The most significant impacts of influenza viruses on humans are those arising from the influenza A strains. The natural reservoir of influenza A strains is a diverse pool of viruses among aquatic wild bird populations – the avian influenza (AI) viruses.

19 lip 2024 · The best way to prevent H5N1 bird flu is to avoid sources of exposure whenever possible. Infected birds shed avian influenza A viruses in their saliva, mucous, and feces and other infected animals may shed avian influenza A viruses in respiratory secretions and other body fluids (e.g., cow milk).
The avian influenza virus can survive for up to 200 days in the body fluids of infected birds, four days in feces at animal body temperature, 35 days in feces at temperatures below 4 °C, and about five weeks in the environment of the infected poultry house [1, 64].
8 cze 2024 · Highly pathogenic avian influenza A (H5N1) viruses (clade 2.3.4.4b) continue to evolve and spread in many countries. 1 Since 2020, H5 influenza viruses have spread globally among wild birds, 1 causing outbreaks in poultry, 2 substantially impacting food safety and security. 3,4 From birds, spillover events to terrestrial and marine mammals have ...
EU legislation, particularly the Animal Health Law – Regulation (EU) 2016/429, sets out rules on the surveillance, control and eradication of avian influenza in Europe.
3 paź 2022 · Abstract. The 2021–2022 highly pathogenic avian influenza (HPAI) epidemic season is the largest HPAI epidemic so far observed in Europe, with a total of 2,467 outbreaks in poultry, 47.7 million birds culled in the affected establishments, 187 outbreaks in captive birds, and 3,573 HPAI virus detections in wild birds with an unprecedent ...
Avian influenza is a highly contagious viral disease which occurs primarily in poultry and wild water birds. Wild birds are natural hosts and reservoirs for all types of avian influenza viruses, so play a major role in the evolution, maintenance and spread of these viruses.
