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: the patient is a 49-year-old gentleman who was working on a roof when he lost his balance and fell off the roof scaffolding on the way down, ultimately hitting the left side of his body on the ground. he said he did not hit his head. there was no loss of consciousness. he complained only of low back pain. there was no numbness or weakness in the extremities after the fall. he was seen at an outside hospital where a l1 burst fracture was found with some retropulsion. past medical history: (past medical history includes) 1. c5-c6 discectomy in . 2. he has had a tracheostomy. 3. carpal tunnel bilaterally. 4. bilateral degenerative joint disease of the knees. allergies: no known drug allergies. medications on admission: he takes vicodin. social history: the patient is a four pack per day smoker for 10 years. he drinks two six-packs of beer per week. physical examination on presentation: physical examination revealed blood pressure was 147/92, heart rate was 77, respiratory rate was 16, and oxygen saturation was 99% on room air. temperature was 99.2. in general, the patient was awake and alert. in no acute distress. coma scale was 15. head, eyes, ears, nose, and throat examination revealed pupils were equal, round, and reactive to light. cranial nerves were intact. neck examination revealed a cervical collar was in place. the trachea was midline. chest was nontender with equal breath sounds. the abdomen was soft and nontender. extremity examination revealed 5/5 strength in all four extremities. sensation was intact throughout all four extremities. the pelvis was stable. his rectal examination was guaiac-negative with normal tone. his neurologic examination revealed the patient awake and oriented. cranial nerves ii through xii were intact. pupils were 3 mm to 2mm. extraocular movements were full. no pain to palpation over his head. no otorrhea or rhinorrhea. no neuropathic sign. motor strength was in both the upper and lower extremities. he had normal sensation. rectal tone was reported, as previously reported by the trauma team. his reflexes were one and symmetric throughout. pertinent laboratory values on presentation: laboratory data revealed white blood cell count was 9.1, hematocrit was 43.4, and platelet count was 224. sodium was 136, potassium was 3.7, blood urea nitrogen was 13, and creatinine was 1. albumin was 4.2. calcium was 9. ast was 29 and alt was 18. pertinent radiology/imaging: a computed tomography of his lumbar region showed an l1 burst fracture with retropulsion and multiple fragments. hospital course by issue/system: the patient was admitted to the intensive care unit where neurologic checks were monitored very closely every one hour. he was fitted for tlso brace. plain films were needed. a magnetic resonance imaging of his spine for t12 through l1 serially were recommended. he was placed on logroll precautions. the magnetic resonance imaging of his lumbar spine showed a compression fracture of l1 with retropulsion of the bone into the canal was noted. there was evidence of canal stenosis with approximately 50% of spinal canal compromised. there was no definite evidence of abnormal signal in the spinous process region. there was a left focal left-sided disc protrusion at l3-l4 with compromise of the thecal sac. the patient was monitored on in the intensive care unit where his vital signs were stable. his hematocrit remained at 40.9. he remained neurovascularly intact. he was waiting for a tlso brace, and he remained on logroll precautions. he was transferred to the floor on . on , his pain was under control. his motor strength in his lower extremities were full. his sensation was intact. he received upright films, and a brace, and a physical therapy consultation. the patient had difficulty obtaining standing films where he needed a significant amount of pain medications. at that time, dr. did discuss with the patient his inability to bear weight or ambulate, and he did advise the patient to proceed with surgical decompression and stabilization, and that would hopefully early mobilization. it was discussed that he would have a retroperitoneal l1 vertebrectomy with a t12 through l2 fusion using a titanium cage and plate device. the risks, benefits, and alternatives were discussed with the patient. on , the patient did have a l1 vertebrectomy and t12 through l2 fusion using a titanium cage and plate device. the patient tolerated the procedure well. he was monitored overnight in the intensive care unit, and he was given propofol for sedation. he proceeded to chest x-ray postoperatively, and it was within normal limits. he was kept on the ventilator overnight. also postoperatively, the patient was started on kefzol 1 g q.8h. the patient was also on empiric coverage with levofloxacin 500 mg q.24h. postoperatively, his incision was clean, dry, and intact. on , the propofol was discontinued, and the patient was extubated. postoperatively, the patient did have a chest tube in place. on , his postoperative hematocrit was 28.6. he had an inr of 1. his - drain had put out 80 cc. the patient was also on a dilaudid patient-controlled analgesia with good pain control and was receiving ativan as needed. on , the patient was neurologically intact. he was transferred to the surgical floor. his nasogastric tube was discontinued. he had a brace in place. he started to increase his activity using the brace. his chest x-ray on showed a slight increased patchy left retrocardiac opacity on the left which was concerning for possible pneumonia. therefore, the patient was continued on levaquin for that. there was no pneumothorax noted. as mentioned, on , the patient was moved to the regular surgical floor. he was awake, alert, and oriented. his motor strength in his lower extremities was bilaterally. he was started on a clear liquid diet and was seen by physical therapy. he also was continued with his chest tube, which on showed no evidence of pneumothorax and a resolving opacity in the right middle lung zone was improving. there was difficulty with occupational therapy as the patient was refusing to do any activity with them, and they agreed to come back and assist him on . on , the patient did work more with physical therapy and occupational therapy. his occupational therapy was discontinued. the patient was not interested in any help with them. on , the patient did see rheumatology for bilateral foot pain for four days. he has a history of gout. they made some recommendations for nonsteroidal antiinflammatory drugs; however, given his postoperative concerns, history of gastritis, that was not started. they did recommend that if his symptoms worsened we could consider prednisone or colchicine. physical therapy continued to work with the patient. on , physical therapy discontinued any acute need to continue therapy with them. the patient had his tlso brace adjusted prior to discharge. the patient had a bilateral lower extremity examination which was . he was neurologically intact. discharge instructions/followup: 1. the patient was to keep an appointment with dr. in one month and to have x-rays prior to his discharge. 2. the patient was to have his staples removed by . 3. the patient was to keep his incision clean, dry, and intact. 4. the patient was to follow up with the clinic for an appointment regarding his toe pain. medications on discharge: the patient was given a prescription for percocet one to two tablets q.4h. for pain (#30 dispensed). , m.d. dictated by: medquist36 procedure: lumbar and lumbosacral fusion of the anterior column, posterior technique other partial ostectomy, other bones insertion of interbody spinal fusion device diagnoses: pneumonia, organism unspecified pulmonary collapse other accidental fall from one level to another closed fracture of lumbar spine with spinal cord injury 

Answer: The patient is high likely exposed to
