RESUMO
The tension of the rabies epidemiological situation in the regions of new constructions in Siberia and the Far East was the result of a wide spread of the infection foci and a great number of domestic animals affected by the disease. All over the territory the main-source of the infective agent for humans are dogs, and only in a few cases wild animals. In the mountainous and steppe regions of the south-eastern part of the Transbaikal territory a natural focus of rabies has been revealed. A scheme for dividing the territory into rabies epidemiological regions has been developed on the basis of studying the factors contributing to the dynamics of the epidemic and epizootic processes, as well as the epizootic situation (in the Chita and Amur regions used as an example).
