Diagnostic Criteria
In 1961, Petersdorf and Beeson suggested the following criteria:[1][2]
- Fever higher than 38.3°C (100.9°F) on several occasions
- Persisting without diagnosis for at least 3 weeks
- At least 1 week's investigation in hospital
Classification
In 1991, Durack and Street proposed a revised definition in which cases of FUO are categorized into four subclasses: classic FUO, nosocomial (health care-associated) FUO, neutropenic (immune-deficient) FUO, and HIV-related FUO.[3]
Classic FUO
Fever (>38.3° C or >100.9° F) for >3 weeks with no identified cause after 3 days of hospital evaluation or ≥3 outpatient visits
Nosocomial (health care-associated) FUO
Fever (>38.3° C or >100.9° F) in hospitalized patients receiving acute care and with no infection present or incubating on admission if the diagnosis remains uncertain after 3 days of appropriate evaluation
Neutropenic (immune-deficient) FUO
Fever (>38.3° C or >100.9° F) in patients with immunodeficiencies if the diagnosis remains uncertain after 3 days of appropriate evaluation, including negative cultures after 48 hours
Fever (>38.3° C or >100.9° F) for >3 weeks in outpatients with confirmed HIV infection or >3 days in inpatients with confirmed HIV infection if the diagnosis remains uncertain after appropriate evaluation
