A fever of unknown origin is a fever for which the cause has not yet been determined. If a patient has a red, sore throat with white exudate, swollen glands on the side of the neck, and a fever, the clinician may presume he knows that the origin of the fever is strep throat. If a patient has a fever without "localizing symptoms" -- that is, symptoms that point to a body part that's affected/infected -- it may be called a fever of unknown origin, or FUO.
Fever of unknown origin (FUO) refers to the presence of a documented fever for a specified time, for which a cause has not been found after a basic medical evaluation.
