Abstract:
Objective:To study the changing trend of brucellosis epidemic in Taiyuan City, Shanxi Province from 2004 to 2022, and to provide reference for formulating brucellosis prevention and control policies.Methods:Through the China Disease Prevention and Control Information System, the epidemic data of human brucellosis with the onset time from January 1, 2004 to December 31, 2022 and the current address in Taiyuan City were collected. Descriptive epidemiological methods were used to analyze the temporal, regional, and population distribution characteristics of brucellosis.Results:From 2004 to 2022, a total of 1 834 cases of brucellosis were reported in Taiyuan City, with an average annual incidence rate of 2.25/100 000. The incidence rate of brucellosis in each year showed a fluctuating upward trend (χ 2trend = 428.04, P < 0.001). The onset time was mainly concentrated from February to August, accounting for 76.94% (1 411/1 834) of the total cases, with May being the peak month (283 cases). The incidence rate of brucellosis in all counties (cities and districts) ranged from 0 to 38.37/100 000, with the highest incidence rate in Loufan County in 2021. There were 1 470 males and 364 females, with a male-to-female ratio of 4.04 ∶ 1.00. The age range was 1 to 95 years old, among which the 1 - 29 age group accounted for 14.29% (262/1 834), the 30 - 39 age group accounted for 13.14% (241/1 834), the 40 - 49 age group accounted for 21.05% (386/1 834), the 50 - 59 age group accounted for 27.54% (505/1 834), and the 60 - 95 age group accounted for 23.99% (440/1 834). The main occupation was farmers and herdsmen, accounting for 67.23% (1 233/1 834). Conclusion:From 2004 to 2022, the epidemic of brucellosis in Taiyuan City shows a fluctuating upward trend, with males, middle-aged and elderly people, and farmers and herdsmen as the main affected population.
