Abstract:
Objective:To analyze the epidemic characteristics of human brucellosis in Inner Mongolia Autonomous Region, and to provide a basis for formulating targeted intervention strategies and implementation measures.Methods:The data of brucellosis cases with onset date from 2014 to 2023 and current address in Inner Mongolia Autonomous Region were collected from the Chinese Disease Control and Prevention Information System. Descriptive epidemiological method was used to analyze the three-dimensional distribution of human brucellosis in Inner Mongolia Autonomous Region.Results:From 2014 to 2023, a total of 131 201 brucellosis cases were reported in Inner Mongolia Autonomous Region, with no death and an average annual incidence rate of 52.90/100 000. The lowest incidence was in 2016 (6 567 cases, 26.15/100 000), and the highest was in 2021 (21 910 cases, 91.14/100 000). All 12 cities (leagues) in the region had reported cases of brucellosis, with Tongliao City (27 012 cases), Chifeng City (15 286 cases), Hinggan League (14 859 cases), Hulunbuir (12 235 cases) and Ulanqab (11 972 cases) ranking among the top 5 cities (leagues) in terms of reported cases. Among the cases, 90 455 (68.94%) were males, with a incidence rate of 70.93/100 000, and 40 746 (31.06%) were females, with a incidence rate of 33.70/100 000. The age of onset is mainly 50 and less than 60 years old (37 610 cases, 28.67%). The occupational distribution was mainly farmers (102 091 cases, 77.81%), followed by herdsmen (13 209 cases, 10.07%).Conclusions:The incidence of human brucellosis in Inner Mongolia Autonomous Region is at a relatively high level, particularly showing an upward trend from 2016 to 2021. Cities such as Tongliao City, Chifeng City and Hinggan League have a relatively high incidence of brucellosis. Therefore, it is necessary to strengthen the monitoring of brucellosis in these areas, implement prevention and control measures, and closely monitor the changes in the trend of human brucellosis outbreaks. Farmers and herdsmen are the primary high-risk groups, and it is recommended to enhance health education and behavioral interventions for these key populations.
