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: baby #4 is a 930 gram infant born at 28 and 5/7 weeks gestational age to a 40 year old, gravida iii, para 0 mother. prenatal screens: maternal blood type 0 positive, antibody negative, gbs unknown, hepatitis b surface antigen negative; rpr nonreactive. prenatal course: notable for donor egg ivf with subsequent twinning of one embryo, resulting in quadruplet pregnancy. mother was admitted at 24 weeks gestational age for cervical shortening and treated with betamethasone. she was followed with serial monitoring. the decision was made to deliver because of progressive pre-eclampsia. delivery was by cesarean section with apgars of eight and nine. physical examination: initial physical examination was notable for a preterm infant, in moderate respiratory distress; pink color; soft anterior fontanel; normal facies; intact palate; moderate retractions; fair air entry; no murmur present; femoral pulses; flat, soft, nontender abdomen without hepatosplenomegaly. normal phallus. testes in canal. stable hips. normal perfusion. normal tone and activity for gestational age. hospital course: 1.) respiratory: initially received 3 doses of surfactant for respiratory distress syndrome and was extubated to c-pap on day of life #3. he was actually weaned to room air by day of life #7 but was returned to c-pap on day of life #10 for increased apneic and bradycardiac spells. he has been treated with caffeine for apnea of prematurity and typically has from three to ten apneic or bradycardiac episodes daily. in the latter part of , had significantly increased nasal and tracheal secretions, associated with an increase of apnea and bradycardia episodes, up to 12 to 17 per day. viral ifa and cultures were sent with negative results. has not required reintubation for these spells, which appear to be improving at the time of this dictation. 2.) cardiovascular: was initially diagnosed clinically in the first three days of life with patent ductus arteriosus and received a single course of indomethacin with resolution of murmur and widened pulse pressures. he has not had any other active cardiovascular issues. 3.) fluids, electrolytes and nutrition: birth weight was 930 grams. initially received parenteral nutrition. he was started on enteral feeds on day of life #4 which were advanced without difficulty to his total enteral intake of 130 cc per kg per day of premature enfamil 30 kilocalories per ounce/mother's milk 30 kilocalories per ounce, all gavage. he had been on 150 cc per kilo per day but was decreased to 130 on day of life #24 for some mild dependent edema. he has continued to gain weight on the lower volumes with weight at the time of this dictation of 1,365 grams. 4.) gastrointestinal: was treated with phototherapy for hyperbilirubinemia from day of life #2 until day of life #14 with peak bilirubin on day of life #3 of 6.6 and most recent bilirubin of 2.2 on . has had some mild problems with , not requiring reglan or zantac. 5.) hematology: blood type is a negative, direct antibody test negative. during the time when had increased apnea and bradycardia episodes, a hematocrit was checked on and he was transfused with 20 cc per kilo of packed red blood cells for a hematocrit of 31 and reticulocyte count of 3.6%. he has not had a more recent hematocrit. 6.) infectious disease: was treated with ampicillin and gentamycin in the first two days of life for a 48 hour sepsis evaluation with negative blood cultures. he had another sepsis evaluation performed on for increased apnea and bradycardia episodes. at that time, his white blood cell count was 24 with 56% polys, 6% bands, hematocrit of 31; platelets of 850. blood cultures drawn at that time were negative. nasopharynx aspirates were sent for viral ifa and cultures and were negative. he was treated initially with ampicillin and gentamycin with oxacillin added after one day because of a sibling with staphylococcal scalded skin syndrome. antibiotics were discontinued on after blood cultures remained negative. he has no other infectious disease issues. 7.) neurology: a head ultrasound performed on day of life #7 () was negative. he is due for a routine repeat one month head ultrasound. 8.) sensory: has not yet received his hearing test. he is due for his first ophthalmologic examination within the next few days. 9.) routine health care maintenance: his initial state newborn screen on has a low thyroxin level. a repeat newborn screen sent on was completely normal. has not yet received his first hepatitis b immunization which is due at one month of age. condition: stable. a primary pediatrician has not yet been chosen. discharge diagnoses: prematurity at 28 and 5/7 weeks gestational age. status post patent ductus arteriosus treated with one course of indocin. status post respiratory distress syndrome, treated with surfactant. status post hyperbilirubinemia. apnea of prematurity. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified parenteral infusion of concentrated nutritional substances insertion of endotracheal tube other phototherapy prophylactic administration of vaccine against other diseases transfusion of packed cells diagnoses: need for prophylactic vaccination and inoculation against viral hepatitis observation for suspected infectious condition extreme immaturity, 750-999 grams respiratory distress syndrome in newborn neonatal jaundice associated with preterm delivery 27-28 completed weeks of gestation patent ductus arteriosus retrolental fibroplasia other multiple birth (three or more), mates all liveborn, born in hospital, delivered by cesarean section 

Answer: The patient is high likely exposed to
