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 ...

Waterfowl Move Less in Heterogeneous and Human‐Populated Landscapes, With Implications for Spread of Avian Influenza Viruses

Ecology Letters, Volume 29, Issue 1, January 2026.
We show that non‐migratory waterfowl movement distances are shorter in areas of high land cover heterogeneity and human population density, and that these movement distances are related to the spread of highly pathogenic avian influenza. These results suggest that habitat management could contribute to the spread of these viruses.

Highly Pathogenic Avian Influenza A(H5N8) Clade 2.3.4.4b Viruses in Satellite-Tracked Wild Ducks, Ningxia, China, 2020

Emerging Infectious Diseases, 2022
During October 2020, we identified 13 highly pathogenic avian influenza A(H5N8) clade 2.3.4.4b viruses from wild ducks in Ningxia, China. These viruses were genetically related to H5N8 viruses circulating mainly in poultry in Europe during early 2020 ...

Duck STING Mediates Innate Immune Response Induced by H5N8 Subtype Avian Influenza Viruses

Acta Scientiae Veterinariae
Background: The H5N8 highly pathogenic avian influenza virus (HPAIV) poses a significant threat to global poultry and public health due to its high mortality rate and potential for cross-species transmission. As natural H5N8 hosts, Anatidae (e.g., ducks) drive transmission and evolution.
