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: family history is notable for two prior children requiring treatment for hyperbilirubinemia. the last was a full term infant girl born in , who was admitted to the nicu with coombs+ hyperbilirubinemia and required an exchange transfusion in addition to phototherapy. that infant's blood type was b+/coombs +. physical exam: wt 3395 gm (down 160 grams from birth weight, approx 5%). vs: t 98.3 hr 140s rr 60-70s bp 81/52 (59) gen: active and vigorous, no significant distress skin: warm, dry, jaundiced heent: fontanelles soft and flat, palate intact, ears/nares normal neck: supple, no lesions chest: cta, no g/f/r cardiac: rrr, no m abdomen: soft, no hsm, no mass, active bs gu: normal circumcised male, anus patent, femoral pulses 2+ ext: no lesions neuro: appropriate tone and activity, intact moro/grasp/suck in nicu, repeat bilirubin and other laboratory studies sent, and infant was started on intensive phototherapy and iv hydration. labs: bili (9:40pm): 22.0/0.4 bili (11:30pm, before phototherapy): pending lytes: pending cbc: 15.1>37.4<394 diff pending retic: pending blood cx: sent blood type: b+, coombs negative imp: term infant, now day of life 2, with significant indirect hyperbilirubinemia. overall infant is well-appearing. degree of hyperbilirubinemia is greater than would be expected for physiologic jaundice, even in the setting of mild dehydration and limited enteral intake. the most likely contributing factor is hemolysis due to abo incompatibility, given the mildly low hematocrit and family history despite the negative coombs test; the reticulocyte count will be useful. another consideration is g6pd deficiency, given this is a male black infant. sepsis also should be considered, although doubtful given infant's overall appearance. if bilirubin increases any further or does not respond to intensive phototherapy, exchange transfusion will have to be considered. procedure: other phototherapy diagnoses: observation for suspected infectious condition single liveborn, born in hospital, delivered without mention of cesarean section unspecified fetal and neonatal jaundice 

Answer: The patient is high likely exposed to
