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: this patient is an 81-year-old male resident of nursing home who presented to the emergency department on status post a fall with increasing confusion. the patient was recently discharged from after a 2-week stay with nonconvulsive status and a question of herpes simplex virus encephalitis, now status post therapy with two weeks of valacyclovir. on the day of admission, he had increased agitation, change in mental status, and headaches after being found on the floor in the morning on the day of admission. he was also found with stool incontinence. in the emergency department, he had a negative head computed tomography, urinalysis with a possible urinary tract infection, with a negative culture to date, and was hypertensive. therefore, he was admitted to the medical intensive care unit. he was on levophed for one day. he was treated first with ceftriaxone and then vancomycin intravenously. subsequently, his stool was positive for clostridium difficile. a urine culture was negative. therefore, he was on flagyl intravenously and vancomycin by mouth. the patient also had an abdominal computed tomography demonstrating pan-colitis as well as a 5-cm x 4-cm abdominal aortic aneurysm. on transfer to the medicine service, the patient was off pressors. he was still with questionable mental status changes and with worsening delirium at night. past medical history: 1. question herpes simplex virus encephalitis an nonconvulsive status epilepticus. 2. history of a seizure disorder. 3. hypertension. 4. orthostatic hypotension. 5. coronary artery disease; status post myocardial infarction with right coronary artery stent in . 6. congestive heart failure (with an ejection fraction of 30%). 7. polymyalgia rheumatica. 8. history of temporal arteritis. 9. benign prostatic hypertrophy. 10. history of anemia; guaiac-positive. 11. history of clostridium difficile colitis. 12. status post lumbar spine fusion. 13. dementia. allergies: the patient has allergies to dilantin as well as intravenous contrast. medications on transfer: (to the medicine floor were) 1. trazodone 12.5 mg by mouth at hour of sleep. 2. vancomycin 125 mg by mouth q.6h. 3. flagyl 500 mg intravenously q.8h. 4. metoprolol 50 mg by mouth three times per day. 5. morphine as needed. 6. aspirin 325 mg by mouth once per day. 7. haldol as needed. 8. tylenol. 9. subcutaneous heparin 5000 units subcutaneously three times per day. 10. carbamazepine 200 mg twice per day and 400 mg once per day. 11. .................... 0.1 mg by mouth once per day. 12. lipitor 10 mg by mouth once per day. 13. lansoprazole 30 mg by mouth once per day. 14. keppra 1 gram by mouth twice per day. social history: the patient does live in a nursing home. his wife past away in the last couple of years. physical examination on presentation: the patient's vital signs were stable. he was afebrile on transfer. on examination, the patient was alert and oriented to name only; not to place or date. he had trouble maintaining his level of alertness, closing his eyes and dosing off during examination. the patient was in no acute distress. he was wearing a venti mask with humidified oxygen. his heart was regular in rate and rhythm. the lungs were clear to auscultation bilaterally; only on anterior examination. his abdominal examination revealed the abdomen was soft and nontender. no hepatosplenomegaly. there was a mile erythematous rash over the lower torso. there was lower extremity edema. the pulses were 2+ bilaterally on the upper and lower extremities. pertinent laboratory values on presentation: on transfer to the medicine floor, the patient had a white blood cell count of 13.2 (down from 23.1), still with 10% bands, a platelet count of 91, and his hematocrit was 32.3. on chemistries, the patient had a potassium of 3.3. other chemistries were normal. he had no increased anion gap. other laboratory values were normal. the patient had a blood gas demonstrating a ph of 7.44, a pco2 of 28, and po2 of 70, and a bicarbonate of 20. recent cultures showed negative stool cultures but positive clostridium difficile toxin, negative blood cultures, and negative urine cultures. brief summary of hospital course: for the clostridium difficile colitis, the patient was maintained on flagyl intravenous as well as vancomycin by mouth four times per day. the intent was to stop the flagyl intravenously and decrease the vancomycin to twice per day after a full 2-week course of the four times per day. however, the patient developed further infectious during his hospitalization and was therefore kept on the flagyl intravenously and the vancomycin four times per day until after these other infections have resolved and then will continue the four times per day course for a total of two weeks and then remain on a twice per day course until his followup with gastroenterology (as has been arranged). the patient's mental status waxed and waned throughout his hospital course. he had bad reactions, as far as his mental status goes, to medications such as zyprexa as well as all other sedation. therefore, all other medications including narcotics and antipsychotics were discontinued except for haldol on an as-needed basis. the patient's mental status did improve throughout the course of his hospitalization; mostly, we believe, in response to treatment of his underlying infections; namely the clostridium difficile colitis as well as what was diagnosed as an epididymitis, as the patient had a urinalysis indicative of a urinary tract infection without any positive cultures and then had noted some scrotal tenderness. therefore, an ultrasound was obtained which showed a right epididymitis. therefore, the patient was started on ciprofloxacin twice per day for a total of a 10-day to 14-day course. it should be noted that the patient should continue on the treatment for the clostridium difficile colitis for a total of two weeks of the vancomycin four times per day starting to number the days again after the discontinuation of the ciprofloxacin; as per the infectious disease team in consultation. the patient did have further leukocytosis toward the end of his hospitalization, but no other source of infection was identified. the patient did have what was believed to be colonization with vancomycin-resistant enterococcus in his urine; although, he never had any increase in symptoms, fever spikes, or altered mental status after the appropriate treatment for the epididymitis and the clostridium difficile colitis. therefore, the vancomycin-resistant enterococcus was likely colonization. from a cardiovascular standpoint, the patient remained stable with an ejection fraction of 30%. he was continued on the medications for his congestive heart failure as well as for coronary artery disease; being metoprolol, aspirin, and a statin. the ace inhibitor was restarted for the congestive heart failure. from a fluids/electrolytes/nutrition standpoint, the patient was on total parenteral nutrition as he was taking poor oral intake due to his altered mental status. toward the end of his hospitalization, the patient's mental status drastically improved enabling him to take adequate oral intake. therefore, at the time of this dictation, the total parenteral nutrition was being weaned with the intention to be discontinued before the patient was discharged to a skilled nursing facility. note: the rest of this discharge summary dictation will be included in an addendum as the patient is discharged to a skilled nursing facility. it should be noted at this time, that the patient should have followup with gastroenterology as has been arranged and was to follow up with his primary care physician (dr. which will be arranged by dr. himself. at this time, the plan is to discharged this patient to a skilled nursing facility as soon as it is clear that he does not have any current infections and that his mental status maintains improved. , m.d. dictated by: medquist36 procedure: spinal tap incision of lung parenteral infusion of concentrated nutritional substances diagnoses: polymyalgia rheumatica congestive heart failure, unspecified acute kidney failure, unspecified unspecified septicemia severe sepsis intestinal infection due to clostridium difficile grand mal status abdominal aneurysm without mention of rupture giant cell arteritis 

Answer: The patient is high likely exposed to
