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: patient has had multiple back surgeries in the past l4, s1 fusion in ', l3, s1 fusion in , l2, 3 microdiscectomy . patient is having continuing pain radiating to the leg, neuropathy in the feet. ct shows severe spinal stenosis compressed thecal sac. past medical history: 1. diabetes mellitus. the patient's diabetes is controlled with oral medications. last hemoglobin a1c is 7.9. 2. hypertension. 3. gerd. relevant past surgical history: 1. the patient had a l2, 3 microdiscectomy. 2. l3-s1 fusion. 3. in l4-s1 fusion. medications as an outpatient: 1. atenolol. 2. moexipril. 3. hydrochlorothiazide. 4. glyburide. 5. peroxetine. 6. oxycodone. 7. ms contin. allergies: questionable codeine allergy causing hallucinations. physical examination: generally: obese male, who seems uncomfortable. regular, rate, and rhythm, no murmurs, rubs, or gallops. abdomen is obese, soft, nontender, no masses, no hepatosplenomegaly. pupils are equal, round, and reactive to light and accommodation, constricted, romi, 2+ carotid, no thyromegaly. extremities: upper extremity strength, thigh flexion, decreased sensation in the legs bilaterally. foot: 4+/5 foot dorsiflexion, 2+ femoral pulses dp and pt pulses bilaterally. feet are warm bilaterally. assessment and plan: l2-3 spinal stenosis, spondylolisthesis. plan is l2-3 decompression, fusion pedicle screw, icbg. brief hospital course: on , the patient underwent l2-3 fusion decompression. patient tolerated the procedure well postoperatively in the pacu. in the icu the patient was extubated without event. postoperative hematocrit was 29.8 down from 34.9 preoperatively. postoperative white blood cell count was 8.8. postoperative chemistries were within normal limits. glucose is 192. magnesium was slightly low at 1.4. patient was placed on bed rest of head of bed elevated greater than 30 degrees. patient was treated with ancef perioperatively 1 gram iv q8. venodynes and subq heparin were initiated for dvt prophylaxis. patient's pain was managed with a morphine pca. he had two drains placed and both were set on suction postoperatively. his laboratories on postoperative day two were within normal limits. hematocrit was slightly increased to 30.9. patient's diet was advanced at that time which he tolerated well. he was out of bed with a brace at all times, which was a tlso. foley was d/c'd without events. patient was transferred to the floor. patient had standing lumbosacral films, which showed good placement of hardware and no interval change. patient's drain output was monitored closely. hematocrits trended down on postoperative days three and four to the high 20 range, and he was transfused two additional units of packed red blood cells. there is a questionable transfusion reaction, however, the patient remained stable at all times. the patient received a total of 5 units of packed red blood cells during this stay. patient was mildly febrile on postoperative day four leading him to stay in the hospital for an extra couple of days. hemovacs were d/c'd without events. postoperatively, the patient was out of bed with physical therapy doing well. he was kept in the hospital because of a mild fever and hematocrits trending down. there was no source of fever identified. it was attributed to atelectasis. hematocrit was rechecked after transfusion and day of discharge was 31.1. discharge instructions: patient will be discharged home with services for physical therapy and wound check. patient will be returning in two weeks for staple removal and in three weeks for x-rays. he will receive morphine sulfate p.o. for pain and iron for his anemia. , m.d. dictated by: medquist36 procedure: lumbar and lumbosacral fusion of the anterior column, posterior technique excision of bone for graft, other bones fusion or refusion of 2-3 vertebrae diagnoses: unspecified essential hypertension diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled pulmonary collapse iron deficiency anemia, unspecified other and unspecified disc disorder, lumbar region precipitous drop in hematocrit acquired spondylolisthesis 

Answer: The patient is high likely exposed to
