Midwest Canine Influenza outbreak caused by new strain of virus

April 12, 2015 By Joe Schwartz

ITHACA, N.Y. – The canine influenza outbreak afflicting more than 1,000 dogs in Chicago and other parts of the Midwest is caused by a different strain of the virus than was earlier assumed, according to laboratory scientists at Cornell University and the University of Wisconsin. Researchers at Cornell say results from additional testing indicate that the outbreak is being caused by a virus closely related to Asian strains of influenza A H3N2 viruses, currently in wide circulation in southern Chinese and South Korean dog populations since being identified in 2006. There is no evidence that it can be transmitted to humans.

The outbreak in the Midwest had been attributed to the H3N8 strain of virus, which was identified in the U.S. dog population in 2004 and has been circulating since. The H3N2 virus had not been previously detected in North America. The outbreak in Chicago suggests a recent introduction of the H3N2 virus from Asia. (more…)

Update on the canine influenza virus H3N2

dog flu outbreak

We recommend the H3N2 canine flu vaccination for high risk patients.

There is currently a resurgence of H3N2 acute canine influenza cases occurring in our area.

We continue to see dogs that present with respiratory signs that test positive for the H3N2 virus. These dogs frequently have had recent communal contact with other dogs at doggy daycare or boarding facilities usually 2-5 days prior.

Anecdotally, we have noticed that patients that have been immunized with the conditional vaccine marketed by the pharmaceutical company Zoetis have demonstrated much less severe symptoms and course of disease.   Also, many previously immunized patients did not develop the disease following direct exposure as well.  Therefore, we do advise if you have any questions regarding the new canine influenza virus or immunization please give our office a call.

We recommend immunizing any high risk patients for the canine influenza virus.

Lastly, if you have dogs that live with cats in your home, some cats have been diagnosed with the canine H3N2 influenza virus and are at risk for also developing clinical signs.   Unfortunately, there is no immunization available for cats at this time.  If you have any questions regarding your feline friend, please give us a call.
