Avian influenza (also known as ‘bird flu’) is a virus that typically infects birds. Strains of avian influenzas may be low pathogenicity (does not usually cause serious disease) or high pathogenicity (capable of causing serious disease).
Since 2021, a new strain of highly pathogenic avian influenza has been circulating around the world and causing large numbers of deaths in a variety of bird species, including domestic chickens. This strain has not been detected in Australia, but there is concern that it may be introduced. If introduced to Australia, this viral strain would have serious impacts on Australia’s agricultural industry and our native birds.
Affected birds may:
- Be found dead, especially in groups.
- Show abnormal behaviour including lack of coordination, walking or swimming in circles, or be unable to fly.
- Have diarrhoea (runny poo).
- Have mucus around the eyes or beak.
- Cough, sneeze or have difficulty breathing.
Any findings that are suspicious for avian influenza should be reported immediately to the Emergency Animal Disease Hotline 1800 675 888.
People can be infected with some strains of Avian Influenza, although this is uncommon. Avoid contact with birds that may be infected. If you do come into contact, wash your hands well with soapy water or use hand-sanitiser.
