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 46 year old male who developed dyspnea on exertion, palpitations and left abdominal pain and was diagnosed with pancytopenia in . bone marrow aspirate was consistent with myelodysplastic syndrome, mds. he was started on procrit at the time and aranesp and treated with arsenic which was discontinued in . white blood cell count increased to 300,000 with 87 percent myeloblasts and he was treated with leukophoresis followed by induction chemotherapy 7 plus 3, in , without infectious complications. a repeat bone marrow biopsy on , showed hypercellular marrow with myeloid maturation and diffuse reticular fibrosis. he was given another course of chemotherapy in , and went home on . he received platelets and blood transfusions during this time. on , he saw dr. in clinic where he was noted to have increasing blast count. he was asked to come into the hospital for admission of chemotherapy. his appetite has been good and he has had improving energy recently. he denies fevers, chills, nausea, vomiting, shortness of breath, cough, chest pain, diarrhea or dysuria and his weight has increased by five pounds in the past week. past medical history: aml as described above with induction chemotherapy 7 plus 3 in . vocal cord polyps removed in . history of optic disc elevation, right greater than left. medications: 1. valtrex one gram q. day. 2. diflucan 100 mg p.o. q. day. 3. ciprofloxacin 500 mg p.o. q. day. 4. neupogen. 5. neumega 7 cc subcutaneously q. day. 6. procrit subcutaneously weekly. allergies: no known drug allergies. family history: father with alcoholic cirrhosis. no history of malignancy. social history: he is married and lives with his wife in . quit alcohol at 28 years old. quit tobacco approximately five months ago. quit marijuana approximately one year ago. exposure to barium and lead in the past. physical examination: in general, well dressed, well nourished man in no apparent distress appearing slightly fatigued. vital signs are temperature of 98.3 f.; heart rate 95; blood pressure 160/80; respiratory rate 20; saturation of 100 percent on room air. heent: pupils equal, round and reactive to light. extraocular muscles intact. oropharynx is clear. chest is clear to auscultation bilaterally with no wheezes, rales or rhonchi. heart is regular rate and rhythm, normal s1, s2, ii/vi systolic murmur, question flow murmur. abdomen soft, nontender, nondistended, positive bowel sounds, positive hepatosplenomegaly. extremities with no clubbing, cyanosis; one plus pitting edema bilateral lower extremities. neurological: five out of five strength in all extremities. cranial nerves ii through xii intact. back tender over the bone marrow biopsy sites. no hematoma. pertinent laboratory data: hematocrit is 24.0; white blood cell count is 4.7 with 51 percent polys, 2 bands, 34 lymphs, 19 monos, one eo, 29 percent blasts. platelets of 195. inr is 1.3, fibrinogen 297, ldh 393, uric acid 6.8, creatinine 0.8, potassium 3.9, anc is 959, alt 73, ast 30, alkaline phosphatase 86. hospital course: 1. oncology: the patient presented with aml with increasing blasts on smear. the patient underwent chemotherapy with the flag protocol, which included fludarabine, ara-c and gcsf. the patient had an echocardiogram on presentation which was normal. he had an uncomplicated course during his hospitalization stay. he got gcsf continual and his hematocrit continued to drop during the hospitalization course. 2. hematology: the patient's transfusion hematocrit threshold was 25.0. he was given blood transfusions in- house to maintain a hematocrit of greater than 25 as well as platelet transfusions to be greater than 10. he had an episode where he required steroids, decadron times one, prior to platelet transfusion as this had been occurring during his previous hospitalization stay at an outside hospital. 3. infectious disease: the patient was maintained on bactrim, diflucan and acyclovir for prophylaxis. levaquin was added once his anc was less than 500. 4. diet, fluid, electrolytes and nutrition: the patient was maintained on a neutropenic diet. when counts decreased, then he was maintained on intravenous fluids. once his hydration reached an equilibrium after chemotherapy, he was switched to kvo during the day and maintenance fluids at night times one liter. 5. access: the patient had a left portacath already in place on admission. he received a right triple lumen catheter at the interventional radiology in the right subclavian. he had some pain associated at the site and got oxycodone as needed. 6. vertigo: the patient experienced a one time episode of vertigo while getting blood and while getting high dose ara-c. otoscopic examination was unremarkable. he had an mri with gadolinium which was negative for any abnormalities except for mastoid and sphenoid fluid. vertigo resolved. 7. ophthalmology: the patient had a history of a visual field cut defect and optic disc swelling right greater than left. the patient had ophthalmology consulted in- house. they recommended an orbital mri to rule out leukemic infiltrate. the patient had a fine cut mri of the orbits which was negative for a leukemic infiltrate or mass effect. followup of a lumbar puncture that was performed in the patient prior to admission was obtained from the outside hospital and was negative for malignant cells or any infectious process. the remainder of the hospital course will be dictated in a future discharge addendum summary by the next intern taking care of this patient. , m.d. procedure: insertion of intercostal catheter for drainage continuous invasive mechanical ventilation for less than 96 consecutive hours continuous invasive mechanical ventilation for 96 consecutive hours or more insertion of endotracheal tube pericardiocentesis thoracentesis closed [endoscopic] biopsy of bronchus systemic arterial pressure monitoring transfusion of packed cells open biopsy of lung transfusion of other serum injection or infusion of cancer chemotherapeutic substance transfusion of platelets allogeneic bone marrow transplant without purging diagnoses: acute and subacute necrosis of liver acute kidney failure, unspecified unspecified septicemia severe sepsis acute respiratory failure aspergillosis pneumonia in aspergillosis acute myeloid leukemia, without mention of having achieved remission 

Answer: The patient is high likely exposed to
