Abstract：Objective To analyze the clinical and epidemiological characteristics of brucellosis cases,and the potential transmission routes,so as to provide insights for brucellosis prevention and control.Methods A retrospective analysis was conducted on the clinical and epidemiological characteristics of personnel diagnosed with brucellosis and admitted to hospital between 2020 and 2023.Results From 2020 to 2023,a total of 7 cases of brucella infection were admitted,all male,aged 22-38 years.The initial symptoms primarily included fever,joint pain,or lower back pain.The time from symptom onset to diagnosis ranged from 2 to 11 months.Three cases exhibited skeletal system involvement,three showed urogenital system involvement,and one case presented with pneumonia and pericardial effusion.Epidemiological history revealed that two patients had contact with cattle or sheep at home,while one had a history of exposure to beef or lamb.Conclusion The persistently rising incidence of brucellosis may pose challenges to brucellosis prevention and control.Livestock farming or slaughtering activities of surrounding areas could be potential risk factors.The clinical manifestation of brucellosis is diverse and difficult to identify,and it is crucial for relevant institutions in epidemic areas to implement targeted brucellosis prevention and control measures based on the specific characteristics of their surrounding environments.
