A study of 235 cases of human brucellosis in Sana'a, Republic of Yemen.

We studied the clinical characteristics of brucellosis among all patients with brucellosis referred to the Central Health Laboratory from the main hospitals in Sana'a during a 2-year period (1992-93) (235 adults and children). A history was taken from each patient and clinical examination, general laboratory tests and brucellosis laboratory tests carried out. The overall clinical picture of brucellosis in this study is very similar to that reported by other workers in this geographical area. Awareness of the presenting features and the realization that brucellosis should be part of the differential diagnosis of febrile patients with enlarged liver, spleen and lymph nodes will lead to an increasing index of suspicion for this disease.
