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 56-year-old white male with diabetes, hypertension, hepatitis c, and a history of intravenous drug abuse who has been followed by dr. of podiatry for a left heel ulcer which developed several weeks prior to admission. the patient was referred to dr. for further evaluation and treatment. past medical history: 1. diabetes. 2. hypertension. 3. hepatitis c. 4. history of intravenous drug abuse. past surgical history: 1. cholecystectomy. 2. bilateral fifth toe amputation. allergies: no known drug allergies. medications on admission: 1. nph insulin 12 units subcutaneously q.a.m. 2. nph insulin 4 units subcutaneously at supper. 3. methadone 40 mg p.o. q.d. 4. cardizem-cd 240 mg p.o. q.d. 5. lasix 40 mg p.o. q.d. 6. tylenol p.o. as needed. 7. oxygen via nasal cannula as needed. family history: family history was noncontributory. social history: the patient lives at the greenery in for the previous seven years. he is a cigarette smoker. he does not drink alcohol. he has a history of intravenous drug abuse. he has been using a cane and/or wheelchair for mobility. physical examination on presentation: general physical examination revealed an alert and cooperative white male in no acute distress. heart examination revealed a regular rate and rhythm without murmurs. the lungs were clear bilaterally. the abdomen was soft and nontender. extremities revealed left heel ulceration was present. pulse examination revealed femoral pulse was palpable bilaterally. neurologic examination was nonfocal. pulses had dopplerable signals bilaterally. neurologic examination was nonfocal. pertinent laboratory values on presentation: admission laboratories from revealed white blood cell count was 14.9, hemoglobin was 10.2, hematocrit was 33.4, and platelets were 324,000. sodium was 138, potassium was 5.1, chloride was 106, bicarbonate was 24, blood urea nitrogen was 29, creatinine was 1.6, and blood glucose was 106. urinalysis on was negative. a culture of the left heel ulcer from showed methicillin-resistant staphylococcus aureus, moderate growth. pertinent radiology/imaging: a chest x-ray showed no acute pulmonary disease. electrocardiogram revealed intermittent sinus rhythm at a rate of 46, ectopic atrial focus was present. hospital course: the patient was admitted to the hospital on . he was placed on the mucomyst protocol and hydrated prior to angiogram in the cardiac catheterization laboratory on . the cardiology service was consulted for preoperative clearance. an echocardiogram on showed normal left ventricular wall thickness and cavity size. the left ventricular systolic function was normal with an left ventricular ejection fraction of greater than 55%. the patient was cleared for surgery. mavik was recommended for better blood pressure control. t his was started on . approximately three hours after the first dose, the patient's systolic blood pressure dropped to 80. the patient's only complaint was nausea. the patient was transferred to surgical intensive care unit for close monitoring. a dopamine drip was used to manage his systolic blood pressure. cardiac isoenzymes were cycled and were negative. it was determined that a larger dose of mavik was given than recommended. the patient's blood pressure returned to baseline. the patient was scheduled for surgery. on , the patient underwent an uneventful left superficial femoral artery endarterectomy with a dacron patch. at the end of surgery, the patient had a dopplerable left dorsalis pedis and posterior tibialis pulse. he received 2 units of packed red blood cells intraoperatively. the patient received several doses of kefzol perioperatively. the patient was started on lopressor; per postoperative beta blocker protocol. dr. , the patient's endocrinologist, followed the patient for diabetic management. physical therapy evaluated the patient for full weightbearing ambulation on his left foot using a healing sandal. the patient will continue to wear a multipoultice splint on his left leg when he is not ambulating. at the time of discharge, the patient's left thigh incision was intact. there was minimal serosanguineous drainage from the incision. his left heel ulcer is clean and without erythema. he will continue to have normal saline, wet-to-dry, dressing changes t.i.d. his incision will be swabbed with a betadine stick q.d. the patient had dopplerable signals at his pedal pulses bilaterally. the patient was to follow up with dr. in the office for staple removal in 10 days. medications on discharge: 1. methadone 40 mg p.o. q.d. 2. nph insulin 12 units subcutaneously q.a.m. 3. nph insulin 4 units subcutaneously at supper. 4. regular insulin sliding-scale q.i.d. 5. cardizem-cd 240 mg p.o. q.d. 6. lopressor 12.5 mg p.o. b.i.d. 7. lasix 40 mg p.o. q.d. 8. ecotrin 325 mg p.o. q.d. 9. heparin 5000 units subcutaneously b.i.d. 10. sucralfate 1 g p.o. q.i.d. 11. reglan 10 mg p.o. a.c. and q.h.s. 12. ranitidine 150 mg p.o. b.i.d. 13. calcium carbonate 500 mg p.o. q.i.d. as needed. 14. percocet one to two tablets p.o. q.4h. as needed. 15. tylenol 325 mg to 650 mg p.o. q.4h. as needed. 16. oxygen via nasal cannula (to maintain oxygen saturations of greater than 92%). condition at discharge: condition on discharge was satisfactory. discharge status: return to home in . discharge diagnoses: 1. ischemic left heel ulcer. 2. left superficial femoral artery endarterectomy with dacron patch on . secondary diagnoses: 1. diabetes. 2. gastroparesis. 3. hypertension. 4. hepatitis c. 5. methicillin-resistant staphylococcus aureus (left heel). 6. history of intravenous drug abuse. , m.d. dictated by: medquist36 procedure: arteriography of femoral and other lower extremity arteries aortography repair of blood vessel with synthetic patch graft endarterectomy, lower limb arteries diagnoses: unspecified essential hypertension chronic hepatitis c without mention of hepatic coma diabetes with neurological manifestations, type ii or unspecified type, not stated as uncontrolled polyneuropathy in diabetes opioid type dependence, continuous atherosclerosis of native arteries of the extremities with ulceration ulcer of heel and midfoot gastroparesis 

Answer: The patient is high likely exposed to
