This retrospective study was undertaken to evaluate the Rochester criteria for identifying febrile infants at low risk for serious bacterial infection. The Rochester criteria examines only infants who were born at term, had no underlying disease, had not received antibiotics, physical examination showed good general appearance, had no findings consistent with soft tissue, skeletal, ear, eye or umbilical infections, peripheral leukocyte count 5,000-15,000 cells/mm3 and band < 1,500 cells/mm3, normal urinalysis and stool examination if diarrhea present.

The overall incidence of bacterial infections was 47.3% (71) in 150 infants.

Of 51 infants who were identified by the Rochester criteria as low risk, only 3 (5.8%) had bacterial infection. In the group of 99 high risk infants 68 (68.7%) had bacterial infection. The spe-cificity, sensitivity and negative predictive value of the Rochester criteria for excluding all bacterial infections were 95%, 60%, 94%, respectively.
