How bird flu is spread
You can get bird flu by coming into close contact with birds that are infected with the bird flu virus.
You can also get it by touching the poo of an infected bird or an infected bird that has died.
Bird flu is found throughout the world, including the UK, but most infections in humans have happened in parts of Asia and North Africa.
