Epidemiological Situation on Natural Focal Infectious Diseases in the Territory of the North-Caucasian Federal District in 2015

Abstract

Objective of the study is to analyze epidemiological and epizootiological manifestations of natural-focal infections in the territory of the North-Caucasian Federal District (NCFD) in 2015. Materials and methods. Utilized were the reports of the Rospotrebnadzor Administrations, “Centers of Hygiene and Epidemiology” in the NCFD entities, Stavropol Research Anti-Plague Institute, Dagestan and Kabardino-Balkaria Plague Control Stations. Data processing was conducted using Excel Microsoft ware. Results and conclusions. Identified have been 8 nosological forms of natural-focal infections, including infections of bacterial etiology – 6 (75 %), and viral etiology – 2 (25 %). The majority of patients (164) are identified in the Stavropol Region: 67 (intestinal yersiniosis), 43 (Crimean–Congo hemorrhagic fever), 40 (Lyme borreliosis), 9 (leptospirosis), 2 (pseudotuberculosis), 1 (rabies), 1 (human granulocytic anaplasmosis) and 1 (human monocytic ehrlichiosis). The patients with 2 nosological forms of natural focal infections are identified in the Republic of Dagestan: 2 – Crimean–Congo hemorrhagic fever and one patient – tularemia. Also 2 nosological forms of natural focal infections are revealed in the Republic of Karachay-Cherkessia: one case of leptospirosis and one case of Crimean–Congo hemorrhagic fever (imported from the Stavropol region). 8502 field samples have been tested for the presence of markers of 12 nosological forms of natural-focal infections. Positive results for 10 of them have been obtained. The most comprehensive epizootiological monitoring has been carried out in the Stavropol Territory (10 nosological forms), whereat circulation of 8 pathogenic agents is registered.
