CRITERIA OF DIFFERENCE EVALUATION FOR VARIOUS TYPES OF HEMORRHAGIC FEVER WITH RENAL SYNDROME FOCI. HFRS FOCI IN VARIOUS BIOTOPES OF TYPICAL BARRENS

Abstract

Aim. Examine features of natural, natural-anthropourgic and anthropourgic foci of hemorrhagic fever with renal syndrome (HFRS) in various, mostly forest, biotopes of typical barrens due to differences of non-specific HFRS prophylaxis in foci of various types. Materials and methods. Epizootological and epidemiologic data from 1998 to 2012 were analyzed, gathered in HFRS foci of all types in Saratov area of Saratov Region (typical barrens). 14 606 trap-nights were worked off and 2669 small mammals were procured. The most significant population-ecologic and eco-logic-epizootological methods and criteria were used for comparative analysis of differences for 3 types of foci. Results. Based on analysis of multi-year data seasonal differences for HFRS foci of various types were shown by 10 population-ecologic and ecologic-epizootologic criteria. Conclusion. The results obtained allow to state that modern means and methods of non-specific prophylaxis of HFRS and other zoonoses in foci of various types different significantly. This allows the most rational use of material and financial resources.
