Bird flu

Also called Avian influenza or H5N1

Bird flu is an infection caused by flu viruses that mainly affect wild birds and poultry. People catch it only very rarely, usually through close contact with infected birds or their droppings. It does not spread easily from person to person, but some strains can cause serious illness.

What it is

Most at risk are people who handle poultry or wild birds. Properly cooked poultry and eggs are safe to eat.

Antiviral medicines can be given to people who are ill or who have been exposed. Health authorities track outbreaks closely.

Common signs

  • High temperature and aching muscles
  • Cough and breathlessness
  • Sore red eyes (conjunctivitis)
  • Diarrhoea or being sick

How it is usually diagnosed

  • A nose and throat swab tested in a lab
  • Questions about contact with birds and travel

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Swab results
  • Notes on the date and type of bird contact
  • Any treatment or preventive antivirals given

Questions to ask your doctor

  • Do I need antiviral medicine after this exposure?
  • Should the people I live with be checked?
  • Which symptoms should make me seek help?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Severe breathlessness, chest pain or confusion after contact with birds: call 112 and mention the bird contact
