APPROACH TO THE PATIENT WITH FEVER OF UNKNOWN ORIGIN: A DETAIL STUDY

Abstract

Fever of unknown origin (FUO) remains one of the most challenging clinical entities in medicine because of its broad differential diagnosis and the absence of a single diagnostic test capable of identifying the underlying cause. Many people eventually have common disorders that show atypically, even though infections, cancers, and noninfectious inflammatory diseases make for the bulk of instances. The cornerstones of evaluation continue to be thorough history taking, regular physical examinations, and a phased diagnostic approach. The majority of FUO cases are linked to common diseases that appear atypically, despite the extensive list of possible causes. A comprehensive clinical history and physical examination are part of the diagnostic procedure, which is followed by focused investigations based on preliminary results and local epidemiology. In the end, improving diagnostic yield, lowering healthcare expenditures, and improving outcomes for patients with FUO can be achieved by sticking to a methodical approach and avoiding needless empiric therapy.
