Definition
In 1961 Petersdorf and Beeson suggested the following criteria:
- Fever higher than 38.3°C (101°F) on several occasions
- Persisting without diagnosis for at least 3 weeks
- At least 1 week's investigation in hospital
A new definition which includes the outpatient setting (which reflects current medical practice) is broader, stipulating:
- 3 outpatient visits or
- 3 days in the hospital without elucidation of a cause or
- 1 week of "intelligent and invasive" ambulatory investigation.
Presently FUO cases are codified in four subclasses.

Famous quotes containing the word definition:
“The very definition of the real becomes: that of which it is possible to give an equivalent reproduction.... The real is not only what can be reproduced, but that which is always already reproduced. The hyperreal.”
—Jean Baudrillard (b. 1929)
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!—But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (1803–1882)
“According to our social pyramid, all men who feel displaced racially, culturally, and/or because of economic hardships will turn on those whom they feel they can order and humiliate, usually women, children, and animals—just as they have been ordered and humiliated by those privileged few who are in power. However, this definition does not explain why there are privileged men who behave this way toward women.”
—Ana Castillo (b. 1953)
