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 is a 2,330 gm boy born at 31-4/7 week's gestational age to a 22-year-old g4, p1 mother with estimated date of delivery . the pregnancy was complicated by polyhydramnios of unknown etiology with an afi of 27 and unstoppable preterm labor. the mother presented with premature cervical dilation. she was transferred from for further medical care. prenatal screens were notable for: maternal blood type o+, antibody negative, rpr nonreactive, hepatitis b surface antigen unknown and not sent prenatally, rubella immune, gbs unknown. artificial rupture of membranes 2 hours prior to delivery and antibiotics for multiple doses prior to delivery. the mom initially received 1 dose of betamethasone and magnesium. the infant was born by unstoppable vaginal delivery with apgar scores of 7 at 1 minute and 8 at 5 minutes. he was noted to have decreased tone at delivery. initial physical exam: weight 2,330 gm (greater than 90th percentile), length 45 cm (75th-90th percentile), head circumference 32.5 cm (greater than 90th percentile). temperature 99.8, heart rate 120-137, respiratory rate 44, saturating 100% in room air, blood pressure 77/42 with mean arterial pressure of 52, initial d-stix 29. he was active and alert, but with mildly decreased tone. there was a bruise noted on his forehead. pupils were reactive bilaterally with red reflex present bilaterally. palate was intact. lungs were clear bilaterally with shallow air movement, and mild intercostal retractions, and intermittent grunting. the heart rate and rhythm were regular with no murmur and 2+ femoral pulses bilaterally. the abdomen was soft with hypoactive bowel sounds with no masses or distention. hips were stable. midline spine with no sacral dimple or hair . normal male external genitalia with testes both high in the canal. the anus was patent. gag and suck reflexes were present. summary of hospital course by systems - 1) respiratory: decreased air movement and grunting initially. chest x-ray was negative for any focal abnormalities. he was started on cpap of 6 and 21% oxygen, but was weaned to nasal cannula by one day of age, and to room air by two days of age. subsequently, he maintained saturations in the high-90s in room air without any respiratory distress. he has not shown significant apnea of prematurity with generally 0-2 apneic or bradycardic spells per day. he has not been started on caffeine. 2) cardiovascular: has remained cardiovascularly stable throughout his admission with normal blood pressures and no murmur. no active issues. 3) fluid, electrolytes and nutrition: his initial d-stix was 29, and he received a total of 4 cc/kg of d10w. he was continued on iv fluids and was initially npo, but started on enteral feeds pg when his respiratory distress was resolved. he has advanced without problem on his enteral feeds, and is currently receiving 150 cc/kg/d of premature enfamil supplemented to 24 cal/oz, all pg. he has occasional spits, so the feeds are run over 2 hours. he has had no subsequent problems with hypoglycemia after that first day of life. his weight at transfer was 2,215 gm, still below birth weight of 2,330 gm. 4) gi: phototherapy was initiated on (3 days of age) for a bilirubin of 13.6. phototherapy was discontinued on the 21rst with a bilirubin of 4.6, and a rebound bilirubin on was 5.3. with this mild rate of rise, we followed his jaundice clinically. he is not significantly jaundiced at this time, and no further bilirubin measurements have been taken. maternal blood type was o+, antibody negative, and baby blood type was also o+, direct antibody negative. 5) infectious disease: because of his preterm birth and initial respiratory distress, was started on a sepsis evaluation upon admission. his initial cbc showed a white blood cell count of 9.6 with 30% polys and 0% bands, hematocrit 47, platelets 224. ampicillin and gentamicin were given until blood cultures were negative for 48 hours. because maternal hepatitis b status was not known, received the hepatitis b immunization on admission on . the mother had a hepatitis b study sent on admission here, but was inadvertently sent as the hepatitis b e antigen on which was negative. however, because hepatitis b e antigen is was not sensitive as hepatitis b s antigen, so hepatitis b immune globulin was given to on after consent was obtained. has no active infectious disease issues. 6) neurology: because of gestational age, a routine head ultrasound was performed on which showed no abnormalities. 7) sensory: hearing screening has not yet been performed. ophthalmology exam has also not yet been performed. condition at discharge/transfer: stable. discharge disposition: special care nursery, phone number (. primary pediatrician: dr. in , phone number (. care/recommendations: 1. feeds at discharge are premature enfamil supplemented to 24 cal at 150 cc/kg/d given over 2 h for a history of spits. 2. no medications. 3. car seat position screening has not yet been done. 4. state newborn screen was sent on with results pending. 5. hepatitis b immunization given on , and hepatitis b immune globulin given on . 6. synagis rsv prophylaxis should be considered from through for infants who meet any of the following 3 criteria: 1) born at less than 32 week's; 2) born between 32 and 35 week's with 2 of 3 of the following: daycare during rsv season, smoker in the household, neuromuscular disease, airway abnormalities, or school-aged siblings; or 3) with chronic lung disease. 7. the parents request that receive a circumcision when he is older. discharge diagnoses: 1. prematurity at 31-4/7 week's gestational age. 2. status post hyperbilirubinemia. 3. unknown maternal hepatitis b status. 4. feeding immaturity. , m.d. dictated by: medquist36 procedure: parenteral infusion of concentrated nutritional substances non-invasive mechanical ventilation other phototherapy prophylactic administration of vaccine against other diseases diagnoses: need for prophylactic vaccination and inoculation against viral hepatitis observation for suspected infectious condition single liveborn, born in hospital, delivered without mention of cesarean section neonatal jaundice associated with preterm delivery other preterm infants, 2,000-2,499 grams 31-32 completed weeks of gestation transitory tachypnea of newborn other noxious influences affecting fetus or newborn via placenta or breast milk 

Answer: The patient is high likely exposed to
