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: briefly, this is a 27 week twin number one boy with a birth weight of 1365 that was delivered to a 29 year-old gravida 3 para mother with unremarkable prenatal screens. the mother was originally admitted to , but was transferred to the on the day of delivery secondary to bed shortage. hospital course: the baby was initially intubated with a diagnosis of surfactant deficiency. he received three doses of surfactant with some improvement. of note, earlier in his hospital course he was noted to have episodes of red secretions from the endotracheal tube that resolved. these episodes were short lived, mild and was not considered to be evidence of a pulmonary hemorrhage. he had remained intubated weaning slowly on his settings and was actually extubated to cpap during the late part of . he remained intubated with for most of the first few weeks of life and made slow improvement on his ventilatory requirements. he was transitioned to cpap at at day of life 31 successfully. his fio2 requirements at the time remained at about 22 to 40% with some mild retractions noted. however,he appeared comfortably and was attempted on nasal cannula shortly thereafter. his oxygen flow slowly started to escalate to 400 cc during that time and because of due to increased work of breathing he was put back on mp-cpap on at day of life 41. this resulted in a satisfactory decrease in apnea and bradycardia episode. he has been maximized on caffeine as well. he remained stable with decreasing oxygen requirements to about 21 to 30% on cpap and eventually was weaned to room air cpap of 5. he was again trialed on nasal cannula at 200 cc flow on day of life 47 and has remained stable since. he does have occasional drifts and periodic breathing that resolves with mild stimulation and suctioning. at day of life 51 he was tried off caffeine and has remained stable with minimal spells since. from a cardiovascular standpoint, briefly the baby had been treated with one course of indomethacin for a clinically evident pda. subsequent echocardiogram showed no evidence of a persistent patent ductus arteriosus and good biventricular function. it is also noted that initially the patient had a transient hypotension in the first few days of life with dopamine requirements. he was off of dopamine by day of life four. fluids, electrolytes and nutrition, fluids were initially due to indomethacin dopamine requirements the baby was kept npo on parenteral nutrition. feedings were started on day of life 6 and was advanced by 10 cc b.i.d. over the course of the next few weeks. he has also been on supplemental vitamin e and iron. he has occasional spits with feeds that require the feeds to be given over an hour to an hour and forty five minutes. that is also slowly resolving. currently he is total fluids at 140 cc per kilo per day on pe-26 without promod. he is showing nice weight gain and growth. on the day of this dictation his formula was changed to pe-24 and we will be following his weight gain closely. hematology, the patient was briefly on phototherapy due to prolonged hyperbilirubinemia. he has also tolerated a few blood transfusions during his early hospital course without any complications. infectious disease, the baby was initially treated with ampicillin and gentamicin for 48 hours. his initial cbc was unremarkable for sepsis. it is of note, however, that his platelet count was initially 143,000. he did receive a sepsis evaluation on day of life 13 secondary to temperature instability. this evaluation was unremarkable (including an lp). he did receive 48 hours of vancomycin and gentamicin. acyclovir was started, but was discontinued when the pcr/hsv results were negative. neurology, the infant has had head ultrasounds, which showed no evidence of intraventricular hemorrhage. this was a head ultrasound within the first week of life as well as a head ultrasound at 30 days of age. psycho/social, primary pediatrician is dr. at hospital. we have had multiple meetings with the parents. both mom and dad are actively involved in the infant's care and would like to be updated on a regular basis. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more spinal tap incision of lung insertion of endotracheal tube enteral infusion of concentrated nutritional substances diagnoses: single liveborn, born in hospital, delivered by cesarean section observation for suspected infectious condition chronic respiratory disease arising in the perinatal period patent ductus arteriosus unspecified fetal and neonatal jaundice pulmonary congestion and hypostasis umbilical hernia without mention of obstruction or gangrene extreme immaturity, 1,250-1,499 grams 

Answer: The patient is high likely exposed to
