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: this is a 44-year-old male with extensive past medical history including hepatitis b and c, history of esophagus, history of esophageal varices, history of esophageal/gastric ulcers as well as history of upper gi bleed, who presents with 3 episodes of "coffee- ground like hematemesis" this morning. reports binge drinking approximately 10 beers, several shots of tequilla and injecting cocaine at approximately 6 to 11 p.m. he finally went to sleep, which was unrestful, and awoke at 3:00 a.m. with a sensation of nausea, vomiting, and nearly vomited. thirty minutes later, he went to the bathroom and vomited 3 times in succession approximately 500-700 cc of emesis without bright red blood, felt lightheaded with chills, and subsequently vomited again with 1 episode of bright red blood. no noting of melena or hematochezia. past medical history: hepatitis b and c. history of barrett's esophagus. history of esophageal varices. portal hypertensive gastropathy. history of esophageal ulcers presumed peptic. history of splenectomy. history of upper gi bleed in , unclear etiology, required 8-12 units of packed red blood cells. subsequent admission in for hematemesis. egd showed gastritis, barrett's, and gastroesophageal ulcers. allergies: no known drug allergies. medications: protonix 40 b.i.d. social history: heavy alcohol use since age of 8, history of iv drug use, positive tobacco. family history: positive for liver disease in the father and alcoholism in the father. physical examination: vital signs on admission, temperature 98.1 degrees, blood pressure 104/68, heart rate 95, respiratory rate 10, 98 percent on room air. the patient is a middle-aged male, lying in bed, in no acute distress. heent: pupils equal, round, and reactive to light. moist mucous membranes. no lymphadenopathy. neck: soft. cardiovascular: regular rate, s1, s2. no murmurs, rubs, or gallops. lungs: clear to auscultation bilaterally. abdomen: normal bowel sounds, soft, mild right upper quadrant tenderness with distension. extremities: no clubbing, cyanosis, or edema. neurologically oriented x3. no asterixis. grossly nonfocal. laboratory data on admission: notable for white count of 11.7 with 40 percent neutrophils, 47 percent lymphocytes, 6 percent eosinophils, and no bands. hematocrit 42.8 and platelets 236. chemistries: sodium 140, potassium 4.3, chloride 103, bicarbonate 23, bun 18, creatinine 0.7, glucose 81, alt 72, ast 143, amylase 75, alkaline phosphatase 111, ldh 256, total bilirubin 0.9, and albumin 3.8. ck is 872, mb is 4, and troponin is less than 0.51. ekg showed sinus rhythm at 90 beats per minute, normal axes, normal intervals, no active signs of ischemia, no significant st-t wave changes. chest x-ray showed no acute cardiopulmonary disease. hospital course by system: gi bleed: the patient was emergently transferred to the intensive care unit and seen by gi. egd was performed showing small hiatal hernia, barrett's esophagus, varices at the ge junction, portal hypertensive gastropathy. no active blood in the stomach. there is an ulcer in the proximal stomach body likely the cause of the patient's melena. erythema and friability noted in the duodenal bulb in the second portion of duodenum compatible with duodenitis and no duodenal ulcers were visualized. the patient was monitored in the icu, hematocrit was checked every 6 hours, 2 peripheral ivs were maintained at all times. the patient was typed and crossed, started on iv protonix b.i.d., started on octreotide drip, was made n.p.o. an h. pylori was checked, which was ultimately negative. stools were guaiaced. over the course of hospitalization, the patient's hematocrit remained stable. there were no further episodes of active or occult bleeding. the patient did not require blood transfusion. alcohol dependence abuse/polysubstance abuse: social work was consulted regarding substance abuse. the patient was given precautions of ativan per ciwa scale, started on multivitamin, folate, and b vitamins. the patient did not have any active complications from alcohol withdrawal and was maintained on the ciwa scale. however, the patient's mental status was poor throughout majority of admission. delirium: psychiatry was consulted regarding delirium. the patient noted to have auditory hallucinations, thought ultimately to be secondary to large doses of ativan and mild hepatic encephalopathy in the setting of underlying liver disease and the new gi bleed. the patient's ativan was discontinued. the patient was given lactulose. the patient's electrolytes were checked and repleted as needed. the patient was monitored with a sitter and psychiatry was consulted to aid in further management of delirium. the patient's tsh, folate, and b12 were checked and found to be within normal limits. the patient had episodes of trying to leave the hospital. the patient had required restraints for his safety secondary to delirium or wanting to climb out of bed. the patient was given a sitter. code purple was called approximately 3 times during the hospital course. the patient remained relatively re-directable during hospital course without significant use of medications or restraints. at the time of discharge, the patient's mental status began to improve. the patient was able to think clearly and demonstrated recognition of his poor prior behavior. the patient requesting a shelter versus detox to help himself at the time of discharge. cirrhosis/portal hypertension: this is thought to be worsening either secondary to alcohol discontinuance or medication effect. the patient's lfts were monitored and remained stable. there is no current changes in management that were made during this hospital course, except patient was started on lactulose with good results. prophylaxis was a ppi, bowel regimen, and a ciwa scale. the patient's code status remained full. condition on discharge: stable. discharge status: to home with referral to shelters and detox units. discharge diagnoses: gastric ulcer. gastrointestinal bleed. alcohol abuse/dependence. cirrhosis/portal hypertension. alcoholic hepatitis. alcoholic withdrawal. narcotic withdrawal. invasive procedure: egd. discharge medications: 1. protonix 40 mg p.o. b.i.d. 2. multivitamins p.o. q.d. 3. vitamin b12 50 mg p.o. q.d. 4. thiamine 100 mg p.o. q.d. 5. nicotine patch, 1 patch transdermal q.d. discharge instructions: the patient was strongly instructed to abstain from alcohol, abstain from heroin and cocaine. the patient was requested to see the gi physicians in 6 weeks. followup: followup is with gi on . followup is also with primary care doctor, dr. in weeks.7 dr., 12-929 procedure: other endoscopy of small intestine diagnoses: chronic hepatitis c without mention of hepatic coma alcoholic cirrhosis of liver portal hypertension opioid type dependence, continuous chronic or unspecified gastric ulcer with hemorrhage, without mention of obstruction drug-induced delirium chronic viral hepatitis b without mention of hepatic coma without mention of hepatitis delta cocaine dependence, continuous other and unspecified alcohol dependence, continuous 

Answer: The patient is high likely exposed to
