Population Status of Secondary Carriers in Natural Foci of Plague of North Caucasus for the Period 2012-2017
The paper presents the analysis of the population dynamics of secondary carriers of plague in the Northern Caucasus for the period 2012-2017. The data of the epidemiological survey carried out in four different natural plague foci - littoral sandy, the Dagestan plains and Piedmont, East-Caucasian high-mountain and Central-Caucasian high-mountain - are processed. It is shown that in all studied foci from 2012-2017, the number of secondary carriers was estimated as low and average. The indicator did not reach high and very high values. The population status of secondary carriers in the considered foci had minimal epidemiological significance. At the same time, monitoring and control of their number is necessary since the involvement of secondary carriers of the plague agent in the above-described foci will indicate a high intensity of plague epizootics.
