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 46-year-old female who developed a sudden severe headache on which awoke her from sleep. the headache started occipitally but involved the whole head. it felt like a tight squeezing. the patient went to the emergency department at an outside hospital where her systolic blood pressure was in the 160s. she received lopressor for her blood pressure, and a head computed tomography showed a small acute subarachnoid hemorrhage in the suprasellar cistern and fourth ventricle. no hydrocephalus. no atrophy. no edema. the patient was given demerol for pain and phenergan for nausea and vomiting. review of systems: on review of systems, the patient was in her usual state of health until this happened. the patient denies any visual symptoms, weakness or numbness, or speech and comprehension difficulties. the patient did report a 30-pound weight loss over the last several months and worked up by her primary care physician including thyroid studies. reportedly, all of those tests were negative (per the patient). she also had complained of some headaches, nausea, and vomiting that had begun on the morning before the severe headache started. past medical history: no past medical history. allergies: allergy to penicillin (which causes shortness of breath). medications on admission: she was not on any medications. social history: she is a positive smoker of half a pack per day for 10 years. she drinks socially. family history: no strokes or bleeding problems. father has cancer. physical examination on presentation: physical examination revealed vital signs with a temperature of 98.6 degrees fahrenheit, blood pressure was 160/80, heart rate was 74, respiratory rate was 11, and her oxygen saturation was 95% on room air. on general physical examination, she was awake and in no acute distress. she appeared comfortable. she spoke easily. neurologic examination revealed was alert, awake, and oriented times three. her speech was fluent. cranial nerve examination revealed the pupils were equal, round, and reactive to light; 2.5 mm to 2 mm bilateral. extraocular movements were full. no visual field deficits. she did have some difficulty wrinkling her forehead. weak frontalis. also, could not keep her eyes closed against resistance. her smile was symmetric but weak. puffed out cheeks. sternocleidomastoid were 4+/5. shoulder shrug was intact. motor examination revealed bulk was normal. strength on the left was on the left on both upper and lower extremities. strength on the right revealed her biceps were 4+/5 and triceps were . the remainder of the examination on the lower extremities was normal. she had slight pronator drift of her right arm. positive clonus. sensation was intact to light touch. proprioception was intact bilaterally. coordination examination revealed she had a positive resting tremor. reflexes were 2+ throughout. pertinent radiology/imaging: cervical spine at the outside hospital was negative for a fracture. pertinent laboratory values on presentation: her prothrombin time was 10.8 and partial thromboplastin time was 26.8. her white blood cell count was 8, her hematocrit was 38, and her platelets were 295. hospital course by issue/system: the patient was transferred to the intensive care unit where she was monitored. she was to have arterial line put in. her systolic blood pressure was to be kept at less than 140 with a nipride drip. she was kept nothing by mouth. she was typed and crossed for 2 units, and she was to go to angiogram later that day. later in the day on , it was noted the patient had decreased alertness and changes in her mental status. the patient was slightly more confused, and her repeat computed tomography showed a subarachnoid hemorrhage with hydrocephalus. at that time, it was decided to put a ventriculostomy drain in place. it was placed without complications. the patient had a angiogram later that day on which was negative for any kind of aneurysm or bleeding that could be seen from a vessel. postoperatively, the patient was awake. she could follow some commands. she was alert. she did not have a drift. however, she did remain confused at times. on postoperative day one on , her intracranial pressures were in the 8 to 15 range. her cpp was 82 to 72. she was awake, alert, and slightly confused. full extraocular movements. her upper and lower extremities were equal bilaterally. she remained in the intensive care unit. on , her computed tomography was stable. no further bleeding. her head computed tomography showed good placement of the ventriculostomy drain. her ventriculostomy drain at this point was at 15 cm of water. the patient was requiring hydralazine, captopril, and metoprolol to maintain her blood pressure at less than 140. on , the patient did have a headache overnight; although they were relieved with tylenol. she was able to advance her diet. she was able to starting eating. at this point, her coagulations were within normal limits. her inr was 1.2. her captopril was increased on to maintain her blood pressure at less than 160. during the time when her ventriculostomy drain was in, she was no prophylactic vancomycin. on , the patient was awake, alert and oriented times three. at this point, she still continued to have her ventriculostomy drain in. her blood pressures were in the 130s systolic and 50s to 70s diastolic. on , the patient's ventriculostomy drain was raised to 20. on , it was raised to 25. the patient was able to get out of bed intermittently, and she remained awake, alert, and oriented during these increases. the patient did have a subclavian quad-lumen catheter placed on for intravenous access to receive her vancomycin. that was placed without any problems. on , the ventriculostomy drain was clamped. she seemed to tolerate that well. on , the patient was transferred out of the intensive care unit. her ventriculostomy drain was discontinued on earlier in the day, and she had done well. a repeat computed tomography did not show any hydrocephalus. she was awake, alert and oriented times three. she was discharged out of the intensive care unit late in the evening on . on , the patient had an angiogram done which showed no bleeding or evidence of aneurysm. it showed no evidence of arteriovenous malformation or avf. there was some diffuse vasospasm. at that point, the patient was started on amlodipine 30 mg q.4h. which kept her systolic blood pressure at greater than 120. her blood pressure medications were readjusted so she was only on lopressor 25 mg twice per day. she was already on subcutaneous heparin which was continued. the patient was also continued on intravenous fluids at 100 cc per hour. she was seen by physical therapy. on , the patient was doing well. her central line was discontinued. her foley catheter was discontinued. she was continued on the amlodipine and intravenous fluids. intravenous fluids were decreased to 50 cc per hour. it was also felt that the patient should stay in the hospital until day sixteen from the original bleed. during her time of the floor, she was seen by physical therapy who helped her and felt that her goals were achieved, and she was safe to go home as of . on , the patient was awake, alert and oriented times three. her intravenous fluids were stopped. she was tolerating a diet. her upper and lower extremity strength were equal bilaterally. discharge instructions/followup: (the patient was discharged on the with the following instructions) 1. the patient was to return back to the emergency department if she developed a severe headache or any kind of nausea associated with the headache. 2. the patient was to increase her activity to as tolerated. medications on discharge: 1. metoprolol 50-mg take one-half tablet by mouth twice per day. 2. amlodipine 30 mg by mouth q.4h. (for 13 days). , m.d. dictated by: medquist36 procedure: arteriography of cerebral arteries ventricular shunt to extracranial site nec diagnoses: obstructive hydrocephalus subarachnoid hemorrhage 

Answer: The patient is high likely exposed to
