The management of febrile infants younger than 90 days of age is discussed in this topic.
For a discussion of the outpatient evaluation of febrile infants younger than 90 days of age; definition of fever in the young infant; the diagnosis, evaluation, and initial management of fever and early-onset sepsis in neonates (younger than 7 days of age); and the approach to an ill-appearing infant without fever refer to the following topics:
