Australia Detects H5N1 Bird Flu in Wild Seabird—First Confirmed Case

Australia has confirmed its first H5N1 detection in a wild migratory seabird near Esperance, Western Australia. The strain—clade 2.3.4.4b—traveled via Southern Ocean routes, the same pathway documented in South America. Authorities now monitor for spread to wild populations and commercial poultry, where spillover would trigger immediate trade restrictions worldwide.
