Avian Influenza (Bird Flu)
HPAI Bird Flu - what you need to know
- Although NZ has never had a case of high pathogenicity avian influenza (HPAI) bird flu MPI Biosecurity NZ anticipates that it is most likely that it is only a matter of time before it reaches our shores most probably via migratory birds.
- The focus is on early detection so that we can react quickly should HPAI bird flu arrive in NZ.
- HPAI bird flu has spread to all areas except Oceania, infecting 500+ bird species and 60 mammal species.
- Human cases have been rare - generally a result of close contact with an infected bird or animal.
- MPI is working closely with wildlife hospitals, poultry industry groups, vets and rehabilitation centres on monitoring and awareness.
- Field surveillance programmes will be conducted over summer looking for exotic diseases in wild bird populations.
- Good biosecurity is an essential first line of defence – particularly on poultry farms and other facilities with domestic or wild birds.
- Implementing rigorous biosecurity now could protect individual farms and backyard poultry from infection.
What to watch out for
HPAI clinical signs in wild birds
- Several dead birds in a group.
- Neurological signs – drowsiness, lack of co-ordination, and an inability to fly.
- Disease may have a slower onset and progression than poultry.
- Younger birds and more virulent strains show more severe disease.
What to do if you suspect HPAI Bird Flu
- Report three or more sick or dead wild birds to Biosecurity New Zealand’s Exotic Pest and Disease hotline on 0800 80 99 66 .
- Sick or dead birds should not be handled.
