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: baby boy was born on as the 1455-gram product of a 34-week twin gestation to a 32- year-old gravida 2, para 1 to 3 mother with of . prenatal laboratory studies included blood type o+, antibody negative, rpr nonreactive, rubella immune, hepatitis b surface antigen negative, and group b strep unknown. the pregnancy was notable for spontaneous monochorionic- diamniotic twin gestation and was complicated by an 18-week ultrasound showing growth discrepancy with oligohydramnios of 1 twin and polyhydramnios of the other twin, consistent with twin-twin transfusion syndrome. mother was followed closely by the maternal fetal medicine service and underwent amniotic reduction at 18 weeks and again at 26 weeks. amniotic fluid volumes appeared to equilibrate following the procedure, suggesting the possibility of an inadvertent septostomy. donor twin initially labeled as twin a in utero and subsequently found to be nonpresenting remained growth restricted underneath the 10th percentile, but did show appropriate interval growth. doppler flow studies were reassuring, and fluid has been seen in both bladders and stomachs. due to the presence of the growth restriction of the donor twin and a twin-twin transfusion syndrome, delivery was scheduled for the day of delivery at 34 weeks by c- section. mother had been given a course of betamethasone 2 weeks earlier. she was not in labor at the time of delivery and did not receive intrapartum antibiotics. at delivery, the baby was and active in the dr blow- by 02 with apgars of 8 and 9. he was transferred to the nicu. physical examination on admission: weight was 1455 grams, which is less than 10th percentile; head circumference was 29 cm, at the 10th percentile; and length was 41 cm, which is the 10th to 25th percentile. vital signs: temperature 96.5, heart rate 160s, respiratory rate 60 to 70, blood pressure 62/28 with a mean airway pressure of 41, o2 saturation was 91% with blow-by o2, 97% with cpap of 6 cm at 40% fio2. general: the baby is a growth restricted infant, active, moderate respiratory distress, more comfortable on cpap. skin: warm, pink; not pale. heent: fontanelle soft and flat. positive rr bilaterally. ears/nares normal. palate intact. neck: supple, no lesions. chest: coarse; poor aeration with positive grunting, flaring and retracting. cardiac: regular rate and rhythm. no murmur. positive femoral pulses. abdomen: soft, no hepatosplenomegaly, quiet bowel sounds, no masses, a 3-vessel cord. gu: normal male, testes descended, anus patent. extremities: hips and back normal. neuro: appropriate tone with an intact moro and grasp. hospital course by systems: 1. respiratory: the infant exhibited mild-to-moderate respiratory distress and was treated with cpap for 2 days, and quickly weaned to room air, and has been in room air since that time, and is stable. the infant did not exhibit apnea of prematurity, and no spells were noted. 2. cardiovascular: the infant remained hemodynamically stable throughout admission. no murmur has been noted. no current issues. 3. fen: the infant was initially maintained on iv fluids. enteral feeds were introduced on day of life #2 and were advanced without difficulty to full enteral feedings with a maximum caloric density of 24 calories per ounce. by the time of discharge, the infant is feeding breast milk supplemented to 26 calories with neosure, all p.o. on an ad lib basis with adequate intake and adequate weight gain. urine and stool output normal. discharge weight is 1805 grams. 4. gi: the infant had some hyperbilirubinemia and required phototherapy until day of life #10 and has been stable since. maximum bilirubin was 7.6 on day of life #5. 5. id: the infant did undergo a sepsis evaluation following delivery with an unremarkable cbc and negative blood culture. the infant received 48 hours of antibiotics, which were then discontinued. no current issues. 6. hematology: hematocrit at birth was 47 with a most recent repeat on of 45.1 with a reticulocyte count of 1.1%. he has been on iron and vitamin e. 7. neurology: the infant has maintained a normal neurologic exam throughout admission. no current issues. 8. sensory: the infant passed the hearing screen prior to discharge. condition on discharge: stable. discharge disposition: home. primary pediatrician: dr. . care and recommendations: 1. diet: breast milk supplemented with neosure to 26 calories per ounce. 2. medications: fer-in- 2 mg/kg/day. 3. state newborn screening status: initial state newborn screen was normal on and not repeated. 4. car seat position screening was performed and passed. 5. immunizations: the infant received synagis and hepatitis b vaccine on . immunizations recommended: 1. synagis rsv prophylaxis should be considered from through for infants who meet any of the following 3 criteria: (1) born at less than 32 weeks; (2) born between 32 and 35 weeks with 2 of the following: daycare during rsv season, a smoker in the household, neuromuscular disease, airway abnormalities, or school- age siblings; or (3) with chronic lung disease. 2. influenza immunization is recommended annually in the fall for all infants once they reach 6 months of age. before this age, and for the first 24 months of the child's life, immunization against influenza is recommended for household contacts and out of home caregivers. follow-up appointments scheduled: 1. ophthalmology with dr. is scheduled on . 2. the patient also has an appointment with primary pediatrician, dr. , on . 3. early intervention has been set up for the family, and there is a vna appointment on . discharge diagnoses: 1. prematurity at 34 weeks. 2. twin gestation. 3. presumed donor of twin-twin transfusion syndrome. 4. respiratory distress syndrome, resolved. 5. hyperbilirubinemia of prematurity, resolved. 6. sepsis evaluation. , md procedure: parenteral infusion of concentrated nutritional substances enteral infusion of concentrated nutritional substances non-invasive mechanical ventilation other phototherapy prophylactic administration of vaccine against other diseases umbilical vein catheterization diagnoses: need for prophylactic vaccination and inoculation against viral hepatitis observation for suspected infectious condition twin birth, mate liveborn, born in hospital, delivered by cesarean section respiratory distress syndrome in newborn neonatal jaundice associated with preterm delivery other preterm infants, 1,250-1,499 grams 33-34 completed weeks of gestation fetal blood loss "light-for-dates"without mention of fetal malnutrition, 1,250- 1,499 grams 

Answer: The patient is high likely exposed to
