A highly pathogenic strain of avian influenza, known as H5N1, has been confirmed in Victoria, Australia, marking the first detection of this strain in the state. The virus was identified in a greater crested tern found dead at Robe Marina, a non-migratory seabird species. This detection follows previous confirmations of H5N1 in wild seabirds in Western Australia, South Australia, Queensland, and New South Wales.
H5N1 is a highly contagious virus that can cause severe illness and death in birds. While human infections are rare, the virus has been known to infect humans in other parts of the world. The Australian Centre for Disease Control has assessed the risk to human health in Australia as low, emphasizing that bird flu rarely spreads to people and that transmission requires close contact with infected birds or contaminated environments.
Authorities are urging the public to remain vigilant and report any sick or dead wild birds and other wildlife. Residents are advised not to touch dead wildlife and to report such findings to the Emergency Animal Disease Hotline.
The detection of H5N1 in Victoria underscores the importance of biosecurity measures to prevent the spread of avian influenza. While there are currently no confirmed detections in poultry in Australia and no signs of mass wildlife deaths, the situation remains dynamic. Ongoing surveillance and public cooperation are essential to monitor and manage the potential impact of this virus on both wildlife and human health.
