A study performed at Strong Memorial Hospital in Rochester, New York, showed that infants ≤ 60 days old meeting the following criteria were at low-risk for having a serious bacterial illness: * generally well-appearing * previously healthy * full term (at ≥37 weeks gestation) * no antibiotics perinatally * no unexplained hyperbilirubinemia that required treatment * no antibiotics since discharge * no hospitalizations * no chronic illness * discharged at the same time or before the mother * no evidence of skin, soft tissue, bone, joint, or ear infection * White blood cells (WBCs) count 5,000-15,000/mm3 * absolute band count ≤ 1,500/mm3 * urine WBC count ≤ 10 per high power field (hpf) * stool WBC count ≤ 5 per high power field (hpf) only in infants with diarrhea Those meeting these criteria likely do not require a lumbar puncture, and are felt to be safe for discharge home without antibiotic treatment, or with a single dose of intramuscular antibiotics, but will still require close outpatient follow-up. One risk for Group B streptococcal infection (GBS) is preterm rupture of membranes. Screening women for GBS (via vaginal and rectal swabbing) and treating culture positive women with intrapartum chemoprophylaxis is reducing the number of<unk>  caused by GBS. Abnormal heart rate characteristics (HRC) of transient decelerations and reduced baseline variability in heart rate are a risk factor for impending<unk> .
