Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: this is the second admission for this former full term infant readmitted on day of life number four. he was the product of a term gestation pregnancy born to a 36 year-old g3 p1 to 2 woman. prenatal screens, type a positive, antibody negative, rubella immune, hepatitis b surface antigen negative, rpr nonreactive, group beta strep status positive. the mother received antibiotics in labor. uncomplicated spontaneous vaginal delivery with apgars of 9 at one minute and 9 at five minutes. birth weight was 3.965 kilograms. the infant had an uneventful postnatal course and was discharged home on day of life number two. the first evening after discharge the parents report the infant as fussy and then becoming increasingly sleepy and lethargic. he continued to feed well with wet diapers and stooling. he was taken to the pediatrician's office on the day of admission due to his jaundiced coloring. he was sent to the for a bilirubin level, which was 23 mg per deciliter. he was admitted to the neonatal intensive care unit for management of unconjugated hyperbilirubinemia. physical examination on admission to neonatal intensive care unit: weight 3.905 kilograms. temperature 97.9. heart rate 130. respiratory rate 46. pressure 74/43. oxygen saturation was 87% in room air. slightly tachypneic. clear chest. heart regular with soft vibratory murmur heard over the left mid sternal border. +2 femoral pulses. abdomen soft without masses. testes descended bilaterally. normal phallus. patent anus. straight spine. neurological appropriate tone and reflexes. hospital course/laboratory data: 1. respiratory: with the low oxygen saturation noted upon admission the infant was placed on nasal cannula o2. he required 100 cc per minute flow. the oxygen requirement resolved within twelve hours after admission and the baby remained in room air through the remainder of admission. o2 saturations at the time of discharge were greater then or equal to 96%. chest x-ray was within normal limits. 2. cardiovascular: the murmur noted upon admission persisted and remains present at the time of discharge. 3. fluids, electrolytes and nutrition: the infant continued to feed well. a supplemental intravenous line was started for additional hydration for treatment of the hyperbilirubinemia. serum electrolytes at the time of admission had a sodium of 138, potassium 4.7, chloride 101, total carbon dioxide of 28. the discharge weight is 3.845 kilograms. 4. infectious disease: due to the reports of lethargy and the oxygen desaturation, this infant was evaluated for sepsis. a white cell count was 13,000 with a differential of 43% polys, 1% bands. platelets were 227,000. a culture and lumbar puncture were obtained prior to initiating antibiotics. the culture was no growth at 48 hours. the lumbar puncture had a cell count with 4 red cells and 1 white cells per cubic centimeter. normal glucose and protein. the cerebral spinal fluid culture was also negative at 48 hours and the antibiotics were discontinued. 5. hematological: hematocrit at admission was 39.9%. a reticulocyte count was 7.6%. the baby is type a positive, negative. 6. gastrointestinal: the infant was treated with intensive phototherapy. a repeat bilirubin within 4 hours of admission was 22.2 total over 0.5 direct mg per deciliter. a repeat serum bilirubin twelve hours later was a total of 15.4 over 0.4 direct. a subsequent bilirubin was 10 mg per deciliter and the phototherapy was discontinued. a rebound bilirubin performed in the morning of was 12.2 mg per deciliter. 7. sensory: repeat hearing screen was performed and passed. condition at discharge: good. discharge disposition: home with parents. the primary pediatrician is dr. , pediatric associates, , . phone . fax . care and recommendations on discharge: po ad lib feeding. no medications. no further immunizations administered. follow up appointments recommended: return to the on for a bilirubin check. discharge diagnoses: 1. unconjugated hyperbilirubemia. 2. suspicion for sepsis ruled out. , m.d. dictated by: medquist36 procedure: spinal tap incision of lung ultraviolet light therapy diagnoses: observation for suspected infectious condition unspecified fetal and neonatal jaundice 

Answer: The patient is high likely exposed to
