Abstract:
Objective To analyze the monitoring results of plague in Qianxi'nan Prefecture in Guizhou Province from 2006 to 2015,and to provide a reference for prevention and control of plague.Methods Using a retrospective analysis method,plague epidemic reports,epidemic source investigations,and animal plague surveillance data from 3 monitoring sites in Xingyi City,Anlong County,and Yilong Experimental Area in Qianxi'nan Prefecture from 2006-2015 were collected and analyzed.Results In 2006-2015,no rat plague and human plague occurred in Qianxi'nan Prefecture.There was no Yersinia pestis,and a total of 1 plague antigen F1 positive rat was detected in Xingyi City in 2006.The density of indoor rat was 2.28％ (3 580/157 192),the density of indoor Rattus flavipectus was 1.31％ (2 052/157 192),ranging from 0.90％ to 1.82％,the differences were statistically significant between different years (x2 =91.110,P ＜ 0.05);and the density of outdoor rat was 1.52％ (2 358/154 732),the density of outdoor Rattus flavipectus was 0.58％ (905/154 732),ranging from 0.39％ to 0.90％,the differences were statistically significant between different years (x2 =63.428,P ＜ 0.05).In the composition of rodents,Rattus flavipectus was the dominant species,Rattus norvegicus and Mus musculus were common species.The musk deer index was 1.19.In the composition of flea species,the Xenopsylla cheopis was the dominant species with an index of 0.64,Leptopsylla segnis and Monopsyllus anisus were common species.Conclusions Rattus flavipectus and Xenopsylla cheopis was the dominant rodent and flea species in Qianxi'nan Prefecture.The density of indoor Rattus flavipectus and the index of flea are higher than those of the national standard of plague control (1.0％,0.5).In the future,densities of Rattus flavipectus should be closely monitored,and the rodent and flea killing activities should be carried out in time.
