Objective To understand the enzootic plague epidemic characteristics of Inner Mongolia Spermophilus dauricus plague natural foci in the ChaHaEr hill-Song Liao plains during 2001-2013, provided a scientific basis for future plague surveillance and management. Methods Collected plague monitoring data from 2001 to 2013 in the Inner Mongolia S. dauricus plague natural foci, used descriptive epidemiological method to analyze the data. Results From 2001 to 2013, 18 937 S. dauricus were captured, rat density was 0.88; In total 38 203 S. dauricus were combed for fleas, flea infection rate was 48.60%. Together 76 452 fleas were collected, fleas index was 2.00;One strain Yersinia pestis was identified from Meriones unguiculatus and 93 positive serum samples of S. dauricus were detected by IHA from 2001 to 2013. Conclusion Enzootic plague persists in natural foci which is mainly maintained by S. dauricus, while there has been no human cases reported.
