Conclusions: Ixodid ticks maintain the virus of this disease for a long time, and are essential members of biocenosis of a natural focus of hemorrhagic fever; the existence of a natural focus of hemorrhagic fever is apparently associated with the presence of at least two ixodid tick species (Dermacentor pictus Herm. and Dermacentor marginatus Sulz.) encountered in the western Siberian lowlands. Direct contact with ixodid ticks appeared to be a determining, but possibly not the only factor in occurrence of this disease among humans. The existence of natural foci of hemorrhagic fever is probable within the distribution range of two ixodid tick species throughout the entire extent of the western Siberian lowlands, in any case within the boundary of southern subzone of the taiga and steppe zone of Omsk Oblast.
