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 a 67-year-old woman with a history of a prior mca stroke on the left, aphasia and right-sided weakness, who lives alone and was found by her neighbor on the day of admission seizing. she apparently had two falls this month, one of which was the week prior to presentation. the details of the fall are not available but her health care proxy states that she saw ms. last thursday and also spoke to her over the weekend and she seemed find. on the day of presentation she told a neighbor that there was an unusual sensation in her right arm but otherwise she was feeling okay. per ems notes she was nauseated with some vomiting today on arrival. later the neighbor checked in on ms. and found her convulsing. ems was called and they found her to have generalized convulsions while sitting in an armchair. she was intubated in the field. she received valium 10 mg x 1 and then again 5 mg. in the emergency room she continued to have focal seizures involving the right arm and was given a total of 14 mg of ativan as well as a dilantin load. past medical history: 1. left mca stroke with right hemiplegia, complete left carotid occlusion with 80% right carotid occlusion. 2. vulvar carcinoma. 3. hypertension. 4. hypercholesterolemia. medications: 1. prednisolone ac eyedrops. 2. xalatan eyedrops. 3. cosopt eyedrops. 4. ambien 5 mg at bedtime as needed. 5. aspirin 325 mg p.o. by mouth. 6. atenolol 25 mg p.o. q. day. 7. lipitor 10 mg p.o. q.d. 8. hydrochlorothiazide 25 mg p.o. q. day. 9. k-dur 20 meq p.o. q. day. 10. valsartan 80 mg p.o. q. day. social history: she lives alone and drives. there is some history of alcohol use. physical examination: temperature 97.8, blood pressure 117/68, heart rate 82, 99% on a ventilator. general: she appeared her stated age lying in bed intubated with occasional rhythmic flexion of the right elbow and fingers. head/neck: normocephalic, atraumatic, sclerae were white. neck was supple. lungs: vented and sounded clear. cardiovascular: some distant sounds. abdomen: soft, nontender, nondistended. extremities: warm without clubbing or edema. there were multiple small bruises over her right shoulder and breast. they were of different ages. neurologic: intubated, sedated, not following commands or responding to voice. her face was grossly symmetric. eyes were open with a gaze deviation to the right, no blink to threat with the right eye. left eye was opacified from a corneal scar. funduscopic examination was not possible. right pupil was reactive 3.5 to 3. motor: there were rhythmic choreic motions in her right elbow and arms that were intermittent. she withdrew to pain in the right arm and leg more than the left. reflexes showed symmetric throughout but there were no knee or ankle reflexes. the plantar reflexes were up on the left and mute on the right. there was no ankle clonus. laboratory data: glucose 142, chloride 99, anion gap 24, toxicology screen was negative. white blood cells 13.5. head ct showed a large left mca infarction which was old. there was no bleed or mass effect. chest x-ray appeared normal. ecg showed left bundle branch block and a rate of 84. hospital course: the following course is as noted by the stroke/neurology service, dr. . ms. presents with a new seizure, likely secondary to a substrate from her old left mca stroke. we continued dilantin at 300 mg q. day. during the dilantin load initially in the emergency room she dropped her blood pressure and this was initially felt to be secondary to dilantin iv and therefore she was continued on some pressor support initially. however, over the next several days she continued to require blood pressure support with an elevated white count and further examination also revealed a right-sided hemiparesis which was felt to be secondary to paralysis. ms. was intermittently in and out of left bundle branch block, with a systolic murmur. further evaluation through review of the charts from several years earlier showed that indeed the systolic murmur and intermittent left bundle branch block were old. in addition, she has undergone left cea in with resultant right arm weakness. she continued to require pressor support and did not improve clinically and therefore we began to search for a source of infection, sending for a chest x-ray, urinalysis, and blood cultures. we also evaluated with an mr imaging study of the brain which showed her old left mca infarct but nothing acutely new. her history includes a left cea in and despite this, she suffered a left mca ischemic stroke in which left her with some right-sided weakness and aphasia. further history indicates that at baseline she lives by herself and drives a car. she is aphasic with little verbal output but has some understanding of single thoughts and concepts and she has problems with complex sentences. she had been well until when she had some right arm sensation changes as noted above and found to have a generalized convulsion with some focal onset. she was loaded on dilantin as noted and became hypotensive. a lumbar puncture at that time was unrevealing with a white cell count of 4, red cells of 0, and protein of 65. as indicated above, the initial work-up including blood culture, urine and cerebrospinal fluid studies were not consistent with an acute infection and yet she continued to require pressor support and subsequently developed a temperature up to 101.2. further evaluation with arterial line and peripheral line cultures showed gram-positive cocci. urine and sputum later grew gram-negative rods. levofloxacin and vancomycin were started and she was weaned off the neo drip at the same time she was extubated. her right hemiparesis improved. the mr study showed that the right ica was stenotic up to 60%. as she continued clinically she was transferred to the floor and evaluated for rehabilitation needs. she was sent to the hospital. at the time of transfer she was clinically stable and appropriate for transfer. outstanding issues for her include further discussion with her health care proxy and her about the possibility of intervention in the right carotid as it remains the only source of perfusion to the brain. discharge status: discharged to rehabilitation. condition on discharge: improved. discharge diagnosis: new seizure disorder secondary to old stroke. secondary diagnoses: 1. left mca ischemic infarct. 2. left cea but with no flow. 3. right carotid stenosis of at least 60%. discharge medications: 1. dilantin 110 mg p.o. t.i.d. 2. vancomycin 1,000 mg b.i.d. for nine days. 3. levofloxacin 500 mg p.o. q. day for nine days. 4. folate 1 mg p.o. q.d. 5. multivitamin q.d. 6. thiamine q.d. 7. prevacid 30 mg q.d. follow up: ms. will follow up with her primary care physician and dr. . note: the above discharge summary is a redictation. the initial discharge summary sent with her to the rehabilitation seems to have been lost in the records. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified spinal tap incision of lung
