Canine Influenza Outbreak
Here is the latest information regarding canine influenza and the recent outbreak:
Since March 14, 2015, there have been thousands of Chicago area dogs who have become sickened with respiratory disease. At first, we thought we were just dealing with CIRDC (Canine Infectious Respiratory Disease Complex, what many refer to as "Kennel Cough"). Then, after cultures showed that many of these dogs had Influenza A, we thought we were dealing with a subtype of influenza called H3N8 that has not been seen in the USA since 2004.
On April 12, 2015, Cornell University issued a press release that states that the ongoing canine influenza in the Chicago area is due to the H3N2 subtype of canine influenza, not the H3N8. This is the first identification of the H3N2 subtype outside of Asia.
At this point, it is unclear how the virus first arrived in Chicagoland. There seem to be "hot zones" of infection, and the highly contagious nature of the disease caused infection to spread from there. Dogs at greatest risk include those who spend time among large groups of other dogs: doggie daycare; pet stores; groomers; kennels; shelters; rescue groups; adoption centers; etc.. While some cats in Asia have become infected, they may or may not have been immunocompromised when exposed.
What we know is this:
**UPDATE**: If your dog is at-risk for canine influenza, we have the vaccine available to protect against the H3N2 strain (the new and recent strain causing the outbreak). Please call us to set up the first booster; the final dose would be given 3-4 weeks later. This vaccine is required to board at River Forest Animal Hospital. We'll keep you posted with new information as it comes along. If you're on Facebook, please find & like our page for regular pet health updates.
