[EPIZOOTOLOGIC MONITORING OF NATURAL-FOCAL INFECTIONS IN THE SOUTH OF RUSSIA IN 2015].

AIM: Analyze epizootologic manifestations of natural-focal infections (NFI) in the south of Russia in 2015. MATERIALS AND METHODS: Reports provided by administrations of Federal Service of Surveillance for Protection of Consumers Rights and Human Welfare, Centers of Hygiene and Epidemiology, Research Institutes for Plague Control and Station for Plague Control were used. Data processing was carried out using Excel program. RESULTS: A total of 37-738 samples of field material were studied, most of those - for tularemia (8268), Crimea hemorrhagic fever (6894) and West Nile fever (4875). Causative agents of 15 nosologic forms of NFI were detected during epizootologic examination of the territory of south of Russia, predominating amount of positive samples was obtained during study of material for tick-borne borreliosis (612), Crimea hemorrhagic fever (279) and tularemia (237). CONCLUSION: Analysis of epizootologic situation on natural- focal infections in the south of Russia gives evidence on the increase of activity of natural foci of bacterial (tularemia, tick-borne borreliosis), rickettsia (tick-borne spotted fevers) and viral infec- tions (Crimea hemorrhagic fever, West Nile fever, tick-borne viral encephalitis), and thus problems of prophylaxis of natural-focal infectious diseases and constant monitoring of natural foci in su- bjects of Southern, North-Caucasian and Crimea federal districts are of particular importance.

[EPIDEMIOLOGIC SITUATION BY NATURAL-FOCI INFECTIONS IN THE CRIMEA FEDERAL DISTRICT IN 2014-2015].

AIM: Analysis of epidemic manifestations of natural-foci infections (NFI), clarification of spectrum of their causative agents, determination of epizootic activity of natural foci in the Crimea Federal District (KFD). MATERIALS AND METHODS: Epizootologic examination of 10 administrative districts of KDF was carried out. 291 pools (2705 specimens) of ixodes ticks and 283 samples of organs of small mammals were studied by PCRmethod for the presence of DNA/RNA of causative agents of a number of NFI. RESULTS: Morbidity by NFI in KFD was registered by 6 nosologies: Lyme borreliosis, Marseilles fever, leptospirosis; tularemia, intestine yersiniosis and tick-borne viral encephalitis, wherein, transmissive infections made up 91.6%. Circulation of causative agents of Crimea hemorrhagic fever, Q fever, group of tick-borne spotted fever, Lyme borreliosis, human granulocytic anaplasmosis, human monocytic ehrlichiosis, hemorrhagic fever with renal syndrome, West Nile fever, tularemia and leptospirosis was established. CONCLUSION: Due to activity of natural foci of NFI further monitoring of epidemiologic and epizootologic manifestations of these infections in the Crimea, including using genetic methods of analysis, is necessary for ensuring sanitary-epidemiologic welfare of KFD population.

[PROCUREMENT OF SANITARY AND EPIDEMIOLOGICAL WELFARE IN THE REGION OF-CITY-RESORT SOCHI FOR DANGEROUS AND NATURAL-FOCI INFECTIOUS DIS- EASES IN 2015].

AIM: Analysis ofresults of epidemiologic monitoring especially dangerous, natural-foci and other infectious diseases, asill as epizootologic activity of natural foci of infection on,the terri- tory, of city-resort Sochi. MATERIALS AND METHODS: Laboratory studies of 820. samples by PCR; im- mune- and bacteriologic methods were carried out, among those 344 - clinical material, 12 - water from open bodies and 321 - field material. Molecular-genetic identification of-143 strains of Vibrio-cholerae, isolated from open water bodies of city-resort Sochi, was-carried out,. RESULTS: Circulation of causative agents of Q fever, tularemia and hemorrhagic fever with renal syndrome of Dobrava-Adler genotypes was established, -as well as rickettsia of tick spotted fever group Predomination of rotaviruses (70.9%) was detected during study of samples of clinical material in etiologic structure of sporadically emerging acute intestine infections. Relatively high temperature values of river water during summer months (from 18, to 30 C), exit of sulfide mineral waters into the riverbed, that create-alkaline medium, seasonal reduction of river debit and speed of water current facilitated sustenance of contamination of water of Agura river by V.cholerae. CONCLUSION: Activity of natural foci of the infectious disease and contamination of Agura iver by V.cholerae Ο1, (atoxigenic) gives evidence on the necessity of constant control of epidemiologic situation by dangerous and natural-foci infectious diseases on the territory of city-resort Sochi, as well as study regional features, of their causative agents, including using genetic methods.

[Analysis of foreign experience of maintenance of biological safety of the Olympic Games].

The analysis of the international experience in providing measures of health and disease safety at the Olympic Games was done. The stages of the formation of bio-security system at public events were considered, including measures to prevent infection outbreaks, the use of computer and information technologies.

[Using modern information technology in the practice of the sanitary-epidemiological surveiliance during the XXII Olympic Winter Games and XI Paralympic Winter Games in Sochi].

To improve the sanitary and epidemiological surveillance at the Olympic Games has developed a system of GIS for monitoring objects and situations in the region of Sochi. The system is based on software package ArcGIS, version 10.2 server, with Web-java.lang. Object, Web-server Apach, and software developed in language java. During th execution of the tasks are solved: the stratification of the region of the Olympic Games for the private and aggregate epidemiological risk OCI various eti- ologies, ranking epidemiologically important facilities for the sanitary and hygienic conditions, monitoring of infectious diseases (in real time according to the preliminary diagnosis). GIS monitoring has shown its effectiveness: Information received from various sources, but focused on one portal. Information was available in real time all the specialists involved in ensuring epidemiological well-being and use at work during the Olympic Games in Sochi.
