Avian influenza overview September–November 2025

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Between 6 September and 28 November 2025, 2896 highly pathogenic avian influenza (HPAI) A(H5) virus detections were reported in domestic (442) and wild (2454) birds in 29 countries in Europe. The magnitude and geographical extent of these detections were unprecedented for this time of the year, particularly in wild birds.

A review of H5Nx avian influenza viruses

Therapeutic Advances in Vaccines and Immunotherapy, 2019
Highly pathogenic avian influenza viruses (HPAIVs), originating from the A/goose/Guangdong/1/1996 H5 subtype, naturally circulate in wild-bird populations, particularly waterfowl, and often spill over to infect domestic poultry.

The Next Disease X‐ H5N6 Avian Influenza's Evolving Threat to Human Health and Chances of Future Global Outbreak: A Narrative Review

Health Science Reports, Volume 8, Issue 11, November 2025.
ABSTRACT Background and Aims H5N6 avian influenza has been a concern that can initiate the next global pandemic (called Disease X). Most infections have been among those in Asia, especially China, since the 2014 first human case. With a fatality rate of 61%, the virus is very deadly, even though the total number of human cases is relatively low.

Genetic features of avian influenza (A/H5N8) clade 2.3.4.4b isolated from quail in Egypt

Virus Research
Several genotypes of the highly pathogenic avian influenza (HPAI) virus H5N8 subtype within clade 2.3.4.4b continue to circulate in different species of domestic birds across Egypt. It is believed that quail contribute to virus replication and adaptation

A Rapid Review Contrasting the Evidence on Avian Influenza A(H5Nx) Clades 2.3.4.4b and 2.3.2.1c in Humans

Zoonoses and Public Health, Volume 72, Issue 7, Page 553-586, November 2025.
ABSTRACT Avian influenza viruses (AIV) circulate in wild and domestic bird populations, posing an on‐going risk for zoonotic transmission and virus adaptation to mammals and humans. The A(H5Nx) clades 2.3.2.1c and 2.3.4.4b currently circulating have caused sporadic infections in humans.

Complex Reassortment Dynamics of H9N2 Avian Influenza Viruses in Xinjiang, China: Implications for Zoonotic Spillover

Influenza and Other Respiratory Viruses, Volume 19, Issue 10, October 2025.
ABSTRACT Background H9N2 avian influenza viruses (AIVs) donate their genes to other subtype AIVs, posing significant threats to poultry industries and public health due to their endemicity and zoonotic potential. This study investigates the molecular evolution, reassortment, and mutations of the H9N2 isolates from the live poultry markets (LPMs) in ...

Wildlife health risk analysis for conservation translocation: A scalable approach illustrated for wader population restoration

Conservation Science and Practice, Volume 7, Issue 9, September 2025.
We present a methodological framework for health risk analysis (disease risk analysis) for conservation translocation that enables the process to be scaled and adapted to the project context. We illustrate its application to two wader (shorebird) population restoration projects with differing translocation plans.

Efficacy of a Recombinant Turkey Herpesvirus AI (H5) Vaccine in Preventing Transmission of Heterologous Highly Pathogenic H5N8 Clade 2.3.4.4b Challenge Virus in Commercial Broilers and Layer Pullets

Journal of Immunology Research, 2018
Outbreaks caused by the highly pathogenic avian influenza virus (HPAIV) H5N8 subtype clade 2.3.4.4 were first reported in 2014 in South Korea then spread very rapidly in Asia, to Europe, and for the first time, to North America. Efficacy of a recombinant

Integrating Citizen Science and Remote Sensing Data to Identify Key Environmental Factors Influencing H5N1 Avian Influenza Virus Potential Spillover Risk in the Philippines

GeoHealth, Volume 9, Issue 8, August 2025.
Abstract Highly pathogenic avian influenza (HPAI) virus presents a serious threat to poultry and public health worldwide, with transmission dynamics shaped by avian migration patterns and environmental conditions. Recent outbreaks in the Philippines highlight the urgent need for effective control measures.
