BIVALENT CANINE INFLUENZA VIRUS VACCINE AVAILABLE AT GRAYVIK ANIMAL CARE CENTER      8/23/17

 

WHAT IS THE CANINE INFLUENZA VIRUS?

The Canine Influenza Virus (CIV) is a highly contagious respiratory tract infection largely caused by two subtypes of the Influenza A virus: H3N8 and H3N2. 

The United States is the only country where both viruses have been found circulating in our dog population. The H3N8 virus was first found in racing Greyhounds between 2003-2005 and is currently found in 39 states including Florida. The H3N2 virus originated in China and South Korea. It was first identified in the US in 2015. It has currently been found in 30 states including Florida.

 

WHAT ARE THE CLINICAL SIGNS?

CIV causes respiratory symptoms similar to those experienced by humans with the flu.  Most dogs will show mild clinical signs which are typically self-limiting. The most common are transient fever, coughing, sneezing and discharge from the eyes and nose. In a small number of dogs, it may progress to pneumonia due to secondary infections.


HOW IS IT SPREAD?

The virus is spread through aerosolized secretions (coughing, and sneezing), through fomites (toys, food and water bowls, etc.) and through direct dog to dog contact.

CIV is most easily spread in high population environments such as shelters, boarding centers, dog shows, pet stores, dog parks, veterinary hospitals, and grooming facilities.

Infection can occur within a few hours of exposure to the virus, and illness may manifest within 2 to 4 days of infection. Infected dogs may not appear sick but may still be contagious to other dogs. The H3N8 virus may shed for up to 10 days, while the H3N2 virus may shed for up to 24 days.


WHAT SHOULD I DO?

In the face of an outbreak, avoid high risk environments such as kennels, dog shows, and dog parks. At this time, we have had no known outbreaks at Ocean Reef.

If your dog becomes ill, seek veterinary care. Many different viruses and bacteria can cause similar clinical signs. Isolate sick dogs for 21 days from the onset of clinical signs.

The virus can persist in the environment for about 2 days but is sensitive to routine disinfectants such as 1:30 dilution of bleach.

 

IS THERE A VACCINE?

Vaccines are available for each subtype of the Canine Influenza virus: H3N8 and H3N2. Vaccines decrease the severity and degree of illness and viral shedding.

Each subtype requires an initial vaccination followed by a second vaccination within 2 to 4 weeks. After that annual boosters are recommended.

Onset of significant immunity may take up to 1 week after the second booster.  A single vaccine is unlikely to be protective for dogs initially entering a boarding facility. Plan accordingly if you need these vaccinations for boarding.


IS IT CONTAGIOUS TO HUMANS?

No known transmission to humans has occurred.


HOW DO I GET VACCINATIONS FOR MY DOG?

We currently offer a bivalent vaccine for both subtypes of the Canine Influenza Virus at the Grayvik Animal Care Center. With this combination vaccine only 2 shots within 2 to 4 weeks of each other are required. Annual revaccination is recommended.


If you feel like your dog is at risk due to their lifestyle or if you have any additional questions, please contact us at the Grayvik Animal Care Center.
