In the last quarter of 2024, specifically between September 21 and December 6, a total of 657 highly pathogenic avian influenza (HPAI) A(H5N1) and A(H5N5) virus detections were reported in Europe. These detections occurred in both domestic (341 cases) and wild birds (316 cases) across 27 countries. The outbreaks in domestic birds were notably clustered in areas with high poultry density and were characterized by secondary farm-to-farm spread. Additionally, there were 67 reported outbreaks of HPAI in captive birds from 14 countries, with Moldova reporting the highest number (29 outbreaks), followed by Czechia (12), and several other countries with fewer cases. A recent EFSA report indicates a significant impact on waterfowl, particularly mute swans, and an increase in virus detections among gulls and crows. However, there were no new HPAI detections reported in mammals in Europe during this period. Overall, the situation reflects ongoing challenges in managing avian influenza outbreaks, particularly in poultry and captive bird populations.
