Fever of unknown origin (FUO) refers to a condition in which the patient has an elevated temperature (fever) for which no cause can be found despite investigations by one or more qualified physicians. If the cause is found, it is usually a diagnosis of exclusion, eliminating all possibilities until only the correct explanation remains.
