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: the infant was born at 26 and 6/7 weeks gestation by cesarean section for fetal heart rate decelerations. the mother is a 30 year old gravida i, now para i, woman. her prenatal screens were blood type o positive, antibody negative, rubella immune, rpr nonreactive, hepatitis surface antigen negative, and group b strep unknown. this pregnancy was reportedly uncomplicated until the mother presented to hospital on the day prior to delivery with decreased fetal movement and was found to have some fetal heart rate decelerations. she was then transferred to for further care and was noted to have oligohydramnios. at that time, she received betamethasone. the infant was in breech presentation. a fetal heart rate bradycardia prompted emergent cesarean delivery. the infant emerged requiring bag and mask ventilation. his apgar was three at one minute and seven at five minutes. his birth weight was 880 grams (50th percentile), birth length 34 centimeters (25 to 35th percentile) and head circumference was 23.5 centimeters (10th percentile). physical examination: his admission physical examination revealed an extremely premature infant. anterior fontanelle soft and flat, mobile sutures. palate intact. eyes open and eyelids not fused. breath sounds slightly coarse with mild retraction on ventilator. the heart was regular rate and rhythm, no murmur. mild soft abdominal distention, no organomegaly. immature but age appropriate male genitalia. patent anus and age appropriate tone and reflexes. hospital course: respiratory status - the infant was intubated in the delivery and he weaned to nasopharyngeal continuous positive airway pressure on day of life number fifteen. he then successfully weaned after many attempts to nasal cannula oxygen on day of life number fifty-seven. he has had a persistent oxygen requirement and at discharge he is on nasal cannula oxygen 150cc, flow of 100 percent oxygen. the infant was treated with caffeine citrate for apnea of prematurity on day of life number six until day of life number sixty-one. his last episode of apnea of prematurity occurred on . he began treatment with diuril for chronic lung disease on day of life number twelve and he continues on diuril at the time of discharge at 20 mg/kilogram/dose twice a day. he has had intermittent doses of lasix given for chronic lung disease throughout his hospitalization with minimal changes in oxygen requirements and further attempts at diuresis with lasix were discontinued after diagnosis of nephrocalcinosis. on physical examination at discharge, he has baseline mild to moderate subcostal retractions and nasal cannula oxygen. his lungs are clear and equal. he does have some intermittent nasal stuffiness. an arterial blood gas done on shows ph 7.39/paco2 50/ pao2 107/hco3 31. cardiovascular status - the infant has remained on normotensive throughout his nicu stay. he was treated with indocin for a patent ductus confirmed by echocardiogram on day of life number four. on day of life number six, a follow- up echocardiogram showed no patent ductus. his echocardiogram showed an otherwise functionally normal heart. an echocardiogram done on , by request of the pulmonary service to rule out pulmonary hypertension was significant for the following findings: pulmonary hypertension with a right ventricular systolic pressure greater than half the left ventricular pressure. trivial tricuspid regurgitation. no mitral regurgitation. patent foramen ovale with right to left flow. mild right ventricular dilatation. no aortic or pulmonary stenosis. no patent ductus. qualitatively good biventricular systolic function. his blood pressure during his nicu stay have been systolic in the 70s, diastolic in the 30 to 40 range, and mean blood pressure in the 50s. he continues to have an intermittent grade i/vi systolic ejection murmur at the left upper sternal border. on examination, he is pink and well perfused on nasal cannula oxygen. his liver edge is one centimeter below the right costal margin. fluids, electrolytes and nutrition status - his weight at discharge is 3740 grams. his length at discharge is 50 centimeters and head circumference 35 centimeters. enteral feeds were begun on day of life number eight and reached full volume feeds on day of life number seventeen. enteral feeds were then stopped due to a septic ileus for seven days and resumed on day of life number twenty-eight. he then reached full volume feeds on day of life number thirty-four and then advanced to a maximum of 30 calories per ounce of expressed breast milk. at the time of discharge, he is eating 24 calorie per ounce breast milk. he attained full oral feedings on . the mother plans to pump breast milk and give it by bottle. she initially attempted to breast feed but felt that the infant fed better from the bottle. potassium chloride supplements were begun on day of life number thirty-four. his current dose is 4 meq orally twice a day. electrolytes done on showed na 136 k 4.5 cl 101 hco3 24. gastrointestinal status - the infant was treated with phototherapy for hyperbilirubinemia of prematurity from day of life number one to day of life number ten. his peak bilirubin occurred on day of life number two and was total 4.7 with direct of 0.3. septic ileus on day of life number twenty-three concurrent with staph scalded skin syndrome required one week of bowel rest. genitourinary system - an abdominal ultrasound on , revealed bilateral hydrocele, no evidence of inguinal hernia. the left testicle positioned mainly in the inguinal canal but moving into the scrotal sac intermittently. bilateral renal stones. his blood urea nitrogen and creatinine on , were done. hematology status - the infant's blood type is o positive. he received two transfusions of packed red blood cells during his nicu stay, the last one on . his hematocrit and reticulocyte count on , and , were done. he is receiving supplemental iron at 4 mg/kilogram/day while he is receiving all breast milk feeding. infectious disease status - the infant was started on ampicillin and gentamicin at the time of admission for sepsis suspected. the antibiotics were discontinued after 48 hours when the blood cultures were negative and the infant was clinically well. he was then started on vancomycin and gentamicin on day of life number four for a clinical decompensation. these were discontinued after 48 hours. he remained off antibiotics until day of life twenty-one when he was begun on vancomycin and clindamycin and topical bactroban for staphylococcus scalded skin syndrome. the culture sensitivities allowed change to oxacillin on day of life number twenty-six and he then completed a seven day course of that. on day of life number thirty-eight, he was again started on vancomycin and gentamicin for a clinical decompensation. both antibiotics were discontinued after 48 hours when he was clinically well and the blood cultures remained negative. he has remained off antibiotics since that time. neurology - the infant has had five head ultrasounds during his nicu stay. all have been within normal limits, and the last one was on . sensory - audiology - hearing screening was performed with automated auditory brain stem responses and he passed with both ears. ophthalmology - the eyes were examined most recently on , and showed regressing retinopathy of prematurity with retinopathy stage i, zone three, four o'clock hour in the right eye and immature vessels in the left eye. a follow- up examination is scheduled for him on . psychosocial -
