Abstract：Objective To investigate and analyze the epidemiological characteristics of animal plague in Siziwang banner, Ulanqab, Inner Mongolia, China from 2009 to 2019, and to provide a basis for scientific prevention and control of plague. Methods Surveillance was performed on the plague in Jiang'an sum and Honggor sum and their surrounding areas according to the Plague Monitoring Scheme of Inner Mongolia from April to November each year from 2009 to 2019. The rodent density was investigated using the trap-on-the-day method with bow-shaped clamps, nocturnal rodents were investigated using the 5-meter clamp method, and the fleas were captured by grooming. According to the diagnostic criteria for plague (WS 279-2008), etiological tests were performed on the testable materials from the rodents and fleas, and serological tests were performed on the blood samples of the rodents using indirect hemagglutination assay. Results During 2009-2019, the mean rodent density was 2.30 mice/hm2 in the plague foci of Siziwang banner, Ulanqab, with the density of Meriones unguiculatus being 1.71 mice/hm2. The capture rate of nocturnal rodents was 1.96%. The flea infestation rate of rodents was 27.37% and the total flea index was 1.55. Seventeen positive rodents and 32 positive fleas were found by the etiological tests. Sixty positive serum samples were found by the serological tests. Conclusion The epidemic of animal plague in Siziwang banner, Ulanqab is active from 2009 to 2019, with a potential new round of epidemic peak in the future. Plague surveillance should be strengthened to prevent prevalence of human plague.
