Australia Confirms First Local Bird Flu Spread in Wildlife
29 Jul
Summary
- First local transmission of H5 bird flu confirmed in Australian wildlife.
- Poultry and agricultural industries remain unaffected by the outbreak.
- Risk to human health is considered low by authorities.
Australian authorities have confirmed the first detection of local H5 bird flu transmission within the country's wildlife populations. The virus has been identified in wild seabirds, with 27 confirmed cases reported across Western Australia, South Australia, New South Wales, and Queensland.
The Consultative Committee on Emergency Animal Diseases, following testing and sequencing by the CSIRO lab, concluded that local transmission has occurred among greater crested terns in South Australia. Officials anticipate further detections in Australian wildlife but stress that poultry and agricultural sectors are unaffected.
The risk to human health remains low. Chief Veterinary Officer Beth Cookson noted that increased local transmission in coastal-dwelling birds was expected and could lead to wider spread among susceptible wildlife.
Authorities are prioritizing surveillance to track the virus's circulation and mitigate impacts. Initial cases were linked to petrels believed to have arrived from Antarctic and Sub-Antarctic regions. Monitoring for onward spread to other species continues.
