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 72-year-old woman with a sudden onset of severe headache on the morning of admission. she was sent to an outside hospital and had a head ct which showed subarachnoid hemorrhage. she had but dizzy and nauseous and transferred to for further management. past medical history: cataracts, bilateral total knee replacement, tah bso, hypertension, rheumatoid arthritis. physical examination: her bp was 115/palp, sats 99, heart of headache and neck stiffness. she was alert and oriented times three, responsive. her sensory motor was intact. both upper and lower extremities showed pupils were equal, round and reactive to light, eoms full. ct at the outside hospital showed positive subarachnoid hemorrhage, +- hydrocephalus. laboratory data: on admission, white count was 11.7, hematocrit 39.5, platelet count 287,000, sodium 134, potassium 3.4, chloride 103, co2 23, bun 11, creatinine .7. hospital course: the patient was admitted to the neuro intensive care unit for close monitoring. the patient underwent arteriogram and coiling of the right p2 branch of the posterior cerebral artery without complication. the patient was continued to be monitored in the surgical intensive care unit with iv fluids going at 125/hour. he was awake, alert, moving all four extremities, oriented times two with good anti-gravity strength. postoperative day #1 her mental status was somewhat depressed, she was somewhat lethargic, she had a repeat head ct which showed evidence of hydrocephalus. she therefore had a vent drain placed on without complication. the patient remained in the intensive care unit for observation for evidence of vasospasm. on the patient complained of severe back pain radiating down both her legs. she was started on iv decadron with good relief. she was seen by rheumatology service as well who recommended x-ray films of the hip and pelvis which were unremarkable and continued on her prednisone for her rheumatoid arthritis. the pain did resolve with decadron. on the patient had ventricular drain removed, her iv fluid continued at 125 per hour and she remained neurologically intact, awake, alert and oriented times three, moving all extremities strongly. she was transferred to the regular floor on . her iv fluids were discontinued on and patient was discharged to home on in stable condition after being evaluated by physical therapy and occupational therapy and found to be safe for discharge home. follow-up: dr. in 10 days to two weeks. discharge medications: levoxyl 50 mg po q day, zantac 150 mg po bid, nimodipine 60 mg po q 4 hours until , prednisone 2.5 mg po q day, vioxx 25 mg po q day, vitamin d 400 units po q d, calcium carbonate 1250 mg po bid, decadron to be tapered over one week. vital signs remain stable and patient was afebrile in stable condition at the time of discharge. , m.d. dictated by: medquist36 procedure: intravascular imaging of intrathoracic vessels other endovascular procedures on other vessels diagnoses: obstructive hydrocephalus unspecified essential hypertension acute posthemorrhagic anemia unspecified acquired hypothyroidism subarachnoid hemorrhage rheumatoid arthritis 

Answer: The patient is high likely exposed to
