Fever of unknown origin.

This is a case study of a 26-year-old Hispanic male who presented with an initial complaint of fevers, chills and generalized weakness for three weeks. Patient reported a classical history of diurnal fever with temperature spikes as high as 105.8F after returning from a trip to Guatemala. His symptoms had waxed and waned for 3 weeks. This case study will focus on the initial presentation, value of complete history and physical exam, use of laboratory data and use of specialized diagnostic procedures in the outpatient setting. This case proves to be highly relevant to primary care in the context of treating patients with fevers of unknown etiology. Primary care physicians should be alert for unusual diseases in patients who are returning from foreign travel. Malaria is a potentially fatal disease that can be acquired by travelers to certain areas of the world, primarily developing nations. Transmitted through the bite of the Anopheles mosquito, malaria usually presents with fever and a vague systemic illness. The disease is diagnosed by demonstration of Plasmodium organisms on a specially prepared blood film. This case study speaks to the importance of prompt work up and treatment of fever of unknown origin that presents in an unusual clinical picture or that is not readily explainable.
