We report on the clinical, epidemiologic, and laboratory characteristics of the first case of human ehrlichiosis acquired outside the United States caused by an sp. other than . The patient, a 24-year-old woman, presumably acquired the infection in Mali in northern Africa; the diagnosis was made when she returned to North America. The patient reported a fever and diarrhea a week before she left Mali; the diarrhea resolved, but the fever and chills continued. She also reported intermittent tingling in both hands and feet and muscle discomfort. Her temperature was 37.8°C and her pulse rate was 100 per minute. She had two erythematous maculopapules (0.5 × 0.7 mm) on her thigh and ankle that resembled infected insect bites. Her hemoglobin level was 148 g/l with normal indices, and her white blood cell count was 10, 500/mm with many atypical lymphocytes and platelets. This report is intended to increase physicians' awareness of ehrlichiosis in foreign travelers and other patients, and suggests the need for further research to determine the prevalence and distribution of this disease.
