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 an 83-year-old male with history of parkinson's who was found at the bottom of a flight of stairs leading to his basement. he was found by his sister. was conscious when found but was unable to recall the events. the ambulance was called and the patient was noted to have a gcs of 15. on arrival to the emergency room the patient still had a gcs of 15 and was complaining only of left shoulder pain. he also sustained two lacerations to his forehead. past medical history: parkinson's disease, status post exploratory laparotomy for small bowel obstruction, history of strangulated hernia, pulmonary embolism, status post ivc filter placement. medications: sinemet and amantadine. physical examination: vital signs were temperature 96.8, heart rate 75, blood pressure 146/54, satting 100% on face mask. he was alert and awake with coma scale of 15. pupils were equally round and reactive to light, 3 mm bilateral, extraocular movements intact. there were two large lacerations on his forehead. the first was on the right side of his forehead and was approximately 7 cm in length and was curved. the other was on the left side of his forehead and was 5 cm and was straight. tympanic membranes were clear bilaterally. trachea was midline. lungs clear to auscultation bilaterally. his chest was stable. there was no crepitus. heart was regular rate and rhythm without murmur. abdomen was soft, nontender, non distended. there was a well healed midline surgical scar. his rectal was guaiac negative with normal sphincter tone. the patient has an enlarged prostate. extremities were warm and without signs of trauma. he had palpable dorsalis pedis pulses bilaterally and no deformities. he was complaining of left shoulder pain with movement. his back was non tender with no stepoffs or deformity. laboratory data: initial laboratory studies showed a white blood cell count of 10.4, hematocrit 34.3, platelet count 183,000, sodium 143,potassium 4.4, chloride 105, co2 31, bun 21, creatinine 0.9, glucose 145, amylase 52, lactate 2.9, pt 13.1, ptt 25.4, inr 1.2. toxicology screen was negative. a trauma series was obtained which showed advanced degenerative changes at the c spine, multiple left sided rib fractures posteriorly including ribs 2 through 8, and a distal left clavicle fracture. subsequent films of the patient's lumbar and thoracic spine showed a compression deformity of l1 of uncertain age, severe degenerative changes and an ivc filter in place. ct of the head was obtained which showed a small subfalcine subdural hemorrhage and intraventricular hemorrhage. a dedictated left shoulder film confirmed a distal left intraarticular clavicular fracture. in light of the patient's subdural hematoma and multiple fractures, he was admitted to the intensive care unit. neurosurgery and orthopedics were consulted. the patient had q one hour neuro checks and his systolic blood pressure was maintained less than 140 with lopressor. he was loaded with dilantin and then continued at 100 mg po tid of dilantin. orthopedics followed up patient for the clavicular fracture and determined that he only needs a splint for treatment. the patient's neuro checks remained stable and a repeat head ct performed the day after the trauma showed a stable subdural hematoma without any signs of worsening. a feeding tube was placed for nutritional purposes. the patient was followed by physical therapy and occupational therapy while in the hospital. the patient remained completely stable without any worsening neurologic signs or symptoms. on hospital day #4 he was transferred to the hospital . by hospital day #5 he was doing well, he was tolerating food without difficulty as long as he was fed. the patient self discontinued his feeding tube. a family meeting was held between the case manager and the patient and his sister and it was determined that he would benefit from a stay at a rehabilitation facility. discharge medications: sinemet 50/200 one tablet po q a.m., ?????? tablet po q noon, ?????? tablet po q dinner and one tablet po q h.s., amantadine 100 mg po q noon, lopressor 50 mg po bid, hold for systolic blood pressure less than 100, heart rate less than 65, percocet po q 4 hours prn severe pain or tylenol 650 mg po q 4 hours prn pain. discharge diagnosis: 1. status post fall. 2. subdural hematoma. 3. parkinson's. 4. left clavicular fracture. 5. superficial laceration times two to the forehead. 6. rib fractures of ribs 2 through 8 posteriorly on the left. , m.d. dictated by: medquist36 procedure: enteral infusion of concentrated nutritional substances thoracentesis closure of skin and subcutaneous tissue of other sites diagnoses: unspecified pleural effusion open wound of forehead, without mention of complication paralysis agitans accidental fall on or from other stairs or steps subdural hemorrhage following injury without mention of open intracranial wound, with no loss of consciousness closed fracture of clavicle, unspecified part closed fracture of seven ribs 

Answer: The patient is high likely exposed to
