Modern Epidemiological and Epizootiological Situation on Ixodic Tick-Borne Borreliosis in the South of the European Part of Russia

The aim is to analyze the current epidemiological and epizootiological situation on ixodic tick-bome borreliosis in the South of the European part of Russia. Materials and methods . The research materials were the epidemiological and epizootiological data for 2014-2018 provided by the Rospotrebnadzor Departments, the Hygiene and Epidemiology Centers of the North Caucasian and Southern Federal Districts, and regional anti-plague institutions: Stavropol, Volgograd and Rostov-on-Don research anti-plague institutes, Astrakhan, Dagestan, Kabardino-Balkar, Black Sea, North Caucasus, Elista plague control stations, as well as the plague control station of the Republic of Crimea. The data of scientific publications on epizooitological monitoring, the species composition of vectors and agents of tick-borne borreliosis involved in the epizootic and epidemic process in the region were studied. In the study descriptive, analytical epidemiological methods, retrospective epidemiological and cartographic analyzes were used. Results and discussion . It has been noted that in 1999, the incidence of tick-borne borreliosis in the South of the European part of Russia, has occurred in 11 of the 15 administrative regions. The incidence of tick-borne borreliosis in the Republic of Kalmykia, has not been recorded since 2007, in the Chechen Republic - since 2014. To clarify the sources of tick-borne borreliosis infection in the territory of the Krasnodar and Stavropol Territories, the Volgograd and Rostov Regions, the Republic of Dagestan and the Karachay-Cherkess Republic, and also, to determine the boundaries of natural and natural-anthropurgic foci of ixodic tick-borne borreliosis constant epizootiological monitoring is required. In addition, it is necessary to create a unified algorithm for monitoring natural foci, to analyze data using modern geographic information and statistical tools.
