Y1 - 2017 N1 - T2 - Harrison's Infectious Diseases, 3e AB - Clinicians commonly refer to any febrile illness without an initially obvious etiology as fever of unknown origin (FUO). Most febrile illnesses either resolve before a diagnosis can be made or develop distinguishing characteristics that lead to a diagnosis. The term FUO should be reserved for prolonged febrile illnesses without an established etiology despite intensive evaluation and diagnostic testing. This chapter focuses on classic FUO in the adult patient. SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/19 UR - accessbiomedicalscience.mhmedical.com/content.aspx?aid=1141405089 ER -
