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 the present illness: the patient is a 47-year-old male with minimal past medical history admitted status post in which he was an unrestrained passenger, ran into a pole, and was found unconscious in the passenger seat. there was a witnessed seizure in the field and again at where he was loaded with dilantin. his gcs at was 5. no history could be obtained by the patient but per his sister in-law, he had been complaining of a headache, photophobia and was somnolent for two days prior to his motor vehicle accident. past medical history: 1. irritable bowel syndrome. 2. hypercholesterolemia. 3. seasonal allergies. 4. no history of heart or lung disease. admission medications: 1. lipitor. 2. prevacid. 3. viagra. 4. amoxicillin. 5. nasal decongestant, suspect for a recent sinusitis. allergies: the patient has no known drug allergies. family history: father and paternal grandfather with coronary artery disease, first mi in their 70s. social history: the patient denied tobacco, alcohol, or drug use. he states that he lives with his wife, has no children, and works as an apartment manager. of note, this admission, his wife has learned of his infidelity. social work was consulted. physical examination on admission: on initial presentation, he was intubated on propofol. the pupils were 2 mm with trace reactivity, 4 mm reduced to 2 mm when aroused. corneals were intact bilaterally. oculocephalic examination was unable to be done as the patient was in a c-spine collar. he was arousable to painful stimuli, withdrew all extremities to painful stimuli, and with arousal, there was spontaneous movement of all extremities. his lungs were clear. on cardiovascular examination, he had an s1 and s2 with no murmurs noted. the abdomen was soft with no hepatosplenomegaly. the extremities revealed no edema. laboratories and diagnostics: the admission white count was 17.0, decreased to within normal limits prior to discharge, initial hematocrit 43.5, stabilized in the range of 34-35. the chem-10 was within normal limits. the most recent dilantin level was 8.7 on . pt 13.0, inr 1.1, ptt 26.8. ct of the l-spine revealed a fracture of the right l1 transverse process. no other fracture or subluxation. the chest x-ray revealed no pneumonia or chf. ct of the head revealed no intracranial or extracranial hemorrhage, mass affect, or shift. no evidence of infarction. ventricle cistern and sulci are unremarkable. partial opacification of all paranasal sinuses. the rpr was nonreactive. the eeg revealed predominance of excessively drowsy and sleepy activity consistent with encephalopathic pattern versus sleep depravation. left ankle x-ray revealed medial and malleolar fracture with mild surrounding soft tissue swelling. left knee x-ray revealed no fracture or joint effusion. no fracture of the proximal left fibular head. blood cultures from revealed no growth until the time of this dictation. alt 61 on presentation, decreased to 33, ast 71, decreased to 26, alkaline phosphatase 60, ldh 551 on presentation, deceased to 396, total bilirubin 0.5. drug screen negative including alcohol but positive for opiates. the u/a revealed negative nitrate leukocyte esterase, red blood cells, white blood cells, occasional bacteria. csf from lumbar puncture on revealed bottle one 62 white blood cells, 525 red blood cells, 89% polys, 8% lymphocytes, 3% monocytes. bottle number four revealed 73 white blood cells, 460 red blood cells, 33% polys, 65% lymphocytes, 2% monocytes. csf lumbar puncture on bottle number one revealed 2 white blood cells, 1,250 red blood cells, 12 polys, 43 lymphocytes, 40 monocytes, 1 eosinophils, 4 mac. bottle number four revealed 1 white blood cell, 2,250 red blood cells, 36 polys, 24 lymphocytes, 36 monocytes, 4% eosinophils. enterovirus pcr is pending. hsv pcr is pending. total protein from csf tap 47, glucose 74, ldh 34. viral cultures from the csf revealed no growth to date. gram's stain negative. culture negative. fungal negative. cryptococcal antigen negative. acid-fast pending. head mri with neck mra to rule out vertebral dissection pending. hospital course: this is a 47-year-old male with no significant past medical history admitted status post mva with left medial malleolar fracture and l1 transverse process fracture noted to have 60-70 white blood cells on initial lp concerning for meningitis managed with iv antibiotics. 1. meningitis: the patient was noted to have 60-70 white blood cells on initial lumbar puncture with a confusing differential, unclear whether this is due to bacterial or viral origin. thus, the patient was started on ceftriaxone, vancomycin, and acyclovir. plan to continue ceftriaxone and vancomycin for a total of two weeks. the acyclovir will be continued pending results of the hsv pcr. the patient is being covered for possible hsv infection due to note of high-risk sexual activity in addition to rbcs in the csf consistent with an hsv infection but may be due to traumatic brain injury with diffuse axonal injury. 2. seizure: the patient was noted to have a witnessed seizure in the field and again at . likely this has occurred in the context of traumatic brain injury. an eeg was done and showed predominance of an excessively drowsy and sleepy activity consistent with an encephalopathic versus sleep-deprived state. no seizure activity was noted. the patient was loaded with dilantin and is currently taking dilantin p.o. 300 mg t.i.d. we will follow his dilantin level with a goal dilantin level of for seizure prophylaxis. the patient was maintained on seizure precautions; however, no seizure activity has been noted this admission. 3. fracture of the transverse process of l1: the patient was fitted with a lumbar corset and has been seen by physical therapy. recommendation for physical therapy two to four times per week for mobility and balance training, gait training, and patient education. the patient's pain from this fracture has been managed with p.r.n. tylenol and percocet. 4. left medial malleolar fracture: the patient's left lower extremity was casted. we managed his pain with p.r.n. percocet and tylenol. x-rays were done to rule out proximal fibular fracture which commonly is associated with this type of malleolar fracture. these x-rays were found to be negative. as stated above, the patient will need continued physical therapy. 5. pulmonary: the patient required intubation upon presentation for a hypoxia. he was extubated without difficulty on . upon transfer to the floor, he was quickly weaned off 2 liters nasal cannula to room air which he is currently saturating 92% on room air. 6. persistent low-grade fever: the patient was with a temperature maximum of 100.6, continuing to run low-grade fevers. these are likely central fevers as the patient has no white count. blood cultures have remained no growth from . he has been on the antibiotics since the 20th. his u/a was negative. his chest x-ray was negative. he showed no other signs or symptoms of infection. 7. prophylaxis: the patient was maintained on subcutaneous heparin b.i.d. while he was not ambulating. he was also maintained on a ppi and bowel regimen. 8. code: the patient is full code. condition on discharge: good. pain well controlled. the patient was ambulating but requires further physical therapy. neurological examination stable. discharge status: the patient is to be discharged to a rehabilitation facility yet to be identified for continued physical therapy. discharge medications: 1. heparin 5,000 units subcutaneously b.i.d. until the patient is ambulating regularly. 2. oxycodone acetaminophen 5/325 one to two tablets p.o. q. four to six hours p.r.n. pain. 3. colace 100 mg p.o. b.i.d. 4. protonix 40 mg p.o. q.d. 5. tylenol 325 to 650 mg p.o. q. four to six hours p.r.n. 6. dilantin 300 mg p.o. t.i.d. 7. acyclovir 800 mg iv q. eight hours until hsv pcr negative. 8. vancomycin 1 gram iv q. 12 hours times ten days. 9. ceftriaxone 2 grams iv q. 24 hours times ten days. follow-up: 1. the patient is to follow-up with his primary care physician in one to two weeks. 2. the patient is to follow-up with orthopedics for removal of his cast as instructed. 3. the patient is to follow-up with neurology for continued management of his dilantin as instructed.
