Cases of avian influenza declining in Europe

Published 2024년 7월 29일

Tridge summary

Europe has seen a significant decline in highly pathogenic avian influenza (HPAI) cases in poultry and wild birds, reaching the lowest levels since 2019/2020, according to a report by EFSA, ECDC, and EURL. This improvement is attributed to factors like flock immunity and reduced viral contamination. However, 15 HPAI outbreaks were still reported in Hungary and Bulgaria. Globally, HPAI remains prevalent in North America and Asia, with new detections in mammals in the US and Norway. The A(H5N1) virus genotype B3.13 has spread across over 130 dairy farms in 12 US states, affecting various species and leading to sporadic zoonotic cases. Enhanced surveillance is recommended for the upcoming influenza season.

Europe has recorded the lowest number of highly pathogenic avian influenza cases in poultry and wild birds since 2019/2020. These are the main findings of the latest report on avian influenza by the European Food Safety Authority (EFSA), the European Centre for Disease Prevention and Control (ECDC), and the EU reference laboratory (EURL), based on reported data between 16 March and 14 June 2024. 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. Between 16 March and 14 June 2024, 15 HPAI outbreaks in poultry were reported from 2 countries in Europe: 8 A(H5N1) from Hungary ...
