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 is a full term, 4250 gram male infant born on , to a 36 year old gravida iii, para ii, mother. prenatal screens were remarkable for blood type o positive, antibody unknown, rubella immune, rpr nonreactive, hepatitis b surface antigen negative, and gbs negative. there was a maternal history of depression for which mother was on zoloft. mother has had one previous child who is healthy and had no issues of thrombocytopenia. this pregnancy was reportedly uncomplicated. neonatal intensive care unit was called to assess the patient when the infant was noted to have bruising on the thorax and was subsequently found to be thrombocytopenic. mother's platelet count was normal at 274,000. there were no prenatal risk factors. mother was gbs negative. there was no maternal fever and rupture of membranes was less than 24 hours. maternal anesthesia was via epidural/spinal. the infant was delivered by repeat cesarean section with apgar of eight and nine. neonatal nurse practitioner was asked to see the infant in the newborn nursery for petechiae and bruising. a complete blood count was drawn at that time, and platelet count was reported at 5000. a repeat level was sent and returned at 8000. at that point, the infant was transferred to the neonatal intensive care unit for further management. physical examination: on admission, weight is 4250 grams (lga). in general, a comfortable appearing newborn in no acute distress, nondysmorphic. anterior fontanelle open and flat. red reflex times two. positive suck. normally placed ears. intact clavicles with supple neck. lungs were clear to auscultation bilaterally and equal. examination of the heart revealed regular rate and rhythm with no murmurs. there were normal femoral pulses. the abdomen was soft with bowel sounds. examination of genitourinary revealed normal male phallus with testes descended bilaterally. patent anus. there were no sacral abnormalities noted. the hips were stable. the infant was pink and well perfused with some acrocyanosis. examination of the skin revealed diffuse petechiae over the trunk, abdomen and groin areas of the extremities. the face and back were relatively spared. there was also some larger bruising over the chest and groin. no joint swelling or effusions. neurologic examination revealed a normal alert infant and effective tone and strength. hospital course: respiratory - the patient was stable in room air throughout his admission. cardiovascular - the patient was hemodynamically stable throughout his admission in the neonatal intensive care unit. fluids, electrolytes and nutrition - the patient was allowed to breast feed and bottle feed similac 20 with good p.o. intake during his admission. hematology - initial platelet count of 5,000 with follow-up of 8,000. the remainder of the complete blood count was unremarkable with a white blood cell count of 11.4 and hematocrit of 48.1. the patient was transfused with 15 cc/kg of platelets. platelet count one hour after transfusion was 145,000. platelet count four hours after transfusion was 139,000 and approximately ten hours after transfusion, the platelet count remained stable at 138,000. maternal platelet count as reported earlier was normal. maternal laboratories have been sent including a pla-1 antibody. infectious disease - given the thrombocytopenia, complete blood count and blood culture were obtained as well as the baby being started on ampicillin and gentamicin. blood cultures are no growth to date. the baby remains on ampicillin and gentamicin for a full 48 hour rule out. neurology - given the initial platelet count of 5,000, a head ultrasound was performed on , which was reported as within normal limits. condition on discharge: good. disposition: to normal newborn nursery. primary care pediatrician: dr. , in . care/recommendations: 1. continue p.o. ad lib feedings. 2. continue ampicillin and gentamicin for full 48 hour rule out. 3. repeat platelet count in a.m. to assure that platelet count has stabilized and follow-up on maternal laboratories sent. discharge diagnoses: 1. thrombocytopenia, likely alloimmune. 2. rule out sepsis. , dictated by: medquist36 d: 15:45:44 t: 18:12:40 job#: procedure: transfusion of platelets diagnoses: single liveborn, born in hospital, delivered by cesarean section observation for suspected infectious condition other "heavy-for-dates" infants transient neonatal thrombocytopenia 

Answer: The patient is high likely exposed to
