Abstract

The research deals with the assessment of the epidemiological and epizootic situation in the Vladimir region, concerning natural focal infections in the context of agricultural activities. The retrospective analysis of statistical data on morbidity anthropozoonoses taken from the Report forms №2 “Information on infectious and parasitic diseases” FBUZ “Hygiene and Epidemiology Center in Vladimir region” of Rospotrebnadzor Department of the Vladimir region during the period of 1958 – 2016. The study of the biological material in respect of pathogen the natural focal infections were conducted in the laboratory of natural-focal and especially dangerous infections FBUZ “Hygiene and Epidemiology Center in Vladimir region” Rospotrebnadzor Department of the Vladimir region. The following natural-focal diseases have been stated to be registered as important in the context of agriculture in the Vladimir region: hemorrhagic fever with renal syndrome (HFRS), leptospirosis and tularemia. HFRS domonates in the morbidity structure. Annual laboratory tests of the biological material regarding the pathogens of natural focal infections indicate the presence of epizootics among mouse-like rodents, red vole (M. glareolus) being the dominant species among them. The ratio of HFRS male to female is approximately 3 to 1 Positive results of the laboratory studies indicate epizootic activity and constant risk of exacerbation of the epidemic situation regarding zooanthroponotic infections, and zero human morbidity during a number of years does not speak of the attenuation of the natural infection focus and the basis for stopping the preventive measures.
