The annual incidence began to increase rapidly from 2014, the highest annual incidence in 2019 was 5.79/10 5. There were statistical differences between the incidence of different years (χ 2 = 900.40, P < 0.001). Human brucellosis cases in Xianyang City were mainly concentrated in dairy goat breeding counties, with a total of 571 cases reported, accounting for 66.09%.

The occupation was mainly farmers, accounting for 83.45% (721/864). There had been an increase in the proportion of scattered children, students and preschool children. The total serological positive rate was 3.14% (283/9 009) in Xianyang City, and pathogenic culture showed variant strains. The median of interval between onset time and diagnosis time was 8 days. Conclusion:The prevalence of human brucellosis in Xianyang City, Shaanxi Province shows an overall upward trend, which needs to be paid more attention to and control efforts should be strengthened.
