Earlier this week, H3N2 canine influenza was identified in two dogs in Essex County. The Windsor-Essex County Health Unit (WECHU) has now confirmed that 5 dogs that were in close contact with the affected dogs have tested positive for canine influenza. Affected and exposed dogs are being confined by their owners to help prevent further spread.
Canine influenza virus is of concern because it is highly transmissible between dogs, particularly in areas (such as Canada) where dogs do not have natural immunity from previous infection and where canine influenza vaccination is rare.
A few important points should be noted:
- Most dogs that develop influenza do not get seriously ill. Respiratory disease that is indistinguishable from other infectious respiratory diseases (canine infectious respiratory disease complex, also known as ‘kennel cough’) usually occurs, although serious (including fatal) infections and/or complications can develop.
- Infected dogs can shed influenza virus for a short time prior to the onset of disease. So, dogs that appear to be healthy are still a potential source of infection.
- Canine influenza vaccines can reduce the risk of disease and are available from veterinarians in Canada.
- Cats can be infected but this appears to be rare.
Canine H3N2 influenza virus is different than the human H3N2 influenza virus that is a common seasonal flu virus in people. There is no known human risk from H3N2 canine influenza virus; however, the risk of reassortment (or mixing together) between the canine H3N2 virus and human seasonal influenza viruses is a potential concern. As influenza in animals is a reportable disease, the Windsor-Essex County Health Unit, the Ontario Ministry of Health and Long-Term Care (MOHLTC), and Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) are involved in the investigation, along with the University of Guelph.
Because canine influenza virus (as well as other infectious causes of respiratory disease) can be highly contagious, care must be taken with sick dogs. Dog owners in Windsor and Essex County should be vigilant and watch for signs of respiratory disease in their dogs, particularly dogs that frequently have contact with other dogs. Dogs with signs of respiratory disease (e.g. cough, decreased appetite, nasal and eye discharge, and fever) should be kept away from others dogs for at least 2 weeks. If a dog with potentially infectious respiratory disease is taken to a veterinarian, the veterinary clinic should be informed in advance so that they can take appropriate precautions, such as admitting the dog directly to an examination or isolation room and using isolation precautions.
More information will be provided as it becomes available.
