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: is the former 1.86 kg product o a 32-2/7 week gestation pregnancy born to a 31- year-old g1, p0 woman. prenatal screens: a positive, antibody negative, rpr nonreactive, rubella immune, hepatitis b surface antigen negative, group b strep status unknown. the pregnancy was complicated by spontaneous monochorionic- diamniotic twins with a lethal renal anomaly of twin a noted at 18 weeks gestation. the anomaly appeared to be bilateral multicystic dysplastic kidneys with bladder dilation and suspected posterior urethral valves. the other fetus appeared healthy with a normal fetal survey. pregnancy was followed with every two week ultrasounds by dr. to assess fluid and fetal well-being of twin b. the parents initially wanted reduction of twin a, but it was not recommended due to the monochorionicity of the pregnancy. she developed premature labor. presentation was vertex-vertex, but the mother requested cesarean section due to concerns regarding possible need for emergency cesarean section after delivery of twin a, due to stress in twin b. prenatally, it was planned to provide comfort care for twin a. the mother presented in preterm labor with cervical dilatation. there was no maternal fever, or fetal tachycardia, or other intrapartum risk factors for sepsis. she was not treated with antibiotics. there was a failed attempt at tocolysis with magnesium sulfate. the mother received one dose of betamethasone. she was taken to the or for elective cesarean section. this twin number two emerged with spontaneous cry, required blow-by o2, then positive pressure in the delivery room to support adequate color. apgars were 8 at one minute and 9 at five minutes. he was transferred to the neonatal intensive care unit for further evaluation and management of issues of prematurity and respiratory distress. physical exam upon admission to the neonatal intensive care unit: weight 1.86 kg, 65th percentile, length 44.5 cm, 60th percentile, head circumference 30.5 cm, 55th percentile. general: nondysmorphic with overall appearance consistent with gestational age. head, eyes, ears, nose, and throat: anterior fontanel soft and flat. red reflex deferred. palate intact. chest: intercostal retractions. minimal bilateral air entry. cardiovascular: regular, rate, and rhythm without murmur. two plus peripheral pulses including femorals. abdomen is slightly distended, but no hepatosplenomegaly. kidneys normal in size. three vessel cord. spine: normal back. extremities: stable hips. moving all, normal digits and creases. skin: well perfused, pink on o2. neurologic: normal tone and activity. hospital course by systems including pertinent laboratory data: 1. respiratory. required intubation and surfactant for his respiratory distress syndrome. initial ventilatory settings were a peak inspiratory pressure of 25 positive end expiratory pressure of five, intermittent mandatory ventilatory rate of 20 and 40 percent fraction of expired oxygen. he received one dose of surfactant. he weaned rapidly to low settings. he was extubated to room air by day of life one and continued on room air through the remainder of his neonatal intensive care unit admission. at the time of discharge, he is breathing comfortably with respiratory rates in the 30s to 50s. 2. cardiovascular. a murmur was noted on day of life number one with increasing intensity. a cardiology consult from was called, and the baby underwent a cardiac echocardiogram, which showed a moderate sized high muscular vsd. he is at risk for congestive heart failure but none has been evidenced to date. it is possible that the vsd may close on its own. the murmur remains audible at the time of discharge. will require followup with cardiology at with dr. and is scheduled to be seen on at 1:30 pm. 3. fluid, electrolytes, and nutrition. was initially npo and treated with intravenous fluids. enteral feeds were started on day of life number one and gradually advanced to full volume. his maximum caloric intake was 24 calories/ounce. he is being discharged on enfamil 24 calories/ounce. serum electrolytes were checked 3x in the first week of life and were all within normal limits. at the time of discharge, he is taking a minimum of 130 cc/kg/day. weight on the day of discharge is 2.27 kg with a length of 45.5 cm and a head circumference of 31 cm. 4. infectious disease. due to the unknown etiology of the preterm labor and his respiratory distress, was evaluated for sepsis. a white blood cell count was 9,000 with a differential of 26 percent polys, 2 percent bands. a blood culture obtained prior to starting intravenous antibiotics was no growth at 48 hours. he was treated pending the culture results with intravenous ampicillin and gentamicin, which were discontinued after 48 hours. 5. hematological. hematocrit at birth was 56.6 percent. did not require any transfusions of blood products. 6. gastrointestinal. required treatment for unconjugated hyperbilirubinemia with phototherapy. peak serum bilirubin occurred on day of life number five, total 9.2/0.3 for an indirect of 8.9. he received approximately six days of phototherapy. his rebound bilirubin on day of life 10 was a total of 6.5/0.2 direct for an indirect of 6.3. 7. neurological. maintained a normal neurological exam during admission and there are no neurological concerns at the time of discharge. 8. sensory. audiology. hearing screening was performed with automated auditory brain stem responses. passed in both ears. 9. psychosocial. twin expired within hours after delivery. the family has been grieving appropriately. social work has been involved with the family. the contact social worker is , and she can be reached at . discharge condition: good. discharge disposition: home with the parents. primary pediatrician: dr. , pediatrics, , , , phone number , fax number . care and recommendations at the time of discharge: 1. feeding ad lib. enfamil 24 calories/ounce. 2. no medications. 3. was evaluated in his car seat. he was observed for 90 minutes without any episodes of bradycardia or oxygen desaturation. 4. state newborn screens were sent on and with no notification of abnormal results to date. 5. hepatitis b vaccine was administered on . 6. immunizations recommended. synagis rsv prophylaxis should be considered from through for infants who meet any of the three criteria: 1. born at less than 32 weeks, 2. born between 32 and 35 weeks with two of three of the following: daycare during the rsv season, a smoker in the household, neuromuscular disease, airway abnormalities, or school-age siblings, or 3. with chronic lung disease. influenza immunization is recommended annually in the fall for all infants once they reach six months of age. before this age and for the first 24 months of the child's life, immunization against influenza is recommended for household contacts and out of home caregivers. 1. follow-up appointments scheduled: 2. appointment for evaluation and an echocardiogram on , at 1:30 p.m. with dr. clinic number at . their clinic is located on the of the building at . 3. appointment with dr. , primary pediatrician on wednesday, . discharge diagnoses: 1. prematurity at 32-2/7 weeks gestation. 2. twin number two of twin gestation. 3. respiratory distress syndrome. 4. suspicion for sepsis ruled out. 5. ventricular septal defect. 6. unconjugated hyperbilirubinemia. , procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube other phototherapy prophylactic administration of vaccine against other diseases diagnoses: need for prophylactic vaccination and inoculation against viral hepatitis observation for suspected infectious condition twin birth, mate liveborn, born in hospital, delivered by cesarean section respiratory distress syndrome in newborn neonatal jaundice associated with preterm
