ABSTRACT
Crimean hemorrhagic fever (CCHF) was rst recognized in 1944, as an acute febrile illness, accompanied with severe bleeding in over 200 cases who were bitten by ticks, in the Steppe region of western Crimea. Subsequently, it was shown that the virus was antigenically identical to the Congo virus, which was isolated from a febrile patient in Democratic Republic of Congo in 1956 and the combined name CrimeanCongo hemorrhagic fever virus has been used since the late 1970s [1].
