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 ...

A Monoclonal Antibody ELISA–Based Assay for Measuring the Potency of Candidate H5 Clade 2.3.4.4b Pandemic Influenza Vaccines

Influenza and Other Respiratory Viruses, Volume 20, Issue 3, March 2026.
ABSTRACT Background The single radial immunodiffusion (SRID) assay is used to determine the potency of inactivated influenza vaccines. Nevertheless, development of alternative influenza vaccine potency assays with greater sensitivity and less reliance on large quantities of reference reagents is needed.

Isolation and characterization of H5Nx highly pathogenic avian influenza viruses of clade 2.3.4.4 in Russia

Virology, 2018
In 2016-2017, several subtypes of the highly pathogenic avian influenza (HPAI) virus were isolated on the territory of Russia. In the autumn of 2016, during the avian influenza virus surveillance in the territory of the Kamchatka region of Russia the HPAI A(H5N5) influenza virus was isolated.

Neutralizing and protective murine monoclonal antibodies to the hemagglutinin of influenza H5 clades 2.3.2.1 and 2.3.4.4

Influenza and Other Respiratory Viruses, 2023
AbstractBackgroundHighly pathogenic avian H5 influenza viruses have spread and diversified genetically and antigenically into multiple clades and subclades. Most isolates of currently circulating H5 viruses are in clade 2.3.2.1 or 2.3.4.4.MethodsPanels of murine monoclonal antibodies (mAbs) were generated to the influenza hemagglutinin (HA) of H5 ...

Transmission Dynamics of Highly Pathogenic Avian Influenza Virus A(H5Nx) Clade 2.3.4.4, North America, 2014-2015. [PDF]

Emerg Infect Dis, 2018
Eurasia highly pathogenic avian influenza virus (HPAIV) H5 clade 2.3.4.4 emerged in North America at the end of 2014 and caused outbreaks affecting >50 million poultry in the United States before eradication in June 2015. We investigated the underlying ecologic and epidemiologic processes associated with this viral spread by performing a comparative ...

Avian influenza overview December 2025–February 2026

EFSA Journal, Volume 24, Issue 3, March 2026.
Abstract Between 29 November 2025 and 27 February 2026, 2514 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (406) and wild (2108) birds in 32 countries in Europe. Albeit still at high levels after the peak was reached at the beginning of the current reporting period, the weekly number of detections has since ...
