About AIH
Bird flu (avian influenza) is caused by specific influenza A viruses that usually infect birds. These viruses are different to those that cause seasonal flu in people.
Bird flu rarely spreads to people. When it does, it most often causes a respiratory infection.
The current risk of bird flu to people in Australia is considered low.
Bird flu in humans is an acute respiratory infection caused by influenza A viruses that usually infect birds.
Like all influenza A viruses, bird flu viruses are classified into subtypes by 2 surface proteins:
Virus subtypes – for example, H5N1 and H7N9 – are formed through different combinations of these surface proteins.
Each subtype differs in its ability to spread and cause disease. Five bird flu subtypes (H5, H6, H7, H9 and H10) are known to infect people.
Most reported infections in people are caused by:
Bird flu viruses are further classified into genetic subgroups called clades (clades and subclades are based on the haemagglutinin component) and genotypes (the genotype takes account of all the genetic segments of the virus), which help track:
Bird flu viruses are also classified by severity of disease (pathogenicity) in poultry, as either:
HPAI and LPAI viruses can cause severe disease in people.
Water birds – such as waterfowl, gulls and shorebirds – are the main natural reservoir for bird flu viruses.
