Abstract:
Objective:This study aims to analyze the epidemic situation and characteristics of human plague in Inner Mongolia Autonomous Region, in order to provide scientific basis for formulating human plague prevention and control strategies.Methods:The epidemic data of human plague in Inner Mongolia Autonomous Region from 1970 to 2022 were collected, and descriptive analysis of its distribution, sources of infection and route of transmission, and case classification were conducted. The epidemic data came from the Plague Prevention and Control Management Information System form the Chinese Center for Disease Control and Prevention, as well as the summaries of plague surveillance work from 1970 to 2022, the compilation of historical data and other relevant materials in Inner Mongolia Autonomous Region.Results:From 1970 to 2022, all cases of human plague in Inner Mongolia Autonomous Region occurred in the plague foci of Meriones unguiculatus, with 18 cases of disease and 5 deaths, and the case fatality rate was 27.78%. In 2019, there were 4 cases. Three cases each in Sunitezuo Banner, Wulateqian Banner, and Etuokeqian Banner. Two cases each in Wulatezhong Banner and Siziwang Banner. One case each in Shangdu Banner, Suniteyou Banner, Xianghuang Banner, Damao Banner, and Etuoke Banner. May, and from July to November, the number of cases was 4, 4, 4, 1, 2, and 4. Of the 18 patients, 13 were males and 5 were females, age ranging from 6 years to 70 years. Three patients aged 1 - 18, 11 patients aged 19 - 59, and 4 patients aged 60 - 70. The largest number of patients (13 cases) were pastoralists by occupation, followed by field workers (3 cases). Thirteen patients contracted the disease through flea bites. Among the plague subtypes, bubonic plague was the most common with 13 cases.Conclusions:From 1970 to 2022, patients with human plague in Inner Mongolia Autonomous Region were predominantly young adult males. Herdsmen and outdoor workers were more susceptible to human plague. The most common mode of transmission was through flea bites, and the predominant subtype of plague was bubonic plague.
