Fever is the most common symptom and sign of brucellosis, occurring in 80-100% of cases. It is intermittent in 60% of patients with acute and chronic brucellosis and undulant in 60% of patients with subacute brucellosis. Fever can be associated with a relative bradycardia. Fever of unknown origin (FUO) is a common initial diagnosis in patients in areas of low endemicity. [28] It is associated with chills in almost 80% of cases.
