ABSTRACT

Objective 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.Methods 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.Results 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 (x2 =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 (x2 =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.Conclusions 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 stricdy prevented.
