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: tetanus toxoid / penicillins / attending: chief complaint: r sided hemiparesis major surgical or invasive procedure: none history of present illness: 79yo rh m who was last known well at his nursing home around noon-ish, when he ate lunch. he then had the abrupt onset of right facial droop and right arm weakness and has been unable to speak since. by report, he was hypoxic in the 70s and hypotensive; on arrival, bp was 90s/50s and he was placed on a nrb. he was recently discharged on coumadin, since he has an aortic valve. his nh documentation shows last inr on of 1.5. he has been treated recently for c diff, with last day of flagyl due tomorrow. past medical history: - seizure disorder on dilantin; unclear etiology - rheumatic heart disease, s/p mvr ~ - cad, s/p cabg - as s/p avr - htn - dyslipidemia - spinal stenosis - status post c1-c5 anterior fusion - status post l2-5 decompressive surgery - status post c2-4 posterior fusion - oa s/p left knee arthroplasty in - neuropathy - b12 deficiency - hospitalized at for food aspiration and esophageal impaction, aspiration pna, and dilation of esophageal ring - bph s/p turp - chronic bilateral carpal tunnel syndrome social history: lived at home w/ wife but currently at for rehab. no hx of tobacco, etoh or drug abuse. however,most recently in nursing home. family history: no family history of seizures physical exam: pe vs 99.6 89/50-150s/60s after fluid bolus 12 100% gen awake, cooperative, nad heent nc/at, no scleral icterus noted, mmm, no lesions noted in oropharynx neck supple, no carotid bruits appreciated. no nuchal rigidity lungs cta bilaterally cv rrr, nl s1s2, no m/r/g noted abd soft, nt/nd, normoactive bowel sounds, no masses or organomegaly noted ext no c/c/e b/l skin no rashes or lesions noted neuro ms eyes closed, rouses to verbal stimuli. does not follow commands or speak. drowsy. cn cn i: not tested cn ii: no blink to threat on the right. pupils 3->2 b/l. cn iii, iv, vi: eyes deviated to the left, full eom to oculocephalics cn v: b/l corneals cn vii: r facial droop cn viii: opens eyes to voice cn ix, x: palate rises symmetrically, but choking on saliva cn : unable to assess cn xii: unable to assess motor r arm flaccid. moves left arm purposefully to pain. the right externally rotates to noxious stimuli. b/l triple flexion in the legs sensory grimaces to noxious stimuli throughout reflexes br tri pat ach toes l 2 2 2 1 0 up r 0 0 0 1 0 up coordination unable to assess gait deferred code stroke scale: neurologic (nihss): 22 1a. loc: 2 1b. loc questions: 2 1c. loc commands: 2 2. best gaze: 2 3. visual: 2 4. facial palsy: 3 5a. left arm: no drift (0) 5b. right arm: 4 6a. left leg: no drift (0) 6b. right leg: no drift (0) 7. limb ataxia: x 8. sensory: no sensory loss bilaterally (0) 9. language: 3 10. dysarthria: 2 11. extinction/inattention: none (0) pertinent results: ct brain perfusion 5:30 pm cta head w&w/o c & recons;

Answer: The patient is high likely exposed to
