Avian Influenza and Poultry (Health Canada).The Public Health Agency Canada also provides advice on precautions to be taken when handling wild birds. This includes, face masks, goggles, gloves and boots. Transmission to humans has occurred when people have had close contact with infected birds or heavily contaminated environments.ĭue to the potential for human infection, it is recommended that people working with poultry suspected of being infected with avian influenza, or in contact with such poultry, wear protective clothing. Avian influenza in humansĪvian influenza viruses, such as the highly pathogenic H5N1 virus present in Asia, can, on rare occasions, cause disease in humans. For example, the H5N1 strain that has been reported in various parts of Europe is low pathogenic and is distinctly different from the Asian strain, which is highly pathogenic. Such strains can have very different characteristics and structure. These 2 H-types have been known to cause serious disease or mortality in domestic poultry, yet low pathogenic H5 and H7 viruses are quite common in wild waterfowl.ĭifferent strains of the same type of virus can exist, particularly in different parts of the world.

The H5 and H7 subtypes of the virus are of particular concern, given the ability of these 2 H-types to mutate from low pathogenic to highly pathogenic after they infect domestic birds. There are 16 H types and 9 N types which create a total 144 possible combinations. Different strains of avian influenzaĪvian influenza viruses are divided by subtypes based on 2 proteins found in the viruses: hemagglutinin, or 'H' protein, and neuraminidase, or 'N' protein. However, highly pathogenic viruses can cause severe illness and death in birds. These typically cause little or no signs of illness in infected birds. Most avian influenza viruses are low pathogenic. highly pathogenic avian influenza (HPAI).This virus can affect several species of food-producing birds (chickens, turkeys, quails, guinea fowl, etc.), as well as pet and wild birds.Īvian influenza viruses can be broadly classified into 2 types, based on the severity of the illness caused in birds: What travellers can do to help protect Canadian livestock from an outbreak of avian influenzaĪvian influenza (AI), often called 'bird flu,' is caused by the Type 'A' influenza virus.How the CFIA responds to an outbreak of avian influenza in Canada.
