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: this is an 85-year-old male who was transferred from hospital. he has a past medical history of advancing alzheimer's. his baseline mental status is that he is confused and not conversational. he also has a past medical history of coronary artery disease, who was in his usual state of health until when his daughter tried to help him out of a chair, and he could not get up. normally he is able to ambulate without assistance. the patient's daughter called 911, and the patient was brought to the hospital emergency room. the patient was admitted, and later cat scan of the head showed acute frontal parietal hemorrhage with extension to the ventricles. the patient was transferred to for further management. the patient was confused but alert and talkative, moving all extremities on arrival. pupils were reactive and equal bilaterally. horizontal gaze was intact bilaterally. corneal reflexes were intact bilaterally. face was symmetric. the patient had increased tone in the lower extremities bilaterally, which was greater than upper extremities, but he was able to move all extremities well. he localized to pain. head ct showed right frontal parietal lobe hemorrhage with extension into the right lateral ventricle. the patient was admitted to the trauma sicu for blood pressure monitoring. the patient's aspirin was discontinued. the patient was placed on a 1 l fluid restriction. an ng tube was placed for medication and nutrition. bedside swallow done on , revealed the patient not able to tolerate p.o. tube feeds were started. the patient's neurological status improved slightly, although the patient remained disoriented, confused, was easily agitated. the patient was transferred to the floor on . on , the patient became more lethargic and was not following commands. he had decreased verbal output. head ct was repeated with small increase in the size of intracerebral hemorrhage. there was no significant change in ventricle size. fever work-up was sent. chest x-ray was negative. arterial blood gas was within normal limits. cultures were negative. the patient's vital signs remained stable. the patient remained afebrile. the patient's prognosis and current condition were discussed at length with the family, who decided to make the patient dnr status. gi consult was called for peg placement. the patient's neurological status improved slightly over the course of the next few days. the patient received peg tube on without complication. the patient was scheduled for rehabilitation placement on . discharge medications: the patient will be discharged to rehabilitation on sliding scale insulin coverage, metoprolol 50 mg p.o. b.i.d., atorvastatin 10 mg p.o. q.d., enalapril 20 mg p.o. q.d., acetaminophen 325-650 mg p.o. q.4-6 hours p.r.n., dorzolamide 2%, timolol 0.5% ophthalmic 1 drop o.u. b.i.d., brimonidine tartrate 0.15% ophthalmic 1 drop o.u. q.8 hours, bisacodyl 10 mg p.o. p.r. q.d. p.r.n., milk of magnesia 30 ml p.o. q.6 hours p.r.n. discharge instructions: the patient has a foley catheter in place. the patient is currently on a 1000 ml fluid restriction. tube feed goal is impact 75 cc/hr. condition on discharge: the patient is essentially neurologically unchanged at the time of discharge. follow-up: the patient is to follow-up with dr. in one month with repeat head ct prior to appointment. , m.d. dictated by: medquist36 procedure: other endoscopy of small intestine enteral infusion of concentrated nutritional substances percutaneous [endoscopic] gastrostomy [peg] diagnoses: congestive heart failure, unspecified aortocoronary bypass status intracerebral hemorrhage alzheimer's disease dementia in conditions classified elsewhere without behavioral disturbance 

Answer: The patient is high likely exposed to
