Distemper-infected raccoons have been discovered in the city of McMinnville.Local Animal Control officers are warning residents to stay clear of raccoons and have their pets vaccinated against the disease. The highly contagious, fatal disease is viral and affects the gastrointestinal, respiratory, and central nervous systems in dogs. Humans can contract an asymptomatic canine distemper virus, but if they have been immunized against measles, they are protected from CDV.According to McMinnville Public Works Department assistant director Brad Hennessee, city Animal Control officer David Denton trapped 26 raccoons, sent them for testing, and TWRA was notified that all of them tested positive for distemper.“Rabies was our concern,” said Hennessee.
