Abstract:
Objective:To study the epidemiological characteristics of human brucellosis in Ordos City and provide reference and theoretical guidance for prevention and control of the disease.Methods:The surveillance data of human brucellosis cases and the serological surveillance data of key occupational populations reported by the Ordos City Center for Disease Control and Prevention from 2013 to 2022 were collected and analyzed descriptively. ArcGIS 10.8 software was used to draw a spatial distribution map of human brucellosis in Ordos City, and SPSS 26.0 software was used to conduct Spearman correlation analysis to further explore the impact of economic factors on human brucellosis.Results:From 2013 to 2022, a total of 8 676 cases of human brucellosis were reported in Ordos City, with an average annual incidence rate of 40.93/100 000. In 2022, 2 570 cases were reported, with an incidence rate of 116.78/100 000, reaching the peak in the past 10 years. The cases were mainly distributed in Dalad Banner, Hangjin Banner, and Otog Front Banner, with a total of 6 415 cases, accounting for 73.94% of the total number of cases. The spatial distribution spread from north to south and from north to east. The majority of cases were in the age group of 40 to 65 years old (6 061 cases, accounting for 69.86%), male (6 089 cases, accounting for 70.18%), and farmers and herdsmen (7 367 cases, accounting for 84.91%). The median time interval between onset and diagnosis was 16 days. The positive rate of serological surveillance in key occupational groups was 5.38% (7 058/131 229). The results of Spearman correlation analysis showed that the number of agricultural legal entities, the number of animal husbandry legal entities, regional gross domestic product, per capita disposable income of rural and pastoral residents, total agricultural output value, the number of cattle and sheep at the end of the year, milk production, and mutton production were important factors affecting the incidence of brucellosis ( P < 0.05). Conclusions:The incidence of brucellosis in Ordos City is on the rise, and the epidemic situation is severe. It is necessary to strengthen the surveillance and joint prevention and control of human brucellosis to prevent the spread and expansion of the epidemic.
