Approach to a Patient with Fever of Unknown Origin

Dr Katuramu Richard

Fever of Unknown Origin (FUO) is defined as a fever higher than 38.3ºC on several occasions, lasting for at least three weeks, with an uncertain diagnosis after one week of study in the hospital. The document categorizes FUO into various types and discusses common and rare causes, including drug fever and infections. It emphasizes the importance of a thorough diagnostic approach, including history-taking and physical examination, to identify underlying conditions. Additionally, it outlines the management strategies and the need for long-term monitoring of patients with undiagnosed FUO.
