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: allergies: no allergies/adrs on file attending: chief complaint: sah major surgical or invasive procedure: bilateral evd placement history of present illness: mrs. is a very unfortunate 55 yo woman with unknown past medical history who presents with a massive sah. she was apparently in her usoh until this evening when she was at a restaurant, complained of headache and said that she wanted to go to the bathroom. when she didn't come out, she was found down in the bathroom. past medical history: unknown social history: unknown family history: unknown physical exam: upon arriving here, she was seemingly moving all four extremities and was oriented to name. she then vomited, prompting her to be intubated. head ct showed thick sah with possible left acomm aneurysm, with significant ivh and hydro, casting of the 4th ventricle and obscuration of the basal cisterns. when i saw her, 5 minutes off of propofol, she was extensor posturing. pertinent results: ct head: impression: hemorrhage distending entire ventricular system and also subarachnoid hemorrhage in the cisterns, along bifrontoparietal sulci and interhemispheric fissures, with cerebral edema and evolving hydrocephalus. 13-mm left frontal relatively focal hematoma suggestive of aneurysm rupture, as confirmed on subsequent cta, with a source aneurysm arising from the left supraclinoid ica. cta head: impression: 1. 10 x 8 mm aneurysm, arising dorsally from the left supraclinoid carotid artery surrounding by hematoma, likely indicating recent rupture. 2. the major vessels in the circle of are patent, including the basilar artery. the patient is status post interval placement of bilateral frontal approach intraventricular shunt catheters, with tips terminating in the lateral ventricles, intraventricular and diffuse subarachnoid hemorrhage, not significantly changed since the preceding head ct. brief hospital course: mrs. is a very unfortunate 55 yo woman with unknown past medical history who presents with a massive sah. she was apparently in her usoh until this evening when she was at a restaurant, complained of headache and said that she wanted to go to the bathroom. when she didn't come out, she was found down in the bathroom. upon arriving here, she was seemingly moving all four extremities and was oriented to name. she then vomited, prompting her to be intubated. head ct showed thick sah with possible left acomm aneurysm, with significant ivh and hydro, casting of the 4th ventricle and obscuration of the basal cisterns. when i saw her, 5 minutes off of propofol, she was extensor posturing. dr. immediately came to patient's bedside and placed 2 evds (one on each side), one of which is at 10 and the other of which is currently open. with placement of the evd, it was noted that 200cc of fresh blood came out. a cta was performed right after this and showed a clear left acomm vs. a2 aneurysm. subsequent to the cta dr. the patient and found her to have fixed and dilated pupils. dr. then felt that angiography would be too risky given her active herniation. at this time, the patient has a dismal prognosis. as a result, we will pursue end-of-life discussions with the family and elicit their wishes. patient pronounced at 4:19 a.m. proximate cause of death was cardiopulmonary arrest. main cause of death was transtentorial cerebral herniation secondary to subarrachnoid hemorrhage. examination shows fixed and dilated pupils. no corneals, no gag, no doll's. no pulse, no breath sounds, no heart sounds. medications on admission: unknown discharge medications: expired discharge disposition: expired discharge diagnosis: sah hydrocephalus aneurysm cerebral edema discharge condition: expired discharge instructions: expired followup instructions: expired procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours insertion of endotracheal tube insertion or replacement of external ventricular drain [evd] diagnoses: unspecified viral hepatitis c without hepatic coma subarachnoid hemorrhage compression of brain do not resuscitate status 

Answer: The patient is high likely exposed to
