This tick mainly parasitizes carnivores such as raccoons, foxes, and mustelids across North America (Bishopp & Trembley 1945, Durden & Keirans 1996). Ixodes cookei is a vector of Powassan encephalitis virus in the northeastern US (Main et al. 1979), but the vector potential of this tick and status of the virus in the GSMNP has not been studied.
