EPIDEMIOLOGICAL DIFFERENTIATION OF NATURAL FOCI OF HEMORRHAGIC FEVER WITH RENAL SYNDROME OF THE REPUBLIC OF BASHKORTOSTAN

Abstract

Aim. Typization of natural foci of HFRS of the Republic of Bashkortostan and differentiation of their territories by the degree of potential epidemic hazard. Materials and methods. Materials of epizootologic and epidemiologic monitoring of natural foci of HFRS of the Republic of Bashkortostan for 1980 - 2014 were used. Evaluation of area of territory with high, medium and low potential epidemic hazard by HFRS was carried out taking into account multi-year parameters of morbidity by administrative districts of the Republic of Bashkortostan. 3 gradations of morbidity level by HFRS - more than 201, 101 - 200, less than 100 per 100 thousand of the population - were used for epidemiologic differentiation of the territory. Results. 3 main landscape-epidemiologic types of HFRS foci were isolated - forest, forest-barrens, barrens, as well as their landscape variants. The area with a high degree of potential epidemic hazard by HFRS was established to be around 3.8%; medium - 15.9%, low - 80.3% of the whole territory of the Republic of Bashkortostan. Conclusion. A necessity of a differentiated approach to territories with various degree of potential epidemic hazard by HFRS is justified during execution of prophylaxis activities.
