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 42 year old male with a 25 year history of hepatitis c infection, child's b cirrhosis, variocele bleed times one, status post tips one and a half weeks ago, who presents with melena. the patient reports that he was in his usual state of health until approximately two weeks prior to the admission, at which time he had hematochezia that led to the loss of approximately two liters of blood, medical intensive care unit admission, and emergent placement of tips following hemodynamic stabilization. the patient was discharged from the hospital feeling well until the day of admission, when he felt lightheaded. he denies any syncope or fall, however, he continued to feel dizzy. he had a bowel movement that was melenic times two. because before prior admission, he also felt lightheaded, he decided to come to the emergency room. the patient reports fatigue. he denies any easy bruising or bleeding anywhere besides gastrointestinal tract. he denies any shortness of breath, chest pain. he denies urinary or upper respiratory symptoms. he denies nausea or vomiting, fevers, constipation or diarrhea. past medical history: 1. a 25 year history of hepatitis c infection contracted secondary to intravenous drug abuse in . genotype 1a, diagnosed in . treated with regulated interferon as well as vibrovirin for 12 weeks with failure to eradicate the virus. the patient is currently in a pilot study of interferon versus colchicine, and is on colchicine 0.6 mg twice a day. said his last viral load was 256,000. 2. child's b cirrhosis with a biopsy in , showing grade ii to iii inflammation. 3. portal hypertension. 4. gastropathy with esophagogastroduodenoscopy in showing abnormal vascularity of fundus in antrum and in , cirrhotic liver with portal hypertension. 5. non-suspicious liver mass, although patient has had multiple nodules seen in his liver. 6. grade i esophageal varices status post leak two weeks prior to the admission. social history: the patient denies any alcohol since . he reports intravenous drug use in , none since then. the patient denies any tobacco use. family history: significant for coronary thrombosis in his father. allergies: no known drug allergies. medications on admission: 1. lactulose. 2. colchicine 0.6 mg twice a day. 3. nadolol 60 mg p.o. q. day. 4. aldactone 100 mg p.o. q. day. 5. accupril 10 mg p.o. q. day. 6. somata for sleep. physical examination: on admission, vital signs 98.6 f. for temperature; pulse 76; blood pressure 101/61; respiratory rate 17; o2 saturation 98% on room air. in general, the patient is alert and responsive in no apparent distress. heent: icteric sclerae and frenulum. no lymphadenopathy, no thyromegaly, no jugular venous distention appreciated. lungs are clear to auscultation bilaterally. heart: regular rate and rhythm with ii/vi crescendo/decrescendo systolic murmur. abdomen soft, nontender, nondistended. no hepatosplenomegaly appreciated. extremities without edema or erythema. skin jaundiced. rectal with dark stools, positive for heme. neurological: the patient is mildly anxious, alert and oriented times three. pupils are round and reactive to light, 3 to 2 millimeters bilaterally. extraocular movements intact. the patient's sensation is intact. facial movements are intact. hearing is intact bilaterally. tongue protrudes midline. sternocleidomastoid and trapezius muscles intact. laboratory findings: on admission, alpha-fetoprotein 12.3. chem-7 with sodium 136, potasium 4.1, chloride 101, bicarbonate 25, bun 31, creatinine 0.9, glucose 99. cbc showed white count of 12.6 with 70 neutrophils, 17 lymphocytes, 7.5 monocytes, 4 eosinophils. hematocrit 33.4 with three plus macrocytosis and two plus anisocytosis. platelet count 160. alt 53, ast 89, alkaline phosphatase 149, total bilirubin 3.5. inr 1.3. urinalysis was pending. hospital course: in summary, the patient is a 49 year old gentleman with a 25 year history of hepatitis c infection, child's b cirrhosis, varicocele bleed and status post tips one and a half weeks ago, presenting with melena, most likely representing another upper gastrointestinal bleed. while in the emergency room, the patient was seen by the gi fellow and due to the fact that the patient was hemodynamically stable, his melena subsided and hematocrits remained at approximately 30, the decision was made not to start octreotide. overnight, the patient's hematocrit drifted from 33 to 28, and he was transfused one unit packed red blood cells. he underwent an abdominal ultrasound to evaluate the patency of the tips. the initial report noted decreased velocity of the flow in the tips and thrombus in ivc. a repeat ultrasound by vascular tech showed occlusion of tips without ivc thrombus. the patient was continued on his protonix and all the medications that could effect his blood pressure including nadolol and aldactone were held. he was transfused another unit of packed red blood cells on his way to interventional radiology for revision of his tips. the patient tolerated the procedure well. overnight, he was monitored in the medical intensive care unit and remained hemodynamically stable. a repeat ultrasound revealed patent tips with flow rate in the range of 65 to 127. there is patent and appropriate direction flow in the portal vein, hepatic vein and the hepatic arteries. following additional treatment with packed red blood cells the patient's hematocrit remained at 32. he was restarted on his outpatient medications with blood pressures in the 120s. prior to the discharge, the patient was seen by dr. from transplant surgery. possible renal splenic shunt occlusion was considered due to lower flows than desired through the tips. the patient is to have a follow-up ultrasound in one week. additionally, he is to follow-up with his hepatologist and dr. . discharge diagnoses: 1. hepatitis c infection. 2. child's b cirrhosis. 3. portal hypertension. 4. grade i esophageal varices status post tips revision. 5. status post variceal bleed times two. 6. status post transfusion of four units of packed red blood cells. medications on discharge: 1. lactulose. 2. colchicine 0.6 mg p.o. twice a day. 3. nadolol 50 mg p.o. twice a day. 4. aldactone 100 mg p.o. q. day. 5. accupril 10 mg p.o. q. day. 6. sonata for sleep. dr., 12-899 dictated by: medquist36 procedure: injection of anesthetic into spinal canal for analgesia intra-abdominal venous shunt diagnoses: thrombocytopenia, unspecified cirrhosis of liver without mention of alcohol portal hypertension other specified surgical operations and procedures causing abnormal patient reaction, or later complication, without mention of misadventure at time of operation esophageal varices in diseases classified elsewhere, with bleeding acute hepatitis c without mention of hepatic coma mechanical complication of other vascular device, implant, and graft 

Answer: The patient is high likely exposed to
