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 22-year-old male who reportedly rolled down a in a barrel with moving all 4 extremities at the scene. however, became combated and was intubated and sedated at an outside hospital. cat scan of his head showed a left convexity lens-shaped hemorrhage deep to the skull fracture, which had increased in size from his outside hospital film. there is subarachnoid and intraparenchymal hemorrhage surrounding edema of the right anterior cranial fossa, which was unchanged from his outside films. there was a third extraaxial hemorrhage located laterally along the right convexity, which was unchanged from his outside films. he also had a left occipital fracture at the base of his skull. a t-spine cat scan was negative for any thoracic fractures. hospital course: the patient was admitted to the trauma intensive care unit where he was monitored with serial cat scans, which did not show any additional increase in size of his hemorrhages. he was placed on decadron, dilantin, and mannitol. he received one dose of mannitol. he was kept sedated and intubated for the first 24 hours. in the evening of , he had a repeat cat scan, which did not show any increased hemorrhage on his cat scan. he underwent a diagnostic cerebral angiogram, which showed no evidence of carotid or vertebral injury or any problems with his middle meningeal branch. during angiogram, there was a question of expanding epidural. he went down for a stat head ct, which showed again a lens-shaped hemorrhage along the left inner convexity, which measured 9 mm in its greatest width, which was not significantly changed compared to the prior study. he returned back to the intensive care unit where he remained neurologically intact and he was extubated on the morning of . his fluid balance was kept euvolemic to negative. his pupils were 3 to 2. he was moving all extremities spontaneously. his blood pressure was kept in the 120 to 130 range. he had a repeat head ct on , which showed no change in multiple foci of hemorrhage within the brain. on , he was transferred to the step down surgical unit where he was continued with q.1 hour nerve checks and close monitoring. he remained awake, alert, had difficulty at times with orientation and sometimes required one-to-one supervision. on , he was seen by speech therapy, who found him stage 2, who cleared him for regular diet. he was then transferred to the surgical floor where he continued to make good progress. he was seen by physical therapy who felt that he would need some assistance with mobility and balance training. however, he ambulated with minimal difficulty. he was reassessed on , and they felt he was safe to be discharged home. also on , he had flexion-extension films, which showed no cervical or spinal instability. however, he had complained of some neck pain the 2 days prior to having these films done and he was out of the 72 hour window to receive mri assessment for ligamentous injury. so, it was recommended that he maintain in a cervical collar for the next 2 weeks' and follow-up again with flexion-extension films. discharge diagnoses: closed head injury. epidural hematoma. multiple cerebral contusions. occipital fracture. discharge instructions: keep his hard collar on at all times. continue on dilantin. no heavy lifting greater than 10 pounds. no driving until he follows up. he should call dr. office if he develops headache which is not relieved by medication or dizziness. he should have his dilantin level checked by his primary care physician. should follow-up with dr. on with flexion-extension films; those are done at at 11 o'clock in the morning, and then follow-up with a cat scan at 11:30, and then follow-up with dr. at 12:30. followup medications: 1. dilantin 200 mg 1 p.o. b.i.d. 2. tylenol as needed. 3. percocet 1 to 2 tablets p.o. q. 4 to 6 hours. on his discharge day of , his dilantin level was 1.0. he was loaded with 1 g of dilantin and his medication was increased to 200 mg b.i.d., which he should follow-up with a primary care physician to have his dilantin level checked. , procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours enteral infusion of concentrated nutritional substances arteriography of cerebral arteries arterial catheterization diagnoses: closed fracture of base of skull with subarachnoid, subdural, and extradural hemorrhage, unspecified state of consciousness other accidental fall from one level to another cervicalgia 

Answer: The patient is high likely exposed to
