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 Rationally Designed H5 Hemagglutinin Subunit Vaccine Provides Broad-Spectrum Protection against Various H5Nx Highly Pathogenic Avian Influenza Viruses in Chickens

Vaccines
The evolution of the H5 highly pathogenic avian influenza (HPAI) viruses has led to the emergence of distinct groups with genetically similar clusters of hemagglutinin (HA) sequences.

Highly Pathogenic Avian Influenza (H5N1) in Humans after the emergence of clade 2.3.4.4b in 2020.

Global Biosecurity, 2023
The highly pathogenic avian influenza virus A (HPAI) H5N1 was first identified in a farmed goose in 1996 from China. High pathogenic avian influenza viruses cause severe disease in poultry and represent a smaller proportion of avian influenzas.

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.

A Systematic Review of New, Enhanced Surveillance Systems and Methodologies for Zoonotic Influenza Viruses in Animals and Human–Animal Interface

Influenza and Other Respiratory Viruses, Volume 19, Issue 11, November 2025.
ABSTRACT In 2009, the World Health Organization (WHO) developed a public health research agenda for influenza to guide researchers and outline directions and priority areas for research on influenza aiming at reducing the burden of seasonal epidemic influenza and the risk and impact of pandemic influenza. The agenda was updated in 2017, but since then,
