The latest information on highly pathogenic avian influenza (HPAI) is not good. The February 2025 bulletin, compiling observations from the network of veterinarians in the World Organization for Animal Health (WHO), reveals a worsening of the spread of different virus strains (H5-N1, H5-N3, H5-N8, etc.) throughout the world, particularly in the northern hemisphere. In February alone (the virus develops in winter with lower temperatures like human flu), 121 epidemics were reported in poultry farms and 166 in wild birds and mammals. 11.4 million birds died in that month alone.

Avian influenza is affecting increasingly large populations of wild and domestic birds and is spreading to mammals. The World Organisation for Animal Health (WHO) now considers highly pathogenic avian influenza to be endemic in the Northern Hemisphere.
In 2023, the avian flu virus was identified in several black-headed gulls in Toulouse.
