Figure 2. . Ranges (gray) of A) northern red-backed vole (Myodes rutilus), B) southern red-backed vole (M. gapperi), C) deer mouse (Peromyscus maniculatus), and D) piñon mouse (P. truei), United States, Russia, and Canada. Major range overlap between the 4 species found with deer-tick virus–reactive antibodies suggests that the responsible virus may have access to competent amplifying hosts throughout North America. Panel A was based on the International Union for Conservation of Nature and Natural Resources Red List (www.iucnredlist.org/) and panels B–D were based on the Smithsonian National Museum of Natural History, North American Mammals (www.mnh.si.edu/mna/main.cfm).
