Oregon Dog Tests Positive for Canine Influenza Virus
The Oregon Health Authority received report of a dog that tested positive for H3N2 Canine Influenza Virus (CIV) in Grants Pass, Oregon. The dog a 7 year-old male Yorkie had traveled to Reno, Nevada with its owner where the dog was exposed to a known case of canine influenza. The owner and dog returned to Grants Pass on Feb 5th. The dog developed symptoms on Feb 9th. A nasal sample was collected and tested by IDEXX laboratories. The sample tested positive on Feb 12th. The dog has been under voluntary quarantine since February 5th and will remain quarantined for 30 days. At this point, the dog is recovering.
The Portland Veterinary Medical Association, the Oregon Veterinary Medical Association, and the State Public Health Veterinarian, Dr. Emilio DeBess, are recommending proactively vaccinating all at-risk dogs for CIV to protect and prevent an outbreak in our community.
Two Idaho Dogs Test Positive
The Idaho Veterinary Medical Association has received reports of dogs testing positive for Canine Influenza in Idaho. Both affected dogs, one in Boise and one in Rigby, are infected with Canine Influenza Virus (CIV) subtype H3N2. The IVMA has also heard reports of two dogs in Salt Lake City positive for CIV subtype H3N8. Canine Influenza is an emerging disease across the nation.
Canine Influenza has been affecting dogs in the Southern United States, Texas and the East Coast.
Canine Influenza has been affecting dogs in the Southern United States, Texas and the East Coast. There’s currently an outbreak in the San Francisco Bay Area. The Canine H3N2 Influenza Virus outbreak in Northern California continues to expand since the last update Friday, February 2nd 2018: The case load increased from 250 to 413 positive cases. There has been expansion within the primary area of the San Francisco South Bay, expansion in Reno, Nevada, and a further expansion to the South with the first positive case in Los Angeles. A local outbreak in Fresno, first detected January 23rd, has now increased to 53 (up from 31) H3N2 positive cases. New 2/23/18: A Redding veterinary clinic reports it is treating its first-ever case of canine influenza and is warning dog owners to take steps to prevent their pets from catching the virus.
Due to the close geographical relationship between Oregon, including the greater Portland area, and the San Francisco Bay Area and with many high-tech business links and frequent travel between these cities, the risk of introducing CIV (Canine Influenza Virus) could significantly increase in the Portland Area. In addition, the movement of rescue dogs coming to Portland from the Bay Area may also increase the chances of importing CIV to Oregon.
What Are the Signs of Exposure?
Dogs become ill three to seven days after exposure. Typical signs include a cough, decreased appetite, nasal and eye discharge, and fever. Most dogs will recover just like most humans will recover from the flu, but then a small population can actually die from the canine influenza.
Are All Dogs at Risk?
Dogs at increased risk of exposure include, but are not limited to:
- dogs with lifestyles that include dog parks, dog-daycare, dog shows, grooming, boarding, travel (car, air, etc.)
- rescue animals and dogs with pre-existing heart disease or lung disease
- potential senior (over 7 years of age) dogs, and
- brachycephalic (short nosed) breeds.
In general dogs should be vaccinated with a 2-dose series of a bivalent vaccine, 2-4 weeks apart. Full immunity does not occur until 7-10 days after the SECOND immunization in the initial series and is effective for 12 months. Boosters should then be given annually. Lapses on vaccine schedule past 18 months of the last vaccine without an annual booster should repeat the 2-dose series. There is no cross-protection from viral subtypes, or with other causes of kennel cough. At-risk patients should also be current on Bordetella. As with flu vaccination in people, total protection is not always possible, but clinical signs will be less severe and the duration of the illness may be shorter.
