Specialist: Although true fevers of unknown origin are considered by some to be fevers of 3 weeks duration that are undiagnosed while being tested in a hospital or as an outpatient for at least 2days, I recommend that you consult a specialist in infectious diseases for evaluation at this time. Appropriate and thorough testing will be done. Many such fevers turn out to be from noninfectious causes.

FUO: Is considered to be after about 3 weeks, time at which most lingering infections should fade away. Among causes for FUO, autoimmune disorders, malignancies and drug induced are among the most common.
