RESUMO
AIM: Analyze HFRS morbidity in Russian Federation during the last 25 years (1990 - 2015). MATERIALS AND METHODS: Official statistics of Federal Service for Surveillance on Consumers' Rights Protection and Human Weillbeing (CPS), including Federal Centre of Hygiene and Epidemiology, were used for the analysis, as well as materials from regional departments of CPS and centers of hygiene and epidemiology. Epidemiologic analysis was the main method. Statistical treatment of the results obtained was carried out using gener- ally accepted methods of variation statistics with elements of system analysis. Results; For the studied period (1990 - 2015) 194 116 cases of HFRS were registered. Morbidity was registered in 8 federal districts of the Russian Federation in 58 subjects. The most intense epidemiologic situation was noted in Privolzhsky Federal District, that accounted for 86.4% of total HFRS morbidity during the -studied period. Analysis of morbidity was carried out in every federal district, most epidemically unfavorable territories are shown. CONCLUSION: The data presented on HFRS morbidity reflect -unfavorable situation for this disease in Russian Federation. Measures to prevent the emergence of diseases to reduce the general level of morbidity in Russian Federation are presented.

The territorial spread of Tahyna, Batai, Sindbis, West Nile fever and Crimean-Congo hemorrhagic fever viruses throughout the Saratov region in 1998 - 2000 was analyzed. The characteristics of the epizootic activity of the natural foci of these arboviruses in different landscape zones (temperate forest-steppes, steppes and semi-deserts) were calculated. The species composition of small mammals, the natural reservoirs of the causative agents of arbovirus infections, was determined.

Cases of cholera in the Derbent District of the Daghestan took predominantly mild and moderate clinical forms. The ratio of patients to Vibrio carriers was 1:1.25. The etiological agent of the epidemic was V. eltor, serovar Ogawa. Cholera patients were of greater epidemiological importance as the sources of infection in comparison with Vibrio carriers. Carrier state after convalescence was observed in 1.1% of cases. The population was infected with cholera, as a rule, through everyday contacts and in more rare cases by the water route. The highest rate of contamination with V. cholerae was registered in the age group of 0-2 years.

The epidemic of cholera in the Derbent District of the Daghestan was imported into the region. 172 cholera patients and 204 Vibrio carriers were registered in 23 settlements of the region during the period of June 26 to October 12, 1994. The wide spread of this infection was facilitated by high migration activity of the population and the belated introduction of measures for limiting migration. The most severe outbreaks of cholera were observed in Derbent and in the villages of Mamedkala and Morskoe.
