H5N1 bird flu reaches Australia, completing global spread to every continent

The Age—Australia confirmed its first and then second cases of H5N1 bird flu, making it the final continent to report the virus and marking a significant milestone in the global spread of the pathogen. Western Australian poultry farms including Inghams, one of Australia's largest chicken producers, were locked down after the second detection in a migratory seabird. Officials are tracking how the virus arrived and where it may spread next, with experts noting migratory birds are the most likely vector.
