Fever is a common presenting complaint in children. Most febrile illnesses either resolve before a diagnosis can be made or develop distinguishing characteristics that lead to a diagnosis. Fever of unknown origin (FUO) refers to a prolonged febrile illness without an established etiology despite thorough evaluation.
An approach to the evaluation of FUO in children will be reviewed here. Causes of FUO in children, fever without a source, and fever in specific pediatric populations are discussed separately:To continue reading this article, you must log in with your personal, hospital, or group practice subscription.
