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.

Genetic characterization of an H5N6 avian influenza virus with multiple origins from a chicken in southern China, October 2019

BMC Veterinary Research, 2021
Background Highly pathogenic avian influenza viruses (HPAIVs) of H5 subtype pose a great threat to the poultry industry and human health. In recent years, H5N6 subtype has rapidly replaced H5N1 as the most predominate HPAIV subtype circulating in ...

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.

Respiratory disease due to mixed viral infections in poultry flocks in Egypt between 2017 and 2018: Upsurge of highly pathogenic avian influenza virus subtype H5N8 since 2018.

Transboundary and Emerging Diseases, 2019
For several years, poultry production in Egypt has been suffering from co-circulation of multiple respiratory viruses including highly pathogenic avian influenza virus (HPAIV) H5N1 (clade 2.2.1.2) and low pathogenic H9N2 (clade G1-B).

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.

Spread of Highly Pathogenic Avian Influenza (HPAI) H5N5 Viruses in Europe in 2016–2017 Appears Related to the Timing of Reassortment Events

Viruses, 2019
During the epizootic of highly pathogenic avian influenza (HPAI) H5N8 virus in Europe in 2016−2017, HPAI viruses of subtype H5N5 were also isolated. However, the detection of H5N5 viruses was limited compared to H5N8.

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.
