In the first third of the twentieth century, the overgrazing of cattle in the eastern districts of the modern Rostov Province yielded deserts in the places of virgin steppes and created favourable conditions for the enlargement of an area for the small souslik, a main carrier of plague in the natural focus of the northwestern Caspian Sea Region. On the above territories, this gave rise to a new natural focus of plague. Its liquidation required many-year goal-oriented efforts of large collective bodies of plaguologists and great material costs. The settlements of small sousliks exist on the above territories today and the activation of a natural focus of plague in the adjacent Kalmykia generate a need for enhancing plague epidemiological surveillance in the eastern districts of the Rostov Province today.
在20世纪的前三分之一时间里，现代罗斯托夫省东部地区的过度放牧致使原始草原地区沦为沙漠，为小黄鼠（里海西北部地区自然疫源地鼠疫的主要传播者）的繁衍创造了有利条件。在上述地区，这引发了一个新的鼠疫自然疫源地。消除该疫源地需要鼠疫专家组成的大型集体机构多年来的目标明确的努力以及巨大的物质成本。如今，上述地区仍有小黄鼠栖息地，且相邻的卡尔梅克共和国鼠疫自然疫源地的活跃，使得如今罗斯托夫省东部地区加强鼠疫流行病学监测成为必要。
