Current EpidemiologicaL Situation on Tularemia in the Northwestern Federal District of Russia

Abstract

Relevance. In Russia every year are registred 100 or more cases of tularemia, with about 70% of them in the Central, Northwest and Siberian federal districts. Goal. Assessment of the current epidemiological situation on tularemia in the North-West Federal district (NWFD). Materials and methods. By means of a MapInfo Professional-10,5 GIS-package information on selection of cultures of the activator of a tularemia and the recorded incidence was transformed to the database on the basis of which GIS layers were created. Definition of geographical coordinates of places of isolation of cultures of a tulyaremiyny microbe from biological objects in the territory of the NWFD is carried out by means of the GoogleEarth program. Results. In 2001 - 2015 in NWFD incidence observed in all regions of the district, except Novgorod and Pskov regions. But the analysis of incidence of a tularemia allowed to reveal the sick people who infected in the territory of these regions that means there regions is endemic of tularemia. There remains a strong tendency to increase the incidence of tularemia urban population.The lack of permanent monitoring of natural eyes of tularemia in some regions of the district, does not allow to trace the development of epizootic process and to assess the intensity and magnitude of epizootics. As a result, activation of natural foci of tularemia is not noted, which increases the risk of human infection in these areas. Conclusions. Insufficient or complete lack of vaccination of people against tularemia living in areas enzootic for this infection may lead to complication of the epidemiological situation.
