Fever of unknown origin: Indian perspective

Adrija Hajra, Dhrubajyoti Bandyopadhyay


Fever remains a notorious problem for both patients as well as the doctors. In most of the cases the cause is specific but sometimes it becomes a great problem for the sufferer and the care giver. Fever of unknown origin (FUO) is defined as 1. Fever >38.30 C (1010F) on at least two occasions, 2. Illness duration of > or =3 weeks, 3. No known immunocomprimised state, 4. Diagnosis that remains uncertain after a thorough history-taking, physical examination, and some obligatory investigations.
