Geographical distribution of selected tick-borne pathogens and diseases. All geographical boundaries are generalized and approximate. Abbreviations and descriptions are shown in Table 1. For some pathogens (Heartland virus, Thogoto virus, B. divergens, Ca. N. mikurensis), only country or state-level data were available. Only partial ranges are shown for some worldwide diseases and conditions – TBRF (tick-borne relapsing fever) in northwestern Africa, tick paralysis in Australia. Modified from previously published records and maps [29, 37, 44, 51, 53, 64, 66, 72, 83, 94, 105, 149–155]
