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: past medical history: 1. hepatitis c. 2. cirrhosis, child's a. 3. varices. 4. hypertension. allergies: the patient has no known drug allergies. admission medications: 1. protonix. 2. inderal. social history: the patient currently lives in a group home. positive history of iv drug abuse and alcohol. physical examination on admission: vital signs: afebrile, heart rate 100, blood pressure 127/61, respiratory rate 12, saturating 98%. general: intubated and paralyzed, assist control. heent: blood coming out of nares. active bleeding out of mouth, ng tube placed. tube placed via og. heart: tachycardiac. normal s1 and s2. lungs: bilateral breath sounds anteriorly and laterally. abdomen: distended, positive bowel sounds, tympanic. extremities: no clubbing, cyanosis or edema. laboratory/radiologic data: on admission, sodium 138, potassium 4.0, chloride 106, bicarbonate 25, bun 13, creatinine 1.5, glucose 154. white blood cell count 6.6, hematocrit 28.3, platelets 133,000. inr 1.2. fibrinogen 123, amylase 92. abgs on admission 7.33/41/467. chest x-ray on admission: low lung volumes. et tube in place, approximately 3 cm above the carina. perihilar haziness. hospital course: during the icu course, the patient received 23 units of packed red blood cells, 12 units of ffp, and 3 of cryo. he underwent procedure on with placement of tube. this resulted in 1 liter of bloody output. the patient had no further variceal bleeding since . he did have positive blood cultures on and resulting in initiation of penicillin for gram-positive alpha streptococcus. the patient was extubated on and did well on room air with oxygen saturation in the high 90s. he did have some mental status changes in the intensive care unit which were thought to be due to sedation with fentanyl and possible hepatic encephalopathy. these quickly resolved after the patient was weaned off the fentanyl drip. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more insertion of endotracheal tube fiber-optic bronchoscopy enteral infusion of concentrated nutritional substances gastric lavage injection of anesthetic into spinal canal for analgesia intra-abdominal venous shunt insertion of sengstaken tube diagnoses: cirrhosis of liver without mention of alcohol acute posthemorrhagic anemia pulmonary collapse acute respiratory failure other shock without mention of trauma infection and inflammatory reaction due to other vascular device, implant, and graft esophageal varices in diseases classified elsewhere, with bleeding hematemesis 

Answer: The patient is high likely exposed to
