Analysis of plague monitoring results from 2018 to 2020 in Guizhou Province / 中华地方病学杂志

ABSTRACT

Objective:To analyze the monitoring results of plague foci in Guizhou Province, to master the epidemic dynamics of the plague and to formulate the prevention and control measures.Methods:The plague monitoring data from 2018 to 2020 in Guizhou Province were collected from China Disease Prevention and Control Information System Plague Prevention and Control Information Management System to analyze the plague epidemic situation. The murine animals capture methods used were cage clip method, 5 m cage clip method and day-by-day rodent capture method. Bacterial culture and hemagglutination were used in laboratory.Results:A total of 2 273 murine animals were captured indoors with cage clip method, and the Rattus norvegicus was the dominant species, accounting for 47.29% (1 075/2 273), Rattus flavipectus and Mus musculus were common species, accounting for 43.55% (990/2 273) and 5.10% (116/2 273). A total of 1 460 murine animals were captured outdoors with 5 m cage clip method, and the Rattus rattus sladoni was the dominant species, accounting for 35.48% (518/1 460), Rattus flavipectus and Eothenomys miletus were common species, accounting for 16.03% (234/1 460) and 8.70% (127/1 460). A total of 5 742 murine animals (including 3 733 animals captured with cage clip method and 5 m cage clip method, 2 009 animals captured with day-by-day rodent capture method) were examined and 1 176 with flea, the flea infestation rate of murine animals was 20.48%, Xenopsylla cheopi was the dominant flea species [56.63% (3 020/5 333)] and the index was 0.53. Laboratory test results were all negative. Conclusions:The plague foci of Guizhou Province is at a quiescent stage, but the reignition cannot be ruled out. The monitoring of plague should be strengthened, the quality of the monitoring should be improved, and health education and publicity should be carried out to prevent the occurrence of human plague outbreaks.
