*CCHFV, Crimean-Congo hemorrhagic fever virus; NA, not applicable. †Genotypes: I, West Africa (Africa 1); II, Central Africa (Africa 2); III, South and West Africa (Africa 3); IV, Middle East/Asia, divided into groups Asia 1 and Asia 2; V, Europe/Turkey (Europe 1); VI, Greece (Europe 2). ‡Collected from wild boar. §In Castile-La Mancha, ticks of the same species but collected from different animals were mixed in a single tube, so it was not possible to determine the number of animals with positive ticks. ¶Collected from red deer.
