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.
