Avian influenza, or bird flu, is an infectious disease affecting poultry and wild birds in Australia, and across the world. Avian influenza has many different viral strains, some of which can infect humans and other animals.
In particular, the H5N1 (clade 2.3.4.4b) strain is highly contagious and causes serious disease. This strain of H5 bird flu has spread rapidly around the world and has sadly caused the deaths of millions of birds and mammals, including seals, sea lions, and penguins.
Unfortunately, H5 bird flu has now been detected in migratory seabirds in a number of Australian states. Australia was previously the only continent in the world to be free of this strain.
This is highly concerning for our wildlife, with one in six Australian birds already facing the threat of extinction, and the animals in our agricultural industries, with poultry highly susceptible to the virus and dairy cattle infections reported overseas.
