Seroprevalence (% exposed) of CDV and FPV subdivided by IgM and IgG antibody production among raccoons (a) over 3 years (IgM: n = 202; IgG: n = 197), and (b) over all 3 years combined and subdivided by age class (IgM: n = 199; IgG: n = 193). Light grey bar, FPV-IgM; open bar, FPV-IgG; dark grey bar, CDV-IgM; black bar, CDV-IgG.
