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 25-year-old white male, status post motorcycle versus automobile accident. the patient was not wearing a helmet and was found unresponsive to pain at the scene. he was subsequently intubated and noted to have an 11-cm laceration of his anterior neck and a spike wound to his left temporal scalp. the patient was sedated after being transported to an outside hospital with versed, ativan, and lopressor and was subsequently transferred to for trauma and neurosurgical management. physical examination on presentation: on initial physical examination, the patient was sedated and did not open his eyes to voice. he localized pain with his bilateral upper extremities by sternal rub. he did not follow commands, nor did he attempt to communicate; although, he was put on a ventilator. his coma scale in the trauma bay was 70. the patient was afebrile and vital signs were stable throughout his initial of trauma management. hospital course: secondary to weaning of sedation, the patient began to move all extremities. a head ct in the trauma bay revealed a right superior parietal occipital contusion of less than 1-cm in size as well as a right temporal contusion. there was also evidence of pneumocephalus with a left mastoid air/fluid level adjacent to the left temporal bone nondisplaced fracture. there was no evidence of midline shift. in summary, the patient had a closed head injury. a extra ventricular drain was subsequently placed by the neurosurgical team under sterile conditions. cerebrospinal fluid drained after the first pass, and the patient tolerated the procedure well. the patient was also loaded with dilantin and repleted with isotonic fluids. the patient was also consulted by ear/nose/throat surgery, and they were responsible for evaluating the patient's neck laceration. it was determined that none of the major neurovascular structures were injured. on secondary survey, it was noted that the patient also had injured his left ankle. however, there was no evidence of fracture by x-ray. toxicology screens were notable for a positive benzodiazepines, cocaine, and marijuana use. the patient was subsequently transferred to the trauma intensive care unit where he was closely monitored for changes in neurologic status over the next several days. the patient became progressively more responsive and alert, and it was noted in his left upper and lower extremities were slightly weaker on the left side. the patient's cranial nerve function were intact as were his sensory dermatomes. the patient's extra ventricular was removed on day five of admission, and he was subsequently transferred to the floor. the patient was consulted on a regular basis by physical therapy and occupational therapy. it was noted that he suffered from gait instability as well as cognitive deficits. however, the patient's mental status and orientation had improved throughout his stay and he continued to make progress. the patient did not tolerate doses of haldol and benzodiazepines for sedation. although the patient could be redirected and somewhat cooperative during the day, he often had difficulty cooperating during the night. because of his reluctance to stay in bed, he was routinely restricted to his bed with soft and hard restraints. on several occasions a tent was used to restrict the patient to his bed to prevent him from falling. on discharge, the patient was capable of walking 500 feet with equal step lengths. he could climb one flight of stairs with railings on the right side. there was decreased tone in his left upper extremity. with regard to sedating the patient, it is best to avoid using benzodiazepines and haldol in lieu of his negative reaction to these drugs during this admission. medications on discharge: 1. trazodone 50 mg p.o. q.h.s. 2. tylenol as needed for pain. discharge status: to rehabilitation. discharge instructions: a regular diet. medications on discharge: as per above as needed. discharge followup: the patient should see mr. at the in two weeks with a repeat head ct. , md dictated by: medquist36 procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more parenteral infusion of concentrated nutritional substances insertion of endotracheal tube intravascular imaging of intrathoracic vessels arterial catheterization diagnoses: cocaine abuse, unspecified open wound of scalp, without mention of complication sedative, hypnotic or anxiolytic abuse, unspecified cannabis abuse, unspecified closed fracture of base of skull without mention of intra cranial injury, unspecified state of consciousness closed fracture of mandible, unspecified site open wound of other and unspecified parts of neck, without mention of complication cerebellar or brain stem contusion without mention of open intracranial wound, unspecified state of consciousness motor vehicle traffic accident involving collision with other vehicle injuring motorcyclist 

Answer: The patient is high likely exposed to
