What is Avian Influenza (AI)?

It's a disease caused by a virus that occurs naturally in wild birds. The majority of avian influenza viruses don't cause problems for birds but some strains are deadly for chickens. Sometimes, the virus can be transmitted to humans who have close contact with infected birds.

What are the symptoms of this disease in birds?

Early signs of disease include apathy, a decline in egg production, eye infections, swollen combs, coughing and diarrhoea. If the infection is in chickens, most of the flock will die within a few days. Lab tests are required to confirm the disease.

How is the disease transmitted to domestic birds?

Domestic fowl catch the disease by contact with wild birds or their droppings. Once in a barn, the virus spreads very rapidly throughout the flock. To prevent further spread from an infected barn, workers should dispose of, or decontaminate, all clothing, shoes, vehicles, and equipment.

Is avian influenza communicable to humans?

Some avian influenza viruses, like the highly pathogenic H5N1 found in Asia, can cause disease in humans. This is rare and requires close contact with infected birds or a contaminated environment. People who will come in contact with infected fowl should wear protective clothing such as a mask, glasses, gloves and boots.

Are Canadians as exposed to this sickness as people in Asia?

The risk of contracting avian influenza in Canada isn't the same as in Asia or in Africa where people and fowl have daily contact in public markets and throughout the countryside. Canadian farmers have better on-farm biosecurity to protect their flocks and easy access to veterinary services.

Farmers should limit contacts between wild birds and their flocks. We recommend putting wire netting over openings of their barns. They can prevent introduction of the virus in their barn by disinfecting boots and other equipment before entering. Farmer should wear one set of coveralls per barn, to prevent transfer of virus to another barn.

What is the CFIA's role in fighting against avian influenza and stopping its infecting the breeds of Canada?

The Agency gives advice on prevention to farmers, but its main role is fighting the disease whenever it is suspected on a farm. This requires quarantines, depopulation, and disinfection of the barns and surrounding area. The Agency also decides on border controls to prevent travellers and importers from bringing to Canada infected birds or bird products.

What can travellers do to avoid introducing the disease into the country?

Several days before entering Canada, travellers should avoid public markets and other areas where birds gather. This will reduce the likelihood that their clothes or shoes could be contaminated and harbour the virus. Travellers must also declare all birds, poultry meat or poultry products, including feathers and duvets that they may be bringing to Canada. Particularly if the visitor has been in a country with an avian influenza outbreak.

Is it possible for other animals to contract avian influenza?

Avian influenza normally affects birds.   The most susceptible are domesticated birds like chickens, turkeys, quail, and guinea-fowl, but wild birds can also be affected.  However, some mammals, can occasionally contract the disease like pigs, cats, and ferrets.
