Objective: To determine the characteristics of febrile fullterm infants during the first days of life, and to discoverthe
rate of serious bacterial infections among low risk neonateswith
systemic fever.
Design: A retrospective case-control study of 122 cases and
122 controls in a single institution.
Results: Weight loss, breast feeding, caesarean section delivery,and high birth weight were found to be the most significant
predictors of developing fever during the first days of life.Of the
122 patients in the study group, only one had a seriousbacterial
infection (a positive urine culture for group B streptococcus).
Conclusions: In low risk full term infants, fever with no othersymptoms during the first days of life (but after the first
day) is related primarily to dehydration, breast feeding, caesarean
section, and high birth weight. Infection is the least common
explanation.
Keywords: fever, dehydration; breast feeding; caesarean section;
