To analyze the monitoring results on plague from 2013 to 2017 in Guizhou Province, to master the epidemic dynamics of the plague and to provide a basis for developing countermeasures.

Using a retrospective analysis method, plague monitoring data from 9 monitoring sites in Xingyi City, Anlong County, Ceheng County, Xingren County, Pan County, Liuzhi Special Zone, Si′nan County, Dejiang County and Yanhe County in Guizhou Province from 2013-2017 were collected and analyzed.

In 2013- 2017, there were no plague F1 antigen and F1 antibody. A total of 3 575 murine animals were captured indoors, with Rattus norvegicus as the dominant species, accounting for 49.99% (1 787/3 575). Rattus norvegicus and Mus musculus were common species, accounting for 35.64% (1 274/3 575) and 11.36% (406/3 575), respectively; the density of indoor rat was 3.48%(3 575/102 641), there was no significant difference in rat density between different years (χ²= 3.655, P > 0.05). A total of 1 674 murine animals were captured outdoors, and the Rattus norvegicus was the dominant species, accounting for 34.29% (574/1 674). S. serrata and Rattus norvegicus were common species, accounting for 18.28% (306/1 674) and 13.20% (221/1 674), respectively; the density of outdoor rat was 1.67% (1 674/100 180), there was no significant difference in rat density between different years (χ²= 6.241, P > 0.05). A total of 9 541 murine animals were examed and 2 270 rats with flea were detected, the flea infestation rate of rat was 23.79%, the rat body flea index was 1.019 4, Xenopsylla cheopi was the dominant flea species and the index was 0.557 3.

The plague natural focus of Guizhou is at a quiescent stage. The plague monitoring work should be strengthened, health education should be done well, and plague epidemics should be strictly prevented.
