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 an 82 year old woman with parkinson's disease and history of previous stroke who recently suffered a left middle cerebral artery stroke, status post tpa treatment, who is now being transferred to the neurology floor. her recent history includes four days of upper respiratory infection with signs and symptoms including nonproductive cough and fatigue. on , the patient was at her senior center and had an episode of right knee weakness which was initially attributed to her arthritis. however, by 4:00 p.m. that day, her knee collapsed and she was quite weak; her daughter took her home but she remained weak. during this time, she continued to be oriented and had no other problems. she was taken to the where a diagnosis of right lower lobe pneumonia was made and levofloxacin started in the emergency department at that time. however, on transfer to the floor, she was noted to have a sudden onset of right sided arm and leg weakness and she was unable to articulate but was still able to nod appropriately to questions. head ct showed atrophy and the patient was transferred to for acute management of stroke. the patient underwent mr imaging study which showed decrease water diffusion in the distribution of the left middle cerebral artery without significant mass effect and she received tpa at 5:10 a.m. post tpa, she has been stable but clinically has not shown any appreciable improvement. repeat ct is without bleed or evidence of increased intracranial pressure. doppler without evidence of reflow. at baseline, the patient lives with her daughter and is quite functional, able to house chores and feed herself. per her daughter, she had a nonproductive cough and fatigue for four days with difficulty feeding herself the day prior to presentation to . no fever, chills, chest pain, palpitations, headache, loss of consciousness or focal weakness except for the right knee weakness; she has had urinary incontinence for the last six months. both the patient's daughter and son-in-law were ill with the flu in the days prior to presentation. past medical history: 1. sepsis with pulmonary embolism some eleven years ago. 2. parkinson's disease diagnosed ten years ago. 3. macular degeneration. 4. stroke in the past with diagnosis by mr in but without residual deficits. 5. history of dilated ventricles first seen in , but repeat mr in , was unchanged. 6. recently diagnosed b12 deficiency. allergies: sulfa allergy as a child. medications on admission: 1. carbidopa 25/100 t.i.d. 2. requip 0.25 mg t.i.d. (delusions at high doses). 3. amantadine 100 mg q.d. 4. detrol 2 mg b.i.d. p.r.n. 5. dulcolax p.r.n. 6. b12 one q.week for four weeks which has been completed. social history: the patient lives with her daughter and son-in-law in . she was a homemaker without history of ethanol or tobacco use. her neurologist is dr. at . primary care physician is . . physical examination: temperature maximum 100.2, temperature current 98.8, heart rate 79, blood pressure 165/71, oxygen saturation 100% on two liters. general: elderly woman in no acute distress. head and neck: normocephalic, supple, no lymphadenopathy, no bruits. cardiovascular: regular rhythm, normal rate. pulmonary: clear to auscultation except some decreased breath sounds on the right. abdomen: positive bowel sounds, soft, nontender, nondistended. extremities: positive pulses. neurologic: arousible but sleepy. she will close eyes to command but not much else. nonverbal. cranial nerves: the pupils are equal, round, and reactive to light and accommodation, 3.0 millimeters going down to 2.0 millimeters. extraocular movements are full. blinks to threat. closes eyes on command. right facial droop. motor: bulk is normal. tone is somewhat flaccid on the right. the right arm and leg withdraw to pain. spontaneous left arm movement. resting tremor on the left hand. right arm and leg strength likely full. reflexes are 2+ in the biceps bilaterally, trace in the triceps bilaterally, brachial radialis 1+ bilaterally, patella 2+ on the left and 3+ on the right, no gastrocnemius. toes are downgoing on the left and upgoing on the right. grasp reflex present on the left hand. laboratory data: white blood cell count 10.0, hematocrit 30.8, platelets 207,000. sodium 138, potassium 3.9, chloride 103, bicarbonate 22, blood urea nitrogen 16, creatinine 0.8, and glucose 118. magnesium 2.0, calcium 8.1, phosphorus 3.1. electrocardiogram: normal sinus rhythm at 70, q wave in lead iii, v1 and t wave inversion in ii, iii, avf and v1 through v5. no acute st changes. mr imaging: decreased diffusion in the left middle cerebral artery distribution, no mass defect. ct scan post tpa without bleed, no mass effect. chest x-ray: from the outside hospital revealed a slight right middle lobe opacity, no cardiomegaly and no effusion. hospital course: as indicated above, the patient was admitted after her new onset stroke and she received tpa intravenously but there was no reflow on post tpa studies. the patient clinically remained stable, however, did not have any significant meaningful clinical improvement over the course of the hospitalization. she was initially responsive to noxious stimuli with appropriate withdrawal. she would close her eyes to command. however, on the day of this dictation, she was no longer responsive even to midline command of eye opening and closure. she appeared comfortable. after further discussion with her family, both son and daughter, a decision was made to focus on her comfort and therefore, the patient was made comfort measures and referred to hospice. she is currently clinically stable and appropriate for transfer to a hospice facility. we anticipate that the patient will be given morphine and ativan as needed to keep her comfortable although we note that she is currently very comfortable both from a respiratory perspective and pain perspective without ativan or morphine. condition on discharge: not improved. discharge status: discharged to hospice facility. discharge diagnoses: 1. left middle cerebral artery stroke without clinical improvement despite tpa. 2. currently comfort measures and being transferred to a hospice facility. medications on discharge: morphine and ativan as needed for comfort. , m.d. dictated by: medquist36 procedure: injection or infusion of thrombolytic agent diagnoses: paralysis agitans cerebral artery occlusion, unspecified with cerebral infarction 

Answer: The patient is high likely exposed to
