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 is a 1515 g baby boy at 35 weeks gestational age as twin b, admitted to the neonatal intensive care unit for management of prematurity. the infant was to a 35-year-old, gravida 2, para 0, mother with maternal blood type 0+, antibody negative, hepatitis c surface antigen negative, rpr nonreactive, gbs unknown. medical history included a "hole in her heart" requiring a catheterization procedure when she was 12 years old, possibly consistent with a vsd or asd but with no subsequent cardiological issues. there was an obstetrical history of miscarriage in . this pregnancy was a product of ivf and resulted in monochorionic/diamniotic twins. there were concerns for 1) twin a with mild pulmonary stenosis diagnosed on fetal echocardiogram at , 2) twin b had fetal growth restrictions. both had normal amniotic fluid volumes and normal biophysical profiles. the neonatology service was present at delivery with apgar scores of 8 and 9. due to the fetal growth restrictions, the infant was transported to the neonatal intensive care unit for monitoring of transition and glucose homeostasis. hospital course: respiratory: was comfortable in room air from admission and has not had any active respiratory issues. cardiovascular: has maintained normal blood pressures and heart rates and has not had a murmur. no active cardiovascular issues. fluids/electrolytes/nutrition: he was initially started with ad lib p.o. feeds with a minimum of 60 cc/kg/day of premature enfamil 20. although he initially took p.o. intake moderately well, he quickly tired out and was unable to make his minimum volume of feeds. he was gradually advanced on volumes and caloric density of p.o. and gavage feeding. at the time of transfer, he was receiving 150 cc/kg/day of either mother's milk or neosure supplemented to 24 cal/oz, receiving it p.g. much more the p.o. this feeding immaturity is his primary active issue at this time. weight at the time of transfer was 1735 g. gastrointestinal: was initially started on phototherapy for a bilirubin level that peaked at 8.3 on . phototherapy was discontinued on with a subsequent rebound bilirubin of 5.9 on . he has had no subsequent bilirubin issues. hematology/infectious disease: there were no perinatal substance risk factors, and no cbc or blood cultures were sent, and has never been on antibiotics; however, on routine surveillance screening, was found to be mrsa positive on . since he and his twin have been co-bedding, the two have been on contact precautions subsequently. neurology: no head ultrasounds have been required. sensory: hearing screening was performed with automated auditory brain stem responses with normal results on . no ophthalmologic exams have been required. routine healthcare maintenance: hepatitis b immunization was administered on . state screen was sent on , but the specimen was unacceptable. a repeat newborn screen was sent on with results pending. a circumcision was performed on without complication. condition on discharge: stable. discharge disposition: nicu team b. primary pediatrician: dr. in . discharge diagnosis: 1. prematurity, feeding immaturity, status post hyperbilirubinemia, intrauterine growth restriction. , m.d. dictated by: medquist36 procedure: parenteral infusion of concentrated nutritional substances enteral infusion of concentrated nutritional substances other phototherapy prophylactic administration of vaccine against other diseases circumcision diagnoses: need for prophylactic vaccination and inoculation against viral hepatitis twin birth, mate liveborn, born in hospital, delivered by cesarean section neonatal jaundice associated with preterm delivery 35-36 completed weeks of gestation neonatal hypoglycemia routine or ritual circumcision other preterm infants, 1,500-1,749 grams 

Answer: The patient is high likely exposed to
