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: this interim summary covers the dates of , through . baby is a now 20-day-old ex-33-3/7 week 2.105 kilogram baby who was born to a 33-year-old g3, p2, mom via cesarean section. mom's prenatal screens include b positive, rubella immune, rpr nonreactive, hepatitis b surface antigen positive and unknown gbs status. her pregnancy was unremarkable until preterm labor. mom had had prior cesarean section and, therefore, had repeat surgery. there was no maternal fever documented and as such mom did not receive antibiotic prior to delivery. cesarean section notable for slightly difficult extraction of shoulder in the dr. fluid was also noted to be bloody at the time of delivery with question of malabruption. resuscitation unremarkable with spontaneous cry. apgars were 8 and 8 at one and five minutes respectively. physical examination: 98.3, 150, 50's, blood pressure 56/38. accu-chek 73. birth weight 2105 grams. head circumference 31 cm. length 45 cm. heent: facial bruising, nondysmorphic, no cleft lip or palate. cardiovascular: regular rate and rhythm, no murmur. pulses equal. lungs: occasional grunting. air exchange adequate bilaterally. abdomen soft, non-tender, no masses palpable. liver 1 cm below costal margin. genitourinary: normal external male genitalia with testes descended bilaterally. neuro: normal tone. moro present and equal. suck present. summary of hospital course by systems: 1. respiratory: patient originally had mild respiratory distress requiring cpap for approximately 24 hours. after that time he was easily weaned to room air and has not had additional issues from a respiratory standpoint. this includes an absent apnea or bradycardias. however, of recent (in the last 24 hours) patient was noted to have some duskiness with feed. he had originally been taken off of oximetry but this has been resumed to further follow symptoms. 2. cardiovascular: has remained stable from a cardiovascular standpoint without concerns of murmur. 3. fluids, electrolytes and nutrition: patient originally was supported on total parenteral nutrition with gradual advancement of feeds. he originally started gastric feeds on day of life four. feeds were gradually advanced with achievement of full feeds on day of life eight. we have currently been feeding with breast milk 24 kcals, both p.o. and p.g. however, at this point he takes only about 50% of his feeds orally. has been demonstrating good weight gain on this feeding regimen with most recent weight on day of life 20 () of 2.43 kilograms. 4. gastrointestinal: as briefly mentioned above, there have been some concerns for dusky spells with feeding in the past 24 hours. however, nobody has ever described that chokes, gags or sputters with feeds. from a bilirubin standpoint, had a prolonged course of hyperbilirubinemia with phototherapy originally initiated on day of life two. peak bilirubin was reached on day of life five at 14.0. he gradually declined but ultimately required phototherapy through day of life ten. a rebound bilirubin on day of life 12 was 11.0. at time of dictation patient still appears moderately jaundiced. . with his prolonged course of hyperbilirubinemia, a repeat bilirubin will be obtained tomorrow morning. 5. infectious disease: had a 48 hour rule out sepsis with ampicillin and gentamicin. blood culture remained negative for this period of time. is known to be hepatitis b surface antigen positive. for this reason he was given both a hepatitis b vaccine as well as hbig after delivery. no additional issues from an infectious disease standpoint. 6. neurology: the patient does not meet criteria for screening head ultrasound. 7. sensory: patient will still need hearing screen prior to discharge. he does not fit criteria for ophthalmology examination. primary pediatrician: health center, , m.d. care/recommendations: a. feeds at interim: breast milk 24 kcal at 150 cc/kg/day p.o. or p.g. b. medications: none. c. car seat positioning: pending. d. state newborn screen: sent. e. immunizations received: hepatitis b on day of life zero (). interim diagnoses: 1. prematurity at 33-3/7 weeks. 2. respiratory distress, resolved. 3. rule out sepsis, resolved. 4. maternal hepatitis b infection. dr.,, 50-470 dictated by: medquist36 procedure: non-invasive mechanical ventilation other phototherapy diagnoses: single liveborn, born in hospital, delivered by cesarean section observation for suspected infectious condition respiratory distress syndrome in newborn neonatal jaundice associated with preterm delivery other preterm infants, 2,000-2,499 grams 33-34 completed weeks of gestation 

Answer: The patient is high likely exposed to
