Figure 2. Geographic distribution of (A) human (including 5 formalin-fixed samples not shown in Figure 1) and (B) terrestrial mammal cases identified by rabies virus variant isolated. Minimum length polygons delimiting human cases associated with Silver-haired Bats (clade 1) and Eastern Pipistrelles (clade 2) shown in (A) and superimposed in (B). (C) Prevalence of Lasionycteris noctivagans (Ln) and Pipistrellus subflavus (Ps) variants in regions delimited by clades 1 and 2. Prevalence of variants in bats was estimated from unpublished state public health department reports that determined the percentage of rabies-positive Silver-haired or Eastern Pipistrelle bats from the total number of bats submitted (7, unpub. data). Prevalence of L. noctivagans and P. subflavus variants in terrestrial mammals and humans is estimated as the percentage of all spillover cases in each clade region infected with L. noctivagans or P. subflavus.
