Why has there been surveillance for certain types of influenzas in some animals for many years?
Owing to their impact on animal health and more recently the impact of H5N1 Highly Pathogenic Avian Influenza (HPAI) on human health, there has been extensive surveillance for influenza viruses in domestic and wild birds, particularly of avian influenza viruses of subtypes H5 and H7, but also other subtypes. HPAI viruses and low pathogenic avian influenza viruses (LPAI) of subtypes H5 and H7 in domestic poultry, and influenza in horses are OIE listed diseases, and OIE Members must have surveillance in place and report occurrences of these diseases.
