Abstract
We present the case of a young female health worker, resident in a high Andean region of Peru, with recent exposure to farm animals and arthropods, who developed acute febrile undifferentiated syndrome, severe thrombocytopenia and pulmonary and abdominal extravasation. Subsequently, the patient developed meningitis and early onset bilateral neurosensorial hypoacusis and showed reactive serology to acute infection by Rickettsia sp. Epidemiological and clinical considerations in the differential diagnosis for early management are discussed.
