[Ways to improve the epidemiological surveillance for plague].

The paper deals with the plague epidemiological surveillance in natural foci and with the ways of its improvement. The diversity of methods currently used for surveillance ensures a satisfactory epidemic situation though the problem of plague control among rodents and hares in the natural foci remained unsettled. Therefore the main task of research and practical plague institutions in improving plague epidemiological surveillance in the natural foci is to provide further research evidence for the application of facilities and guidelines to control the carriers and vectors of plague, which can prevent the development of epizootics and reduce a risk for human infection in the enzootic areas.
