Influenza updates: Dogs in several more states infected with H3N2 canine influenza

July 20, 2015

Canine influenza continues to crop up in cities and towns scattered across the U.S.. Scientists at Cornell's Animal Health Diagnostic Center (AHDC), Idexx Reference Laboratories, and several veterinary diagnostic laboratories across the country have pooled their data and updated H3N2 surveillance maps on July 10.

The map reflects the growing numbers of positive H3N2 cases that have been reported in the Atlanta area. Cases have now been detected in dogs from Georgia, Illinois, Indiana, California, Iowa, Minnesota, Wisconsin, Texas, Idaho, South Dakota, Missouri, Michigan, Ohio, Alabama, South Carolina, Maryland, New York, Massachusetts, New Jersey, and in North Carolina, where numerous cases have been diagnosed in the Asheville and Winston-Salem areas.

Scientists at the AHDC and at the Baker Institute are working to understand more about the virus responsible, investigating how the canine immune system reacts to the virus, and working with other institutions to create models of how the virus passes from dog to dog.
