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 boy is a 1680-gram 30 and week infant born to was 29-year-old gravida 2, para 1 (now 2) mother with prenatal screens as follows: o positive, antibody negative, rapid plasma reagin nonreactive, rubella immune, hepatitis b surface antigen negative, and group b strep status unknown. the pregnancy was complicated by preterm labor treated with magnesium sulfate and betamethasone. she was treated with ampicillin as well. biophysical profile was with an estimated fetal weight of grams. rupture of membranes were one hour prior to delivery. this was a breech presentation, and the infant was delivered by cesarean section under a combined spinal epidural anesthesia. the infant was vigorous at birth with apgar scores were 8 at one minute and 8 at five minutes. the infant was admitted to the neonatal intensive care unit on blow-by oxygen for prematurity. mother's history was remarkable for hypothyroidism being treated with levoxyl. previous obstetric history was remarkable for a 31 and week infant born at who was doing well. physical examination on presentation: birth weight was 1680 grams (75th percentile), head circumference was 29.25 cm (50th percentile), and length was 40.5 cm (50th percentile). anterior fontanel was soft, flat, and nondysmorphic. intact palate. clear breath sounds. no distress. no murmurs. normal pulses. the abdomen was soft. a 3-vessel cord. no hepatosplenomegaly. normal male genitalia with left testicle in the scrotum. the right testicle high in the canal. the anus was patent. no hip click. no sacral dimple. normal tone and activity for age. initial dipstick was 38. the infant was given one d-10-w bolus. hospital course by issue/system: 1. respiratory issues: the infant was initially placed on continuous positive airway pressure, and he weaned to room air on day of life two and has been doing well on room air since. he had apnea of prematurity and was started on caffeine on day of life four with improvement. his last bradycardia episode occurred on day of life eleven after his caffeine had been discontinued on day of life nine. he continued to be monitored for further apneic and bradycardic episodes. 2. cardiovascular system: the infant has been hemodynamically stable throughout his admission. no murmurs were appreciated. 3. fluids/electrolytes/nutrition issues: the infant was started on enteral feeds on day of life two with improvement of respiratory distress, and he was slowly advanced on his volume and calories. he is currently taking total fluids of 840 cc/kg per day of breast milk 26. his birth weight was 1680 grams, and his weight at the time of this dictation (on day of life eleven) was 1670 grams. he has been noted to have some spits with his feeding, and that is why his total fluids are 840 cc/kg per day. 4. gastrointestinal issues: the infant's bilirubin level peaked on day of life three at 9.1; at which time phototherapy was started. phototherapy was discontinued on day of life five, and a rebound bilirubin on day of life six was 6.4. 5. infectious disease issues: the infant was started on ampicillin and gentamicin for a sepsis rule out. his blood cultures remained no growth to date at 48 hours; at which time his antibiotics were discontinued. 6. neurologic issues: the infant had a screening head ultrasound on day of life seven which revealed no intraventricular hemorrhage but two small choroid plexus cysts on the right. he was to have another screening head ultrasound on day of life thirty. 7. hematologic issues: the infant did not require any transfusions during this admission. 8. sensory issues: hearing screening will be performed prior to discharge. 9. ophthalmologic issues: eyes have not been examined at this time, and he was due for his first examination at 32 weeks to 33 weeks corrected gestational age. condition: condition at the time of this dictation revealed the infant had been doing well on room air and continued to have mild apnea of prematurity; now off caffeine. he was tolerating his feeds well and gaining weight. primary pediatrician: name of primary pediatrician is dr. of . medications on discharge: current medications included iron. regular health care maintenance: 1. car seat position screening will be performed prior to discharge. 2. state newborn screening has been sent. 3. the infant has not received any immunizations during this interim period. discharge diagnoses: 1. prematurity at 30 and 5/7 weeks. 2. respiratory distress syndrome. 3. apnea of prematurity. , m.d. dictated by: medquist36 d: 13:59 t: 15:25 job#: procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours 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 circumcision audiological evaluation other oxygen enrichment diagnoses: single liveborn, born in hospital, delivered by cesarean section neonatal jaundice associated with preterm delivery primary apnea of newborn neonatal bradycardia other respiratory problems after birth ventricular septal defect other preterm infants, 1,500-1,749 grams 

Answer: The patient is high likely exposed to
