This topic will review the etiology, evaluation, and management of the otherwise healthy child 3 to 36 months of age with fever of less than 7 days duration. Fever in newborns, infants younger than 3 months, fever in immunocompromised patients, and fever of unknown origin (≥7 days) are reviewed separately:

(See "Clinical features, evaluation, and diagnosis of sepsis in term and late preterm infants" and "Management of the infant whose mother has received group B streptococcal chemoprophylaxis".)

(See "Febrile infant (younger than 90 days of age): Outpatient evaluation".)

(See "Fever in children with chemotherapy-induced neutropenia" and "Evaluation and management of fever in children with non-chemotherapy-induced neutropenia".)

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