“The new strain of canine distemper virus was identified by UNH pathologists in collaboration with colleagues at Cornell University, University of Georgia, Northeast Wildlife Disease Cooperative, N.H. Fish and Game, and Vermont Fish and Game. Over a one-year period, pathologists diagnosed canine distemper virus infection in eight largely carnivorous mammals in southeastern New Hampshire and north central Vermont. The animals included three fishers, two gray foxes, one skunk, one raccoon, and one mink.”
While this new strain may not be a risk for the rest of the country, it would be diligent to alert your veterinarian to the new distemper strain. According to the report a raccoon in Rhode Island was found to have it in 2004. This indicates that it is not new and has potentially spread. There is always the chance in time, it will spread across the country.
