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 a 76 year old caucasian woman with a past medical history significant for pneumonia and diverticulitis, who, on the evening of admission, was at home and was noted by her husband to call out in pain, complaining of the acute onset of a headache. soon thereafter she was noted to lose consciousness and was unresponsive. paramedics were called to the scene. upon arrival of paramedics, patient was noted to have a weak and thready pulse and cpr was administered and patient was intubated. patient was transported to for evaluation. at head ct was performed which showed significant subarachnoid hemorrhage in the suprasellar cistern, the perimesencephalic cisterns as well as intraventricular hemorrhage in the frontal horns and within the third ventricle. diffuse cerebral edema was also noted. patient was then transported to for further care. past medical history: pneumonia. diverticulitis. dehydration. medications: none. allergies: aspirin intolerance. social history: lives with husband. smoking status unknown. physical examination: temperature 33.8 degrees, blood pressure 91 to 121 systolic over 44 to 76 diastolic, heart rate 116 to 122. patient was intubated, 100% fio2. on general examination, thin, caucasian woman laying in bed, intubated, unresponsive. heent: no evidence of head trauma. pupils fixed, dilated, approximately 7 mm midposition. oropharynx clear. heart had regular rhythm and was tachycardiac without murmurs, gallops or rubs. lungs were clear to auscultation bilaterally. abdomen was nontender, nondistended with decreased bowel sounds throughout. extremities had good dorsalis pedis pulses as well as good radial pulses bilaterally. there was no cyanosis, clubbing or edema. on neurological examination she was unresponsive to noxious stimuli. pupils were fixed and dilated. she had no gag or cough reflexes. corneal reflex was absent. ocular cephalics showed no evidence of vestibular function. .................... were performed which showed no nystagmus. reflexes were 1+ throughout symmetrically. musculoskeletal examination showed no evidence of trauma, ecchymosis or abrasions. laboratory data: ekg showed normal intervals, normal axis with a mildly prolonged qt interval and mild st elevations in 1, avl, v2 and v5 through v6. white blood count was 33.7, hematocrit 40.8, platelets 370. ck was 258. sodium 138, potassium 3.3, chloride 106, bicarb 16, bun 12, creatinine 0.7, glucose 217. urinalysis showed 6 to 10 red blood cells, few bacteria. abg showed ph of 7.50, pco2 21, po2 655. hospital course: the patient was admitted to the intensive care unit. cardiology was consulted initially because of concern over st elevations apparent on her admission ekg. cardiology consult felt that the diffuse nonspecific changes were most likely due to cerebral catastrophe. neurosurgery was also consulted and felt that patient was clearly without brainstem reflexes with an extremely poor prognosis. the neurosurgery service did not recommend further intervention. patient was rewarmed to a temperature of 97 degrees. central access was obtained through the left femoral vein. the right femoral vein was accessed with an arterial catheter for continuous blood pressure monitoring. patient continued to have absent brainstem reflexes even after rewarming and volume resuscitation. patient then began to exhibit increasing metabolic acidosis by her arterial blood gas and this precluded the diagnosis of brain death. she was discussed with the transplant team coordinator who was in the intensive care unit and evaluated the patient. it was felt that in the setting of worsening metabolic acidosis, there was little benefit to be gained through further attempts to salvage the organs for harvest. the situation was discussed with the family in detail and the family was aware of the prognosis. family returned in the morning and patient's ventilatory support was removed and pressors were stopped. patient expired quickly after removal of the endotracheal tube. the patient was pronounced dead at 11:27 a.m. on . the medical examiner was notified and declined autopsy. , m.d. dictated by: medquist36 d: 13:50 t: 09:02 job#: procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified diagnoses: subarachnoid hemorrhage compression of brain acute myocardial infarction of unspecified site, initial episode of care 

Answer: The patient is high likely exposed to
