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: this is an 800 gram 25 1/7 weeks (estimated date of delivery ) twin #1 male born to a 39 year-old gravida iii, para 0, now ii, sab i, tab i white female. prenatal screens revealed blood type ab negative, antibody negative, rpr nonreactive, rubella immune, hepatitis b surface antigen negative, group b strep unknown. the mother's past medical history is remarkable for a cone biopsy and ulcerative colitis this pregnancy was by in utero insemination. ultrasound revealed normal anatomy. amniocentesis was declined. pregnancy was complicated by cervical shortening with rescue cerclage at 22 weeks and then premature labor at 24 4/7 weeks (). she was initially managed at with magnesium sulfate, dexamethasone and ampicillin. she was transferred to for further management. she continued to be tocolyzed with magnesium sulfate and then indocin times 48 hours secondary to shortness of breath on magnesium. dexamethasone course was complete. she continued on ampicillin. she required reinstitution of magnesium sulfate secondary to recurrence of labor. this morning she had increasing contractions and on examination was 7 cm dilated. the cerclage was removed. rupture of membranes occurred at delivery. she progressed to vaginal delivery under epidural anesthesia. the infant was vigorous. he received blow-by oxygen. he was electively intubated. apgars were 8 at one minute and 8 at five minutes. he was transferred to the neonatal intensive care unit for further management. physical examination: revealed a premature intubated male. his eyes are fused. temperature 97.2, pulse 150, respiratory rate 54, blood pressure 40/25 with a mean of 30 and then 49/26 with a mean of 35. oxygen saturation was 100%. weight 800 grams, length 34 cm, head circumference 24 cm. anterior fontanelle is soft and flat. he is not dysmorphic. his eyes are fused. he is orally intubated, has good aeration and crackly breath sounds, status post survanta. there is no murmur. he has a soft abdomen. there is no hepatosplenomegaly. umbilical lines are in place. he has normal male genitalia for age. testes are undescended. his anus is patent. there is no sacral dimple. he has normal tone for age. course in neonatal intensive care unit: is remarkable for: 1. respiratory. he had respiratory distress syndrome and was given one dose os surfactant at 6 a.m. venous blood gas on ventilatory settings of 37 percent, pressures 23/5, rate 20 revealed ph 7.23, pco2 64, po2 54. cxr was consistent with moderate rds. 2. cardiovascular: he has remained hemodynamically stable. 3. fluid/electrolytes, nutrition: he is npo on d10w at 80 g/d. his ds has ds have bb3. gastle. 4. hematologic: he had a hematocrit of 47.3, platelet count of 279. 5. infectious disease: cbc was sent and revealed a white blood cell count of 9.5, differential is pending at time of dictation. blood culture was sent. he was placed on ampicillin and gentamicin. the dose of ampicillin was given before transfer. the dose of gentamicin is to be given. 6. neurology: there are no current issues. he will be due for head ultrasound at approximately one week of age. 7. sensory: he will require ophthalmologic and hearing screenings at the appropriate times. 8. other: vitamin k was given. he received no erythromycin since his eyes are fused. pku state laboratory screen was sent. umbilical artery and umbilical venous lines were placed by n.n.p. buck. babygram shows the umbilical artery and umbilical venous lines to be low and they are being adjusted. condition at discharge: stable. discharge disposition: the infant is being transferred to neonatal intensive care unit secondary to a shortage of beds due to high census in our neonatal intensive care unit. pediatrician is not known at present. care recommendations: the infant is on mechanical ventilation. he has received one of surfactant. he can receive up to four doses of survanta depending on his respiratory status. he is being maintained n.p.o. with intravenous fluids of d10w at 80 cc per kilogram per day. he will require close monitoring of his blood pressure with volume and/or dopamine as needed if he becomes hypotensive. he will also need monitoring for early treatment of a patent ductus arteriosus. he is on ampicillin and gentamicin for rule out sepsis with the course dependent on laboratory data and clinical course. he will need to have a head ultrasound by day 7. the parents have been completely updated and are aware of the need for transfer to . this was a maternal transfer from and when the babies are ready for level two care there is the possibility for transfer there. discharge diagnosis: 1. prematurity. 2. twin #1. 3. respiratory distress syndrome, status post survanta times one. 4. rule out sepsis on antibiotics. , m.d. dictated by: medquist36 d: 08:52 t: 08:55 job#: procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube diagnoses: extreme immaturity, 750-999 grams respiratory distress syndrome in newborn twin birth, mate liveborn, born in hospital, delivered without mention of cesarean

Answer: The patient is high likely exposed to
