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 38-year-old gentleman who fell at work after having a generalized seizure. he fell from the standing position. he was transferred to where a head ct showed a left subdural hematoma and left fronto-temporal interparenchymal contusion with a small amount of subarachnoid hemorrhage. the patient has a significant history of etoh abuse in the past. the patient was med-flighted to for further treatment. on arrival, pupils were equal, round and reactive to light. he had positive corneal reflexes and positive gag reflex but continued to be paralyzed. he had a right arm hematoma. he had a repeat head ct which showed an increase in the subdural hematoma and parenchymal blood with a temporo-parietal contusion. the patient was admitted to the surgical intensive care unit for close monitoring. hospital course: on , the patient had a repeat head ct which showed evolution of the left fronto-temporal contusion, overall mass effect and not significantly changed. moving all four extremities. the right arm was moving less than the left arm, and there was a question of a generalized seizure. the patient was on cpap with pressure support on the ventilator and being weaned. the patient spiked a temperature to 101.8 and sputum cultures were sent. the patient was extubated on and tolerated it until when he required reintubation for an obstruction of his airway and secretions. the patient also had a lumbar puncture done on for a temperature of 104 to rule out meningitis from attempted ventriculostomy drain placement. cultures came back negative. the patient did have positive blood cultures for gram negative rods and was on a 14 day course of vancomycin. the patient had an eeg which showed no seizure activity and continued to improve neurologically until when his mental status deteriorated. head ct showed an increase in swelling. he had a ventriculostomy drain placed at that time. neurologically, he slowly improved after ventriculostomy drain placement. the patient was also started on mannitol for brain edema. the patient had a repeat head ct on which showed increase in midline shift, left temporal edema and slight increase in ventricular size with ventricular drain placed. continued on mannitol and clinically stable. continued with strict fluid restriction. on , the patient had a repeat head ct which showed an increase in size of the left subdural hematoma. the patient was taken to the operating room and had a bur hole drainage of the left subdural hematoma without intraoperative complications. postoperatively, the patient was attending but not following commands, opening his eyes purposefully and moving on the left. pupils were 3, down to 2.5 mm and brisk. withdrawing all extremities to pain. he was seen by the hematology service for an increasing platelet count. the patient's thrombocytosis was thought to be secondary to inflammation with no immediate treatment required. the patient's platelet count was as high as 1222. currently, it is 704. on , the patient was opening his eyes. gaze was conjugate. pupils were 4, down to 3 mm and brisk. he was withdrawing the left side greater than the right. not following commands. ct showed stable size of the residual subdural fluid and a small amount of blood in the track from the ventriculostomy drain. on , the patient's eyes would open spontaneously. he was moving his left side spontaneously and withdrawing the right upper extremity. not following commands. withdrawing is slower. ct scan showed mild decrease in brain edema. mannitol was weaned. the patient was awaiting peg and trach placement. on , the patient self-extubated. the patient tolerated extubation. he was awake, alert and following simple commands. perseverating on motor exam. holds arms up off the bed. right side weaker than the left. the patient had a speech and swallowing evaluation which he passed. he was transferred to the regular floor on . he remained neurologically awake and alert, moving all extremities, confused and agitated at times with severe receptive aphasia, but slowly improving. he was seen by physical therapy and occupational therapy and found to require rehabilitation. he continues on vancomycin currently at 750 mg intravenously q12 hours for gram negative sepsis, until . medications at discharge: 1. captopril 12.5 mg n.g. t.i.d. 2. heparin 5000 units subcutaneously b.i.d. 3. lopressor 150 mg p.o. t.i.d., hold for systolic blood pressure of less than 110 and heart rate less than 55. 4. multivitamin 1 p.o. q day. 5. magnesium oxide 400 mg p.o. q day. the patient's condition was stable at the time of discharge. he will follow up with dr. in one month with repeat head ct. , m.d.
