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 is an interim dictation summary covering the dates between and . briefly, this is a former 33 week twin male infant with a birth weight of 2.315kg who is now 18 days old. his corrected gestational age is 35 5/7 weeks. please refer to previous summary for details of earlier course, which is notable for respiratory distress syndrome requiring intubation and surfactant therapy, polycythemia requiring partial exchange transfusion, and hyperbilirubinemia. hospital course: summary of hospital course during this interim period is as follows: 1. respiratory- the infant has remained stable in room air. he has had no apnea of prematurity. 2. cardiovascular - the infant has remained hemodynamically stable with an intermittent murmur which is clinically consistent with pps. 3. fluids, electrolytes and nutrition - the infant has been advanced slowly on enteral feeds. he has tolerated his feeds well. he is currently showing good weight gain on either mother's milk or premature enfamil 24 kilocalories per ounce. he received gavage feedings until his oral motor skills improved, and is currently on an ad lib schedule taking approximately 150ml/kg/day. weight on discharge is 2.525 kg 4. gastrointestinal - the infant had a rebound bilirubin checked on which was 7.8. he has not received phototherapy since that time and has only mild facial jaundice on exam. 5. hematology - the infant is status post a partial exchange transfusion. most recent hematocrit on was 56. 6. infectious disease - he has had no signs of infection and has not received antibiotics. 7. neurology - the infant has a normal neurologic examination. due to his gestational age, he has not received a screening head ultrasound and will not require any specific follow up. 8. sensory - hearing screen was normal. the infant does not require screening ophthalmologic examination for retinopathy of prematurity due to his mild course and gestational age greater than 32 weeks. condition on discharge: good. discharge disposition: discharge to home. primary pediatrician: dr. of medical associates. care/recommendations: feeds at discharge - mother's milk or premature enfamil 24 cal/oz. medications - ferrous sulfate (25mg/ml) 0.2ml po qd, multivitamin 1ml po qd carseat test - passed newborn screen - the infant had a normal newborn screen. immunizations - 1. hepatits b vaccine was given prior to discharge. 2. synagis was given on prior to discharge given gestational age plus 2 additional risk factors (smokers in the home and 14 month old sibling who will be in day care). our criteria is for respiratory syncytial virus prophylaxis from through for infants who meet any of the following criteria: i. born at less than 32 weeks; ii. born between 32 and 35 weeks with two of the three of the following - daycare during respiratory syncytial virus season, with a smoker in the household, neuromuscular disease, airway abnormalities or school-age siblings; or iii. 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 caregivers should be considered for immunization against influenza to protect the infant. discharge diagnosis: 1. prematurity - unchanged 2. need for gavage feeding - resolved 3. status post respiratory distress 4. status post polycythemia secondary to twin/twin transfusion 5. status post rule out sepsis , m.d. dictated by: medquist36 d: 07:11 t: 07:25 job#: procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours parenteral infusion of concentrated nutritional substances insertion of endotracheal tube other phototherapy prophylactic administration of vaccine against other diseases umbilical vein catheterization circumcision hearing examination, not otherwise specified exchange transfusion diagnoses: neonatal jaundice associated with preterm delivery other preterm infants, 2,000-2,499 grams polycythemia neonatorum 33-34 completed weeks of gestation twin birth, mate liveborn, born in hospital, delivered without mention of cesarean section other transitory neonatal electrolyte disturbances need for prophylactic vaccination and inoculation against leishmaniasis placental transfusion syndromes affecting fetus or newborn
