Europe has seen a significant decline in highly pathogenic avian influenza (HPAI) cases in poultry and wild birds, reaching the lowest numbers since 2019/2020, as reported by EFSA, ECDC, and EURL for the period from 16 March to 14 June 2024. This improvement is attributed to factors like flock immunity and reduced viral contamination. However, the situation remains critical outside Europe, with notable outbreaks in North America and Asia, and new detections in mammals in the US and Norway. The A(H5N1) virus genotype B3.13 has spread among various mammal species in America, affecting over 130 dairy farms in 12 US states. Sporadic human cases of various avian influenza strains have also been reported globally, prompting experts to recommend enhanced surveillance for the upcoming influenza season.

The report further noted that the risk to the general public remains low. The improvement in the situation regarding the number of cases of avian influenza in Europe could be linked to several factors, which could include flock immunity acquired by certain wild bird species, depletion of some wild bird populations, reduced viral contamination of the environment, changing composition of circulating HPAI virus genotypes, and decreased detection of dead wild birds. Domestic birds Between 16 March and 14 June 2024, 15 HPAI outbreaks in poultry were reported from 2 countries in Europe: 8 ...
