title: The infant with unexplained fever.
abstract: Managing the infant who has fever without an obvious source can be difficult. The clinician should know how the infant's age, temperature, degree of toxicity and white blood cell count relate to the risk of occult bacterial disease, particularly bacteremia. In many instances, presumed bacteremia can be managed initially with outpatient blood culture and antibiotics. Close follow-up and early reexamination are necessary if blood cultures are positive.
