Helping Shelters Respond to H3N2 Canine Influenza

In March and April of 2015 a novel strain of canine influenza, H3N2, was identified during an outbreak of canine respiratory disease in Chicago, IL. Our University of Wisconsin Shelter Medicine Program has partnered with many other agencies to uncover valuable information about managing and limiting the impact of this new virus.

Dr. Sandra Newbury and the UW Shelter Medicine Program team continues to work to help shelters respond to the many challenges this new respiratory disease has presented. The support we provide to shelters concerned about any outbreak affecting their animals involves diagnostics as well as advice on management, and ways to minimize the impact for the animals as well as the shelter’s resources. Our continued studies and outreach education in the field have led to a better understanding of treatment, the risks of infection, and management of the disease in shelters.
