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 patient was the 1890 gram product of a 33 and week twin gestation, born to a 28 year-old, primiparous mother. the mother's pregnancy was apparently uncomplicated until she presented on the morning of delivery with preterm labor and rupture of membranes. prenatal screens: 0 positive blood type. antibody negative. hepatitis surface antigen negative. rpr nonreactive. rubella immune. group b strep unknown status. the patient was delivered via cesarean section. this baby emerged and was vigorous. his apgars were 8 and 8. he was brought to the nicu after visiting with his parents. hospital course by systems: cardiovascular/respiratory: the patient initially manifested mild respiratory distress prompting treatment with cpap. he required low oxygen requirements through the first day and a half of delivery. on day 2, increasing oxygen requirements and work of breathing prompted intubation and treatment with surfactant for a total of 3 doses. diagnosis was hyaline membrane disease. on day 3, he was noted to have a murmur consistent with a patent ductus arteriosus. he was treated with a course of indomethacin. subsequently, clinical evidence of pda resolved. a repeat echocardiogram at the time when the patient had a murmur consistent with peripheral pulmonary stenosis showed the absence of a pda. there was suggestion of peripheral pulmonic stenosis. this study was done on . the patient has had mild apnea and bradycardia episodes, consistent with gestational age. he was treated with caffeine citrate therapy from the second through the 3rd weeks of life. he has been without significant apnea and bradycardia episodes since 5 days prior to discharge. he has had mild bradycardia episodes related to feeding 3 days prior to discharge. the parents are comfortable with recognizing his feeding patterns and cues related to intolerance. fluids, electrolytes and nutrition: the patient was initially maintained n.p.o. on iv fluids. he was given parenteral nutrition while receiving his indomethacin therapy. he was gradually increased on feeds, beginning on the 6th day of life. he progressed without difficulty to full volume feeds. he is currently receiving ad lib feedings with a minimum of 120 cc/kg per day goal. he is currently receiving breast feedings. expressed breast milk is administered as breast milk supplemented with special care formula to a total of 24 calories per ounce. it has been suggested that this continue through the immediate post discharge period and be assessed for the need for continuation based on growth rates. weight at the time of discharge is 2935 grams. renal: an ultrasound done in follow-up of prenatal studies showed mild bilateral hydronephrosis. the patient was begun on amoxicillin prophylaxis which continues at the time of discharge. plan is for outpatient vcug. parents are aware of this need for follow-up. infectious disease: the patient was initially placed on ampicillin and gentamycin because of concerns of sepsis, given the unexplained preterm labor. cbc at the time of admission showed a hematocrit of 45.4 with a white count of 9.5. there were 13 polys and 1 band. platelet count was 265,000. a repeat cbc on was similarly unremarkable in terms of sepsis risk. as noted previously, the patient has been treated with amoxicillin prophylaxis for genitourinary, for potentially increased risks of urinary tract infections. gastrointestinal: the patient was advanced on feedings with difficulty. the patient had a maximum bilirubin of 8.7 on the 4th day of life. he was treated with phototherapy during the first week of life. his most recent bilirubin was 6.3 over 0.2 on the . neurologic: the patient has manifested a normal neurologic examination throughout his hospital stay. given his advanced gestational age, head ultrasonography was not indicated. routine health care maintenance. ophthalmologic screening was not indicated given the patient's advanced gestational age and clinical course. car seat test performed prior to discharge showed . hearing screen prior to discharge showed . the patient received hepatitis b immunization, initial dose on . screening specimens were sent to the regional newborn screening program on and . no abnormalities have been noted. the patient is scheduled for circumcision prior to discharge. primary pediatrician: , md, . disposition: discharged to home. feeds at discharge: ad lib breast feeding, breast milk or special care 24 calorie formula for bottle feedings. iron and vitamin supplementation. iron supplementation is recommended for preterm and low birth weight infants until 12 months corrected age. all infants fed predominantly breast milk should receive vitamin d supplementation at 200 i.u. (may be provided as a multi-vitamin preparation) daily until 12 months corrected age. immunizations recommended: synagis rsv prophylaxis should be considered from through for infants who meet any of the following four criteria: (1) born at less than 32 weeks; (2) born between 32 weeks and 35 weeks with two of the following: day care during rsv season, a smoker in the household, neuromuscular disease, airway abnormalities or school age siblings; (3) chronic lung disease or (4) hemodynamically significant congenital heart disease. influenza immunization is recommended annually in the fall for all infants once they reach 6 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. this infant has not received rotavirus vaccine. the american academy of pediatrics recommends initial vaccination of preterm infants at or following discharge from the hospital if they are clinically stable or at least 6 weeks but fewer than 12 weeks of age. follow-up appointments: outpatient scheduling of vcug to be arranged with primary pediatrician. discharge diagnoses: 1. 33 and week preterm twin infant. 2. hyaline membrane disease. 3. rule out sepsis. 4. patent ductus arteriosus. 5. peripheral pulmonic stenosis. 6. bilateral mild hydronephrosis. 7. apnea and bradycardia of prematurity. , procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified parenteral infusion of concentrated nutritional substances diagnostic ultrasound of heart insertion of endotracheal tube non-invasive mechanical ventilation insertion of other (naso-)gastric tube other phototherapy prophylactic administration of vaccine against other diseases diagnoses: need for prophylactic vaccination and inoculation against viral hepatitis twin birth, mate liveborn, born in hospital, delivered by cesarean section respiratory distress syndrome in newborn neonatal jaundice associated with preterm delivery primary apnea of newborn neonatal bradycardia patent ductus arteriosus other preterm infants, 1,750-1,999 grams 33-34 completed weeks of gestation septicemia [sepsis] of newborn ostium secundum type atrial septal defect other obstructive defects of renal pelvis and ureter 

Answer: The patient is high likely exposed to
