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: prenatal laboratory studies: blood type b positive, hepatitis b surface antigen negative, rpr nonreactive, rubella immune and gbs was unknown. prenatal course: the prenatal course was notable for: 1. maternal chronic hypertension since and mother was on atenolol during this pregnancy. 2. history of heroin use with the last usage being two months prior to delivery. the patient's mother was currently on methadone at time of delivery. 3. maternal depression: the mother was on paxil p.r.n. and had had none in the last two months. 4. preterm labor: there was no maternal fever. the gbs status was unknown, but the mother did receive antibiotics greater than four hours prior to delivery. the baby was vaginally and had of 8 and 9, got some initial blow-by o2 for central cyanosis but pinked up quickly and did well in the delivery room. the patient was admitted to the neonatal intensive care unit for observation for signs and symptoms of withdrawal and for additional work-up. physical examination: on admission to the neonatal intensive care unit, the patient's weight was 2,270 grams, was well appearing with no respiratory distress. anterior fontanel was open and flat. there was a small caput noted. the palate was intact. nares were patent. the breath sounds were clear bilaterally. there was a normal s1 and s2 with no murmur. the abdomen was soft, nontender and nondistended. there was no evidence of hepatosplenomegaly. the extremities were warm and well perfused. the hips were stable. the anus was patent and the spine was intact. summary of the hospital course by systems: 1. respiratory: the patient needed initial blow-by o2 but has had no subsequent oxygen requirement and has remained stable on room air since birth with saturations in the high 90s. the patient never required c-pap or intubation. 2. cardiovascular: there was no murmur noted and the patient has been cardiovascularly stable through the entire hospital course. 3. fluids, electrolytes and nutrition: the patient was started on pe-20 formula, initially with a minimum of 40 cc per kilo per day, but was quickly advanced to ad lib and has been taking ad lib pe-20 very well, feeding and exceeding minimum requirements. on day of this dictation, the patient's current weight was 2,120 grams. 4. gastrointestinal: the patient did have a mild elevation in bilirubin but it peaked at approximately 8 and did not require phototherapy. 5. hematology: the patient never required any transfusions and has been stable. 6. infectious disease: the patient got an initial rule out sepsis for preterm labor and unknown gbs status. cbc was sent which was benign. blood cultures were no growth at greater than 48 hours and the ampicillin and gentamicin were continued for only 48 hours and subsequently discontinued. 7. neurology: the patient did start to show signs of withdrawal on day of life one. the patient was irritable and fussy, was difficult to console. had nas scores less than 6. however, by day two, the nas scores did reach levels of 6 to 8 and neonatal opium solution was started on , for nas scores of greater than 8. the patient was started initially on neonatal opium solution of 0.3 cc p.o. q. four hours on a solution that contained 0.4 mg per ml, for a total of 0.12 mg q. four hours. this level was able to bring the nas scores down to 2 to 4 and the patient remained stable overnight on and on the morning of with nas score of 2, the dose was weaned by 10% to 0.27 cc of neonatal opium solution. the current wean was set up for a wean of 10% for every three scores of the nas that was less than 8. 8. social: a urine toxicology screen was sent at approximately 12 hours of age and was negative, however, a urine was not obtained and several urines were missed prior to the urine tox screen being sent. center's social worker was involved with the family with the dss worker that has this case. the mother is currently seeing psychiatry for long-standing depression and is followed at hospital since , for methadone maintenance. a 51a was filed on this admission and she also had a 51a filed for her 11-month-old who currently is an open dss case. her current worker is . the telephone number is . social work here has felt that the mother has been engaged and does want to do the best for her infant and has been making attempts to be very engaged. 9. sensory: audiology hearing screen has not yet been performed but will be performed prior to discharge. ophthalmologic findings: the patient was not examined as it was not applicable for gestational age. condition at discharge: the patient's condition at transfer to the newborn nursery was good. interim discharge disposition: to the newborn nursery. the name of the primary pediatrician is comp and the phone number there is . the fax number is . care and recommendations: 1. the patient's feeding at discharge is pe-20 ad lib; would continue on the pe-20 for now due to gestational age. 2. medications: neonatal opium solution currently at 0.27 cc p.o. q. four hours. the plan is to wean that at 10% for every three nas scores that are less than 8. 3. state newborn screening status is pending. 4. immunizations received: the patient will receive hepatitis b. discharge diagnoses: 1. prematurity. 2. neonatal abstinence syndrome. , m.d. dictated by: medquist36 procedure: prophylactic administration of vaccine against other diseases diagnoses: need for prophylactic vaccination and inoculation against viral hepatitis observation for suspected infectious condition single liveborn, born in hospital, delivered without mention of cesarean section other preterm infants, 2,000-2,499 grams drug withdrawal syndrome in newborn 

Answer: The patient is high likely exposed to
