Definition:

 Defined by Petersdorf and Beeson in

    1961:

  1. 1. Fever > 38.3 °C on several occasions
  2. 2. Duration of fever 3 weeks
  3. 3. Uncertain diagnosis after one week of

    study in the hospital

 Refinements of the definition have been proposed:
  1. 1. Elimintaing in-hospital evaluation requirement (since outpatient evaluation has become more

     sophisticated).

  1. 2. Expanding definition to include nosocomial
  2. neutropenic vs. HIV fevers that might

    not be prolonged

Undiagnosed FUO’s dropped from > 75% in

    1930’s to < 10% in 1950’s.
