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: baby was admitted to the nicu at approximately 48 hours of age for evaluation and treatment of significant hyperbilirubinemia. he was born weighing 3675 grams, a term gestation to a 20-year-old primip whose pregnancy was complicated only by gestational hypertension. labor was unremarkable. infant delivered by svd with apgars of 8 and 9. mother's prenatal screens are blood type o+, antibody negative, rpr nonreactive, hbsag was not available at the time of admission (however, later it was determined that the mother was hbsag negative). the infant had done well in the normal nursery, was ad lib. breast feeding with no supplementation. the bilirubin was done at 36 hours of age which showed a bilirubin level of 20.8. a cbc and reticulocyte were sent. the hematocrit was 43. the infant was ordered to start under phototherapy. 4 hours later a repeat bilirubin level was sent, and the bilirubin had gone up to 23.3/0.5. at that time the infant was admitted to the nicu. the baby's blood type is b+, but the dat was also positive. physical examination on admission: the birth weight is 3675, 90th percentile; length is 52 cm, which is 90th percentile; head circumference is 34 cm, which is 50th-75th percentile. on exam the infant is jaundiced but active in term. has heent that is normal. normal heart rate and rhythm. normal s1, s2. no murmurs. lungs are clear and equal. abdomen is benign. no hepatosplenomegaly. normal male genitalia. neurologic exam is normal for term infant. normal cry. normal tone. summary of hospital course by systems: respiratory: the infant remained in room air since admission to the nicu and has had no issues with apnea. has maintained normal breathing rate and rhythm, with no increased work of breathing. cardiovascular: the infant has maintained a normal cardiovascular status- has not presented with any murmurs, has normal heart rate and rhythm, normal blood pressure, and is well perfused. fluids, electrolytes, nutrition: due to the significant bilirubin increase on admission, the patient was briefly made npo and started on iv fluids of d10 with electrolytes. he was also given a single normal saline bolus due to question of some dehydration from sole breast feeding. the infant was started on feedings approximately 6 hours after admission to the nicu when the bilirubin level did start to drop. no electrolytes have been measured. the most recent weight is 3625 grams on . gi: after initiating of phototherapy with quadruple phototherapy on admission to the nicu, the bilirubin level quickly started to drop down. within 3 hours of initiation of phototherapy on admission to the nicu, bilirubin dropped to 20. the next subsequent day it had continued to decrease. phototherapy was slowly withdrawn with a bilirubin level of 10.9/0.3 on . the phototherapy was completely discontinued, and a rebound bilirubin level was drawn 8 hours after that. that bilirubin level was unchanged at 10.9/0.3. the infant was discharged to home and returned to the nicu on for a follow-up bilirubin. the level was 11.3/0.4. hematology: as stated previously, the infant's blood type is b+. coombs' positive. the hematocrit has stayed stable. the hematocrit on admission was 43, and it was 42.3 on . the patient has remained pink and well perfused. a reticulocyte count was done on , which was 10.8. infant has required no blood product transfusion. infectious disease: there have been no infectious disease issues at this time. neurology: the infant has maintained a normal neurologic exam for a term male infant. sensory/audiology: a hearing screen was performed with automated auditory brainstem responses, and infant passed in both ears on . condition at discharge: good. discharge disposition: home with the family. name of primary pediatrician: , md , nnp pediatrics. (p) , (f) . care recommendations: ad lib. p.o. feedings of breast milk or breast feeding with supplementation of special care 20 with iron. medications: none. discharge instructions: follow-up bilirubin levels will need to be done as an outpatient to monitor the bilirubin status and rule out ongoing hemolysis. state newborn screen was sent on . results are pending. immunizations received: infant received the hepatitis b vaccine on . immunizations recommended: synagis rsv prophylaxis should be considered from through for infants who meet any of the following 3 criteria: 1) born at less than 32 weeks gestation, 2) born between 32 and 35 weeks with 2 of the following: 1) daycare during 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 6 months of age. before this age, and for the 1st 24 months of a child's life, immunization against influenza is recommended for household contacts and out-of-home caregivers. follow-up appointment: follow-up appointment should be scheduled with the pediatrician within 2 days of discharge. discharge diagnoses: 1. abo incompatibility. 2. hyperbilirubinemia. dr., 50-595 procedure: parenteral 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 single liveborn, born in hospital, delivered without mention of cesarean section routine or ritual circumcision hemolytic disease of fetus or newborn due to abo isoimmunization 

Answer: The patient is high likely exposed to
