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: patient is a 77-year-old gentleman status post a right frontal vp shunt placement on , who has been doing well until mid when he began complaining of headache. he was admitted to the at that time with a subdural hematoma. the vp shunt was ligated, and the patient was discharged to rehab again. head ct at that time of d/c showed increased hydrocephalus, but stable. patient was sent to rehab and became increasingly confused and not able to follow coherent streams of thought or commands. family called dr. and felt that repeat head ct needed to be done which showed an increase in the subdural hematoma especially on the left to 3-4 cm in width, and the patient was admitted for bedside drainage. past medical history: 1. diabetes. 2. hypertension. 3. hypercholesterolemia. 4. benign prostatic hypertrophy. 5. incontinence. 6. nph. 7. peptic ulcer disease. 8. chronic renal insufficiency with a creatinine of 2. 9. dementia. 10. clostridium difficile. 11. ataxia. 12. cellulitis. the patient was admitted to the icu. physical examination: his temperature was 98.3. blood pressure was 136/62. heart rate 69. respiratory rate 17. sats 97%. heent: neck was supple, no meningismus. mental status: awake and alert, but not oriented. language is fluent. attention is slow, but intact. recall is 0/4. cranial nerves ii through xii intact. motor exam: strength in the upper extremities: his right deltoid, wrist extension, and triceps are . does not follow commands to the left. sensory is really unable to test. does not follow commands. reflexes were 0 in the upper extremities, 2+ at the knees, 0 at the ankles. his toes withdraw. hospital course: he was admitted to the icu setting. had a bedside drainage of a subdural hematoma without interprocedural complication. the patient had the drain left in place overnight. ct on after bedside drainage shows unchanged right subdural hematoma, left subdural fluid collection was slightly increased. repeat scan that the drainage procedure was unsuccessful, and ........... the left subdural hematoma. therefore, the patient was taken to the or on to undergo a craniotomy and drainage of the left subdural hematoma. the surgery of the drainage of the subdural was on . on , the patient opened his eyes to voice. his speech was dysarthric. he was following commands, squeezing hands, flexing his legs, showing two fingers. drain put out 30 cc. patient had a head ct, which showed a decrease in the size of the left subdural fluid collection and decrease in the left to right midline shift. no change in ventricle size. patient's drain was removed. on , he was arousable by voice, drowsy, tended to keep his eyes closed. not really following commands. speech was fluent, but mumbled. he was spontaneously moving his upper and lower extremities and purposeful. on , the patient dropped his sats and had a blood gas with a po2 of 52. the patient was urgently intubated. there were no complications with intubation. chest x-ray showed decrease in the volume on the left side. cta showed no evidence of pulmonary embolus. ultimately when patient was opening his eyes, biceps were on the right, on the left. he moves his feet to commands. follows commands inconsistently. he had a head ct on which showed a left frontal collection with no change and no change in the ventricle size. tap of the vp shunt on showed an opening pressure of 25, and patient remained neurologically stable, arousable, following commands, opening eyes. repeat head ct was done which showed worsening subdural hematoma. patient had externalization of his vp shunt. was extubated on successfully without any problems. on , neurologically opening his eyes to voice. withdraws briskly to stimulation. he is purposeful on the left greater than right. his drain was at 15 cm above the tragus, now raised to 20. the vent drain was changed to 5-10 cc an hour titrating to get 5-10 cc/hour of csf drainage. ct on showed decrease in subdural fluid and no change in ventricular size. on the 26th, the patient was awake and following commands, attentive, and face was symmetric. he had antigravity strength in his bilateral upper extremities left greater than right. grasps were on the left, on the right. ips is bilaterally. patient was out of bed sitting in a chair. drain was raised to 25 cm above the tragus and titrated to keep drainage 10 cc every four hours. on , the patient went to the operating room to have revision of his vp shunt. he tolerated the procedure well. there were no intraoperative complications. postoperatively, he was monitored in the intensive care unit. he was awake, attentive, localizing briskly in the upper extremities, withdrawing bilateral lower extremities. his incision was clean, dry, and intact. on , patient status post vp shunt revision was awake, dysarthric, no drift, and impersistently following commands. his vital signs were stable. he was transferred to the regular floor on . on , he was awake..... incomplete dictation , m.d. dictated by: medquist36 procedure: percutaneous [endoscopic] gastrostomy [peg] other incision of brain replacement of ventricular shunt gingivoplasty ventriculopuncture through previously implanted catheter diagnoses: pure hypercholesterolemia unspecified essential hypertension diabetes mellitus without mention of complication,

Answer: The patient is high likely exposed to
