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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: s/p ?fall major surgical or invasive procedure: none history of present illness: 45yo m with extensive history of alcohol abuse was found unconscious at the bottom of 25 stairs. pt sustained apporximately 500cc of blood loss at the scene and was arousable only to painful stimuli. he was transported to for further care. gcs 6 upon arrival to ed, smells of etoh. he was intubated and his fast was negative. past medical history: alcohol abuse hypertension social history: h/o history etoh abuse for many years intermittently homeless family history: noncontributory physical exam: upon admission: t:98.7 bp: 149/102 hr:89 r20 o2sats96% gen: wd/wn, comfortable, nad. heent: pupils: perrl eoms: does not track examiner, barely keeping eyes open. neck: supple. extrem: warm and well-perfused. neuro: mental status: sleepy, appears sedated, can barely keep eyes open, but follows most commands. orientation: not oriented though sedated language: grunts and moans, no normal verbal interaction. cranial nerves: ii: pupils equally round and reactive to light, 5 to 2 mm bilaterally. iii, iv, vi: difficult to assess, not tracking well, heavily sedated. v, vii: facial strength and sensation not assesed. viii: hearing intact to voice. ix, x: palatal elevation symmetrical. : sternocleidomastoid and trapezius normal bilaterally. xii: tongue midline without fasciculations. motor: normal bulk and tone bilaterally. d grip ip incomplete exam due to mental status r 3 4+ 5 l 5 5 5 unable to assess pronator drift sensation: intact to light touch bilaterally. reflexes: pa right 2 left 2 toes downgoing bilaterally coordination: normal on finger-nose-finger left side, right arm sluggish to bring to nose. pertinent results: 03:00am blood wbc-15.5* rbc-5.47 hgb-16.9 hct-46.1 mcv-84 mch-31.0 mchc-36.8* rdw-13.7 plt ct-339 03:00am blood pt-13.6* ptt-20.8* inr(pt)-1.2* 03:00am blood fibrino-444* 06:30pm blood glucose-133* urean-14 creat-1.0 na-141 k-3.9 cl-102 hco3-28 angap-15 02:28am blood alt-24 ast-37 ld(ldh)-332* alkphos-61 amylase-113* totbili-1.9* 02:28am blood lipase-35 06:30pm blood calcium-8.7 phos-3.2 mg-1.8 04:05am blood ammonia-41 02:28am blood tsh-1.2 03:00am blood asa-neg ethanol-170* acetmnp-neg bnzodzp-neg barbitr-neg tricycl-neg 09:43am blood type-art temp-37.1 peep-5 fio2-50 po2-201* pco2-40 ph-7.42 caltco2-27 base xs-1 intubat-intubated 03:27am blood glucose-149* lactate-6.6* na-144 k-3.6 cl-101 calhco3-21 03:27am blood hgb-18.6* calchct-56 ct head w/o contrast: extensive soft tissue swelling, with a right frontal laceration. no acute intracranial injury identified. ct head w/o contrast: 1. no evidence of acute intracranial abnormalities. 2. interval accumulation of fluid in the right sphenoid sinus with diffuse mucosal thickening throughout the other paranasal sinuses, which i commonly seen in intubated patients. eeg: abnormal portable eeg due to the very low voltage background with usually slower frequencies as the predominant rhythm but with some widespread faster activity superimposed, and all without a typical antero-posterior gradient. these findings suggest a widespread encephalopathy, and the faster frequencies and low voltage raise the possibility of medication as a cause of that encephalopathy. nevertheless, there were no areas of prominent focal slowing (although encephalopathies may obscure focal findings), and there were no epileptiform features. ct head w/o contrast: no evidence for acute intracranial abnormality. mr head w/o contrast: 1. small bilateral frontal subdural fluid collections, likely hygromas. 2. no abnormal signal intensity or diffusion abnormalities detected in the brain to suggest hemorrhage, infarction, or other neuronal injury. ct head w/o contrast: 1. no evidence of fracture, hemorrhage, or edema. 2. no significant change since three days prior. 3. right frontal soft tissue swelling. brief hospital course: he was admitted to the trauma service. initial toxicology screens were only positive for etoh. neurosurgery and neurology were consulted. imaging studies of the head were negative except for extensive soft-tissue swelling. he remained minimally responsive and dysarthric during the first several days of admission. on he was noted to have improved eye opening and some following of commands, however he was noted to have decerebrate posturing in his upper extremities. repeat head ct did not reveal any changes. subsequent eeg showed widespread encephalopathy and mri did not show any acute changes. he was eventually transferred to the floor but remained dysarthric and could occasionally follow commands. he sustained several falls while on the regular nursing unit; no significant injuries were sustained. on repeat head ct there was a slight increase in right frontal soft-tissue swelling. over the course of his hospital stay his mental status improved significantly. occupational therapy worked with him for cognitive therapy. he was also evaluated by physical therapy because of poor balance; this did eventually improve as well. social work was closely involved with patient throughout his stay. he was referred to a sober house near his family. discharge medications: 1. folic acid 1 mg tablet sig: one (1) tablet po daily (daily). 2. thiamine hcl 100 mg tablet sig: one (1) tablet po daily (daily). 3. fexofenadine 60 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* discharge disposition: home discharge diagnosis: s/p ?fall traumatic brain injury without brain hemorrhage right frontal laceration discharge condition: hemodynamically stable, tolerating a regular diet, pain adequately controlled. discharge instructions: avoid any alcohol or illicit drug use. because of your fall you did sustain an mild traumatic head injury; it is not uncommon to experience periods of dizziness, with headchaes, you may even become forgetful at times. sleep disturbacnes can sometimes occur. these symptoms usually do get better over sevral weeks to several months. return to the emergecny room if you develop headaches that won't go away, changes in your vision, seizure activity, fevers, shortness of breath, nausea, vomitng, diarrhea and/or any other symptoms that are concerning to you. followup instructions: follow up as an outpatient in trauma clinic for any concerns related to your hospital stay. call if you need an appointment. md, procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube enteral infusion of concentrated nutritional substances closure of skin and subcutaneous tissue of other sites diagnoses: unspecified essential hypertension open wound of forehead, without mention of complication accidental fall on or from other stairs or steps encephalopathy, unspecified urinary incontinence, unspecified closed fracture of multiple ribs, unspecified other and unspecified alcohol dependence, continuous intracranial injury of other and unspecified nature without mention of open intracranial wound, with loss of consciousness of unspecified duration 

Answer: The patient is high likely exposed to
