Avian influenza is a viral disease of birds that is found globally. Virus strains are described as low pathogenicity (LPAI) or high pathogenicity (HPAI). High pathogenicity H5N1 avian influenza (H5 bird flu) is currently affecting all parts of the world except Australia and Oceania.
While we have responded to HPAI H7 detections in NSW in the past, there has never been a detection of H5 bird flu in Australia. Despite this, we must remain aware of the threat of H5 bird flu arriving in Australia.
H5 bird flu differs from other avian influenza strains and has caused mass mortalities in poultry and many wild birds overseas, as well as some mammals, particularly marine mammals.
H5 bird flu:
- spreads more easily than other bird flu strains
- can kill large numbers of wild birds
- has no effective treatment
- usually leads to poor outcomes for infected birds and mammals
We are preparing for a possible outbreak of H5 bird flu in Australia and are working to enhance preparedness and response capabilities. This includes considering the potential impacts to animals, people and our ecosystems.
