Guidance on how to spot avian influenza (bird flu), what to do if you suspect it and measures to prevent it.

Avian influenza mainly affects birds. It can also affect humans and other mammals.

How to spot avian influenza

There are 2 types of avian influenza.

Highly pathogenic avian influenza (HPAI) is the more serious type. It is often fatal in birds. The main clinical signs of HPAI in birds are:

  • swollen head
  • blue discoloration of neck and throat
  • loss of appetite
  • respiratory distress such as gaping beak, coughing, sneezing, gurgling, rattling
  • diarrhea
  • fewer eggs laid
  • increased mortality

Clinical signs can vary between species of bird and some species may show minimal clinical signs (ducks and geese).

Low pathogenic avian influenza (LPAI) is usually less serious. It can cause mild breathing problems, but affected birds will not always show clear signs of infection.

The severity of LPAI depends on the type of bird and whether it has any other illnesses.

If you suspect any strain of avian flu you must tell your nearest Animal and Plant and Health Agency (APHA) office immediately. Failure to do so is an offence
