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: no drug allergy information on file attending: chief complaint: nausea, vomiting, gtc major surgical or invasive procedure: intra-arterial tpa history of present illness: pt. is a 68 year old with a recent l cerebellar infarct and l vert occlusion who presented to hospital earlier today with nausea and dry heaves, and seized for > 30 minutes while being worked up, who is transferred here for neuro eval. wife reports that he complained of nausea and dizziness this afternoon. these were the same symptoms he had when he was diagnosed with a stroke on , and he asked to be taken to the hospital. he arrived there at 3:15. he did not complain of, and she did not notice, any weakness, numbness, slurred speech, facial droop, dysphagia, vision changes or vision loss. she reports that since the stroke on he has had some double vision, but that this was not any worse today. he's also had some balance problems, with a tendency to fall to the left, but this has been improving lately, and earlier today he actually walked without a walker for the first time since the stroke. he initially had some l sided neglect, but this improved while he was in the hospital and has not recurred. he never had any weakness or facial droop that they remember. initially at osh ed, they record that pt's speech was clear and coherent, he moved all extremities, and had no facial assymetry. they did not find any focal deficits. around 6:00 he complained of some tingling in his fingertips on the left, which was a new symptom for him. he vomited once after that (time not documented) a head ct was performed and showed no mass, no mass effect, no ich, but evidence of a r bg lacune, low attenuation in the l occipital lobe concerning for subacute infarction, and small vessel ischemic changes. at 20:24 he became unresponsive and started having a generalized tonic clonic seizure. he received ativan 4 mg, then dilantin 1000 mg, and stopped seizing at 21:01 finally. he was intubated then, and then at 21:15 had another 5 minute seizure that aborted with another 2 mg ativan. he was transferred here for further care. past medical history: l cerebellar infarct and l vert occlusion- diagnosed at nyu (was in on vacation at the time), started on fragmin and coumadin, with asa and plavix to "bridge" him until coumadin therapeutic. at coumadin became therapeutic and fragmin was stopped, and on the plavix was stopped as well. htn borderline hyperlipidemia social history: self employed insurance , no tobacco, occasional glass of wine. married, lives with wife. daughter is a sicu nurse here at . family history: no stroke, no mi, cousin with dm physical exam: bp- 103/65 hr- 108 rr- 16 o2sat- 100% on ac gen: lying in bed, intubated heent: nc/at, moist oral mucosa neck: supple, no carotid bruit cv: rrr, nl s1 and s2, no murmurs/gallops/rubs lung: clear to auscultation bilaterally abd: +bs soft, nontender ext: no edema neurologic examination: mental status: intubated, sedated, does not open eyes to voice or sternal rub cranial nerves: pupils 5 mm, nr bilaterally. + corneals bilaterally, + gag on ett. no eom with dolls. motor/sensory: normal bulk bilaterally. tone normal. no observed myoclonus or tremor. withdraws both arms on the plane of the bed with nailbed pressure. withdraws r leg minimally with pain, no movement lle with pain reflexes: trace throughout. toes mute bilaterally coordination, gait: not assessed pertinent results: 143 102 18 ------------< 141 4.3 28 1.0 serum asa, etoh, acetmnphn, benzo, barb, tricyc negative urine benzos, barbs, opiates, cocaine, amphet, mthdne negative wbc 8.1 hgb 15.8 plt 288 hct 44.1 mcv 90 n:82.9 band:0 l:15.2 m:1.2 e:0.1 bas:0.5 plt-est: normal pt: 13.1 ptt: 24.6 inr: 1.1 imaging ct, cta head, wet read: acute to subacute lt pca distrib cva. take off of lt vert not identified and proximal portions display several regions of marked atherosclerosis/narrowing. distal basilar displays abrupt cutoff with no filling of the proximal pca's bilaterally with partial reconstit of flow from the rt mca to the rt pca. left pca is very attenuated. right vert terminates in rt pica. brief hospital course: this is a 68 yo man with left cerebellar stroke and left vertebral occlusion on . now presented with new onset of nausea, dizziness as well as two generalized seizures. imaging showed new left pca stroke; cta revealed occluded left vert and clot in proximal basilar artery and distal basilar occlusion. patient was started on heparin initially. he had pupils that were 5mm and reactive to light and he had all brainstem reflexes. about hours later, he developed fixed pupils and had no left corneal reflex. he also had decreased and decerebrate movements to nailbed pressure. a repeat hct and cta showed the clot in the proximal basilar artery and an occlusion of the most distal basilar artery. he was taking to the angio suite. angio showed the occluded left vertebral artery and a hypoplastic right vertebral artery. it was attempted to canulize the left vertebral artery, but this is unsuccessful. then a selective catheter was placed into the right vertebral artery and the patient was given 8mg of tpa into the distal basilar artery beyond the proximal clot. after extensive discussion with members of the patient's family including his wife (health care proxy). his living will indicated that he would not want life prolonging supportive therapy. in view of his significant neurologic deficits his family decided to make the patient cmo. the family requested the organ bank be contact. the patient did not exhibit spontaneous respirations upon removal of the ventilator. he went into asystole and expired. his organs were harvested by neob for transplant in accordance with his family's wishes. medications on admission: lisinopril 10 mg qd lipitor 80 mg qd- stopped because of muscle pain in legs asa 81 coumadin 5 mg qhs (inr therapeutic on d/c from on per wife) atenolol 25 mg qd mvi discharge medications: n/a discharge disposition: expired discharge diagnosis: pt expired discharge condition: na discharge instructions: na followup instructions: na md, procedure: injection or infusion of thrombolytic agent arteriography of cerebral arteries diagnoses: unspecified essential hypertension occlusion and stenosis of multiple and bilateral precerebral arteries with cerebral infarction acute respiratory failure 

Answer: The patient is high likely exposed to
