An insight into disease lingo
With the detection of H5 avian influenza detected in wild migratory birds in some states of Australia, there have been many terms used to describe the disease.
Often you may see different terms used in the news media, government information and industry updates.
So, what is the right way to describe it?
The preference is to use Highly Pathogenic Avian Influenza (HPAI) or avian influenza over bird flu . This is largely about accuracy, consistency, and risk communication.
Here are the key reasons:
- Bird flu is a media term, not the technical term. It is widely understood by the public, but it lacks precision. “Avian influenza” is the internationally accepted scientific and regulatory term used by organisations such as World Organisation for Animal Health, Food and Agriculture Organization of the United Nations and World Health Organization.
- Not all avian influenza viruses are the same. “Avian influenza” covers many influenza A viruses in birds. Some are:Saying “bird flu” does not distinguish between these very different disease types.
- Low Pathogenic Avian Influenza (LPAI) – often causing mild or no disease.
- Highly Pathogenic Avian Influenza (HPAI) – capable of causing severe disease and high mortality in poultry.
- HPAI identifies the level of disease risk. When discussing outbreaks affecting commercial poultry, using “HPAI” immediately communicates that it is the highly pathogenic form requiring strict biosecurity, movement controls, and eradication measures.
- It avoids unnecessary confusion. The term “bird flu” can imply that all birds have the disease or that all wild birds are equally responsible for spreading it. In reality, only some birds are infected, and disease dynamics vary by species and virus strain.
- It aligns with government terminology. Governments, industry organisations, and emergency animal disease response documents consistently use “avian influenza” and “HPAI,” ensuring everyone is using the same language during an outbreak.
When is “bird flu” appropriate?
“Bird flu” can still be useful in communications aimed at the general public because it is a familiar term. A common approach is to introduce both terms together:
Highly Pathogenic Avian Influenza (HPAI), commonly known as bird flu, has been detected…
After that first reference, continue using HPAI or avian influenza throughout the document.
For industry communications, board papers, government correspondence, and media statements from Egg Farmers of Australia should:
- Use Highly Pathogenic Avian Influenza (HPAI) when referring to the current poultry disease.
- Use avian influenza when discussing the disease more broadly.
- Reserve bird flu only as a plain-English explanation for public audiences or media, ideally only on first mention. This approach is technically accurate while remaining accessible.
