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: the infant was admitted for sepsis evaluation. during the evaluation, 1 episode of desaturation was noted and the infant was placed on nasal cannula. the infant is a full term, 4435 gram female newborn who was born to a 19-year-old, gravida 1, para 0 now 1 mother. prenatal screens: o+, antibody negative, hepatitis b negative, rpr nonreactive, rubella immune, gbs positive, hiv negative. pregnancy reported benign. sepsis risk factors reviewed. mother is gbs positive. maternal t-max of 102.8. ruptured membranes x9 hours with clear fluid. intrapartum antibiotics greater than 4 hours prior to delivery and fetal tachycardia. maternal anesthesia by epidural. delivered by cesarean section for nonreassuring fetal heart rate tracing. required positive pressure ventilation at delivery. apgars 3 and 7. physical examination at discharge: current weight 4330 grams, greater than 90th percentile, length 53 cm, greater than 90th percentile, and head circumference 36 cm, greater than 90th percentile. vital signs per careview. lga female infant. respiratory: the infant remains on room air. breath sounds are equal and clear. no retractions. respiratory rate are 30 to 60. cardiac: no audible murmur on exam, regular rate and rhythm. pulses are palpable and equal. capillary refill less than 3 seconds. mucous membranes are pink and moist. skin is intact, no lesions, rashes or bruises on exam. mongolian spot on buttocks. gi: abdomen soft and round, positive bowel sounds, no hepatosplenomegaly on exam. no palpable masses on exam. patent anus. gu: normal female genitalia. neuro: anterior fontanels open and soft. infant alert, awake and active, good tone. no sacral dimple on exam. summary of hospital course by systems: respiratory: infant initially placed on nasal cannula o2 at 200 cc with an fio2 of 50% on admission. in nicu, weaned to room air on day of life #2. the infant currently remains on room air. cardiovascular: no concerns at this time. no murmur at this time. fluid and electrolytes nutrition: the infant initially fed in l&d for a d stick of 34. infant made npo upon admission to nicu. total fluids were at 60 per kilo per day of d10w with daily d sticks. follow intraoral feeds ad lib with similac 20 cal on day of life #1. gi: no clinical signs of jaundice. bilirubin on day of life #3 was 5.6/0.4. the infant does not require phototherapy at this time. hematology: blood type not identified. current hematocrit on admission was 61.6 with a platelet count of 145,000. repeat on day of life #2, hematocrit 58 with a platelet count of 130,000. repeat platelet count on day of life # 142. id: blood culture with cbc with differential on admission to the nicu results: white count 11.3, 52 polys, 3 bands with 362 nucleated red blood cells. repeat cbc on day following life #2 results: wbc 15.3, 57 polys, 0 bands and 85 nucleated red blood cells. lumbar puncture performed on admission due to clinical status for sepsis, results normal. csf culture negative to date. blood culture is also negative to date. the infant will be treated with ampicillin and gentamicin for a total of 7 days for presumed sepsis. gentamicin levels done on day of life #3: gentamycin trough was 1.4 and gentamycin peak is pending. neurologic: the infant does not meet criteria for head ultrasound. recommend hearing screen prior to discharge. condition on transfer to newborn nursery: stable. discharge disposition: to newborn nursery. name of pediatrician not yet identified. care and recommendations: feeds: similac 20 calories ad lib. medication: gentamicin 18 mg q.24 h., ampicillin 500 mg iv q.12 h. for a total of 7 days. newborn screening sent per protocol: results are pending. dr 50.aef dictated by: medquist36 d: 02:30:14 t: 08:12:17 job#: procedure: spinal tap incision of lung prophylactic administration of vaccine against other diseases diagnoses: single liveborn, born in hospital, delivered by cesarean section need for prophylactic vaccination and inoculation against viral hepatitis observation for suspected infectious condition other "heavy-for-dates" infants other respiratory problems after birth neonatal tachycardia 

Answer: The patient is high likely exposed to
