During 1983-84, 187 foxes, 37 coyotes, and 124 raccoons were trapped throughout the state of Wisconsin and their sera were tested for specific antibody to Canine Parvovirus-2 (CPV-2), Canine Distemper Virus (CDV), and Infectious Canine Hepatitis Virus (ICHV). Prevalence of antibody to CDV was 32 of 187 (17%) for foxes, 1 of 37 (3%) for coyotes, and 15 of 124 (12%) for raccoons. Prevalence of antibody to ICHV was 1 of 187 (0.5%) for foxes, 2 of 37 (5%) for coyotes, and 1 of 124 (1%) for raccoons. These results were similar to those found in previous studies. Prevalence of antibody to CPV-2 was 80 of 187 (42.2%) for foxes, 9 of 37 (24. 3%) for coyotes, and 19 of 124 (15%) for raccoons. There was a statistically significant relationship between age and the prevalence of CPV-2 for all species (p<0.05); significantly more adults had a positive titer than juveniles. Sex was not found a significant factor in determining prevalence in any of the 3 diseases. The geographic distribution of the 3 diseases was state wide and was related to population density.
