[Crimean-Congo haemorrhagic fever in southern Russia].

At the end of the 20th--the beginning of the 21st century activation of a natural focus of Crimean-Congo haemorrhagic fever (CCHF) in southern Russia was noted. As a consequence, in 2002 outbreaks and sporadic cases of this disease were registered on the territory of 6 out of 13 administrative units of the Southern Federal District. To minimize the epidemiological consequences of the aggravating epidemiological situation considerable efforts and means were required from health care organs and institutions of the state sanitary and epidemiological service, including essential financial expenditures. The results of natural foci of CCHF survey, obtained by 2002, as well as main trends of prophylactic and antiepidemic interventions are presented. Scientific research and practical observations made it possible to work out a number of methodological regulations concerning the diagnostics, treatment and prophylaxis of CCHF.
