Abstract
This retrospective cohort study aimed to identify predictors for focal disease in human brucellosis. The study included patients with brucellosis diagnosed between January 2000 and December 2021. Overall, 247 patients were identified. Focal disease was diagnosed in 64 (25.9%) patients. The most common focal infection was bone and joint in 56 patients (23.4%). Disease duration > 14 days was significantly associated with focal illness [OR = 2.2 (1.08–4.47), p = 0.030], although febrile illness was inversely associated with focal illness this did not reach statistical significance [OR = 0.46 (0.21–1.00), p = 0.050]. Focal brucellosis should be suspected in patients with prolonged illness.
