Avian Influenza FAQs - 17 Found
The role of wild birds in the transmission of the highly pathogenic (HPAI) strain of the H5N1 avian influenza virus currently remains unclear. The primary mode of H5N1 spread in Asia appears to be in the poultry trade, but migratory wild birds are recognized as a secondary source of spread in some locations. In 2005, over 6,000 wild birds died during an outbreak of H5N1 in north-central China at Qinghai Lake – an area devoid of domestic poultry. Avian influenza that spread beyond Asia and into Europe and Africa was later found to have genetically originated in the Qinghai Lake area.
No HPAI H5N1 has been detected in North America, despite extensive efforts to test migratory birds to provide early warnings should birds with the virus arrive in the country.
