Abstract:
Objective:To study the epidemic characteristics of human brucellosis in Shandan County, Zhangye City, Gansu Province, and provide reference basis for formulating effective prevention and control measures.Methods:The surveillance data of brucellosis were collected from the China Disease Prevention and Control Information System and Shandan Center for Disease Control and Prevention to describe the three-compartment distribution (population, time, region distribution), and were analyzed by SPSS 19.0.Results:A total of 482 cases of brucellosis were reported with an average annual incidence of 48.99/100 000 from 2016 to 2021 in Shandan County, and farmers were the mainly occupation (84.85%, 409/482). The sex ratio of men and women was 3.16 ∶ 1.00 (366/116). The onset time was mainly concentrated in summer and autumn. Breeding cattle and sheep (feeding, cleaning pens, etc.) resulted in 107 cases of direct contact infection, accounting for 22.20% of the total cases (107/482). Incidence rate of different years was quite different (χ 2 = 121.09, P < 0.001). The average annual incidence rate of brucellosis in Laojun Township (95.72/100 000) was statistically different from that in other towns (χ 2 = 20.49, P < 0.001). Conclusions:The overall high prevalence of human brucellosis in Shandan County from 2016 to 2021. The animal husbandry department should strengthen the control of infectious sources, and the health department should increase publicity and education to curb the spread of the epidemic as soon as possible.
