Avian influenza overview June-August 2026

Between 5 June and 28 August 2026, 110 highly pathogenic avian influenza (HPAI) A(H5N1) virus detections were reported in domestic (7) and wild (103) birds in 12 countries in Europe. The number of detections remained at a seasonal low throughout the summer, continuing the decline observed since spring. In contrast to previous years, fewer colony-breeding seabirds were affected, and the geographical range of detections was more limited. Further sporadic detections of HPAI A(H5) virus were reported in wild terrestrial carnivores and pinnipeds.
