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 - ii is an infant born at 34-2/7 weeks to a 23-year-old gravida 3, para 0 mother. prenatal screens revealed blood b positive, antibody negative, group b strep status unknown, hepatitis b surface antigen negative, rubella immune, rapid plasma reagin nonreactive. dates by 13-week ultrasound. antepartum course: antepartum course remarkable for spontaneous dichorionic-diamniotic twins. also remarkable for admission on through for shortened cervix. she was treated with betamethasone at that time and discharged to home on terbutaline. she was readmitted on through for decreased fetal movement and spontaneous decelerations, and oligohydramnios of twin a. she was admitted again on the day of delivery for uterine contractions and cervical dilatation. growth restriction (6th percentile) of twin a now appreciated. twin b in the 19th percentile. the mother with cesarean section for breech positioning of twin b. this twin emerged with tone but apnea and received brief positive pressure ventilation in the delivery room. apgar scores were 6 at 1 minute and 8 at 5 minutes. he was transported to the intensive care unit with blow-by oxygen for monitoring and treatment of prematurity. physical examination on presentation: vital signs were temperature of 96.2 rectally, heart rate 161, respiratory rate 80, blood pressure of 73/37, with a mean blood pressure of 56, oxygen saturation on room air of 85% requiring intervention, blood glucose of 53. weight was 1775 g (that is between the 10th percentile and 25th percentile). length was 44 cm (30th percentile). head circumference was 30.5 cm (25th percentile). examination was remarkable for mildly pale preterm infant in mild-to-moderate respiratory distress. he was pink, on oxygen, soft anterior fontanel, intact palate, mild-to-moderate retractions with fair air entry. a grade to 2/6 systolic murmur was present. present femoral pulses. a flat, soft, and nontender abdomen without hepatosplenomegaly. normal phallus, testes, and scrotum. stable hips. fair perfusion, slightly decreased tone and activity. hospital course by system: 1. respiratory: shortly after admission to the intensive care unit the infant was placed on continuous positive airway pressure but continued to have increased work of breathing. he was intubated and received one dose of surfactant. maximum vent settings were a peak expiratory flow of 24, with a positive end-expiratory pressure of 5, and a rate of 20, with an fio2 of 21% to 35%. he was weaned to continuous positive airway pressure on day of life two and then off of continuous positive airway pressure to room air on day of life four. he is doing well on room air with comfortable respiratory pattern. he has not had any episodes of apnea of prematurity and has not required methylxanthine therapy. 2. cardiovascular: his blood pressure has been stable throughout his hospital course. no fluid boluses or pressors have been required for blood pressure support. a murmur was noted on morning of transfer. murmur soft left mid to upper sternal border, radiating to axilla and back. murmur consistent with peripheral pulmonic stenosis. cxr with normal heart size, 4 extremity blood pressures normal, ekg with some left sided predominance but within normal limits. he remains well saturated in room air. plan to follow murmur and consider echo if clinical course/exam changes. 3. fluids/electrolytes/nutrition: upon admission to the intensive care unit intravenous fluids of d-10-w were initiated at 80 cc/kg per day. enteral feeds were initiated on day of life two, and he advanced to full volume feeds of premature enfamil at 120 cc/kg by day of life four without difficulty. plan is to continue advancment (15 cc/k ) for goal tf of 150 cc/k/day. electrolytes have been within normal limits during his hospitalization. last set of electrolytes was on with a sodium of 134, a potassium of 4.7, a chloride of 101, and a total bicarbonate of 22. his weight at the time of transfer is 1745g. 4. gastrointestinal: a bilirubin was drawn on day of life two. total bilirubin was 3.5. no phototherapy has been initiated. 5. hematology: hematocrit on admission was 41. no blood products have been given during his hospitalization. 6. infectious disease: a complete blood count with differential and blood culture was drawn upon admission to the intensive care unit. the blood culture was negative. complete blood count revealed white blood cell count of 5000, hematocrit 41, platelet count 300, with 18% polys and 0% bands. he received a 48-hour course of ampicillin and gentamicin. 7. neurology: a head ultrasound was not indicated. 8. sensory: a hearing screen has not yet been performed. 9. ophthalmology: ophthalmologic was not indicated. 10. psychosocial: social work has been involved with the family. the contact social worker can be reached at . see notes in brother's dictated summary. condition at transfer: the infant is stable in room air with a comfortable respiratory pattern, tolerating enteral feeds, and has a stable temperature in a heated isolate. discharge status: transfer to hospital. primary pediatrician: pediatrician yet to be identified. care recommendations: 1. medication: none. 2. state screening was sent at 72 hours of age, and no abnormal results have been reported. immunizations received: none. immunizations recommended: synagis respiratory syncytial virus prophylaxis should be considered from through for infants who meet any of the following three criteria: (1) born at less than 32 weeks. (2) born between 32 and 35 weeks with plans for day care during respiratory syncytial virus season, with a smoker in the household, or with preschool siblings; and/or (3) with chronic lung disease. influenza immunization should be considered annually in the fall for preterm infants with chronic lung disease once they reach six months of age. before this age, the family and other care givers should be considered for immunization against influenza to protect the infant. discharge diagnoses: 1. prematurity at 34-2/7 weeks. 2. respiratory distress syndrome. 3. rule out sepsis. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube enteral infusion of concentrated nutritional substances non-invasive mechanical ventilation diagnoses: observation for suspected infectious condition twin birth, mate liveborn, born in hospital, delivered by cesarean section respiratory distress syndrome in newborn other preterm infants, 1,750-1,999 grams stenosis of pulmonary valve, congenital malpresentation before labor affecting fetus or newborn
