Fever in infants and children: Pathophysiology and management

Mark A Ward, MD
Section Editor

Deputy Editor
Mary M Torchia, MD


Fever is an abnormal elevation of body temperature that occurs as part of a specific biologic response that is mediated and controlled by the central nervous system.

The pathophysiology and treatment of fever in infants and children will be reviewed here. Other causes of elevated body temperature in children and the evaluation and management of fever in specific populations of infants and children are discussed separately:

(See "Heat stroke in children" and "Heat illness (other than heat stroke) in children".)

(See "Febrile infant (younger than 90 days of age): Outpatient evaluation" and "Fever without a source in children 3 to 36 months of age".)

(See "Management of fever in sickle cell disease".)
