Abstract:
Objective:To analyze the epidemiological characteristics and risk factors of brucellosis in Yan'an City, and to provide a theoretical basis for scientifically formulating prevention and control measures for brucellosis.Methods:A descriptive analysis method was used to analyze the general information, epidemiological characteristics of confirmed brucellosis cases at General Hospital of Yan'an Second Medical Group from 2019 to 2023. Univariate and multivariate logistic regression models were used to analyze the risk factors for brucellosis infection in the population.Results:From 2019 to 2023, a total of 301 cases of brucellosis were confirmed, and the number of cases in each year was 1, 7, 85, 85 and 123 cases, respectively. There were 231 males and 70 females, with a gender ratio of 3.3 ∶ 1.0. The patients were mainly aged between 15 and 64 years old (88.70%, 267/301), with a higher incidence in summer and autumn (36.55%, 110/301; 30.23%, 91/301). The occupation was dominated by farmers (62.98%, 182/289). The area with the highest number of cases was Ansai District (20.67%, 62/300), followed by Baota District (19.33%, 58/300) and Zhidan County (17.67%, 53/300). The results of multivariate logistic analysis showed that contact with livestock and unprotected contact were risk factors for brucellosis infection ( OR = 2.81, 6.75, 95% CI: 1.14 - 5.98, 1.23 - 15.72, P < 0.05). Conclusions:From 2019 to 2023, the number of brucellosis cases in Yan'an has been increasing year by year, with a higher incidence among young and middle-aged people. Summer and autumn are the high incidence seasons for the disease, and Ansai District, Baota District, and Zhidan County are key areas for brucellosis prevention and control in Yan'an City. Failure to take protective measures when in contact with livestock can increase the probability of brucellosis infection.
