging Microbes and Infections, 2021
Strategies to control spread of highly pathogenic avian influenza (HPAI) viruses by wild birds appear limited, hence timely characterization of novel viruses is important to mitigate the risk for the poultry sector and human health.

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 ...

Article The Genotype Diversity within the H5N8 Influenza A Subtype [PDF]

, 2018
The H5N8 influenza subtype has been involved in the global spread of the Guangdong variant of the H5 hemagglutinin. The sequence data from all of the complete genomes from the H5N8 subtype was used to analyse the genotype diversity. Clustering analysis was used to assign lineages to each of the segments where different lineages were present.

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.

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

From sporadic to global: The changing face of H5N8 [PDF]

, 2015
The H5N8 influenza subtype is a relatively new highly pathogenic avian influenza. Until the recent Korean outbreak of H5N8 the viral subtype had only been detected sporadically. This paper looks at the multiple reassortment events between H5 hemagglutinin and N8 neuraminidase segments that explain the breaks in the history of the H5N8 subtype ...

Neuroinvasive influenza virus A(H5N8) in fattening ducks, Hungary, 2015

Infection, Genetics and Evolution, 2016
Highly pathogenic avian influenza (HPAI) A virus H5N8 was detected in far east Asian countries during 2014 and emerged in late 2014 in European countries. Hungary reported a HPAI A(H5N8) outbreak during late winter of 2015 at a Pekin duck fattening facility. Epidemiologic monitoring was extended to holdings in neighboring areas and nearby habitats used

Prevalence of the H5N8 influenza virus in birds: Systematic review with meta-analysis

Travel Medicine and Infectious Disease, 2023
Avian influenza viruses are members of the Orthomyxoviridae family, considered highly pathogenic (HPAI). They result from genetic variations from their low virulence predecessors. HPAI is a global problem. Large outbreaks of HAPI have significant health and economic impacts.The objective of this study was to assess the prevalence of the H5N8 Influenza ...
