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: mr. is a 72-year-old gentleman diagnosed with ulcerative colitis two years ago. since then, he has been treated with asacol and rowasa and has not had any acute flares since his initial diagnosis. however, over the past couple of months he has been experienced abdominal cramping and bloody diarrhea. this prompted him to have a colonoscopy and sigmoidoscopy on . after these scopes, his medications were changed to prednisone 60 mg p.o. q.a.m. he failed to improve and began have profuse bloody diarrhea, decreased oral intake, and nausea, and abdominal cramping. he went to an outside hospital and was treated with intravenous hydrocortisone 100 mg q.8h., ciprofloxacin 400 mg, flagyl, as well as starting partial parenteral nutrition. he failed to improve and was transferred to for further management. past medical history: 1. ulcerative colitis. 2. a myocardial infarction in ; status post right coronary artery and left anterior descending artery stents. 3. one episode of atrial fibrillation that cardioverted electrically. 4. appendectomy. 5. cholecystectomy. 6. diverticulosis in the past. 7. kidney stones. 8. pancreatitis many years ago. medications on admission: 1. aspirin 325 mg p.o. q.d. 2. protonix 40 mg p.o. q.d. 3. lipitor 10 mg p.o. q.d. 4. asacol 800 mg p.o. t.i.d. 5. rowasa. 6. metoprolol 12.5 mg p.o. b.i.d. 7. captopril 6.25 mg p.o. t.i.d. allergies: no known drug allergies. social history: the patient smoked one pack of cigarettes per day for 20 years and quit 30 years ago. he has about one beer per week. physical examination on presentation: on arrival, his vital signs revealed temperature was 97.3, blood pressure was 140/70, heart rate was 88, respiratory rate was 20, oxygen saturation was 98% on room air. in general, this was a thin male who appeared younger than 72 years of age. head, eyes, ears, nose, and throat examination revealed the oropharynx was clear. mucous membranes were moist. cardiovascular examination revealed a regular rate and rhythm. no murmurs. the chest was clear to auscultation bilaterally. the abdomen was soft, tender diffusely more so in the right lower quadrant, positive bowel sounds. no rebound. extremity examination revealed thin with no edema. pulses were 2+ bilaterally. pertinent laboratory values on presentation: laboratories on admission revealed white blood cell count was 9.2, hematocrit was 39.1, and platelets were 162. differential with 47% bands. chemistry-7 revealed sodium was 134, potassium was 3.8, chloride was 101, bicarbonate was 27, blood urea nitrogen was 21, creatinine was 0.8, and blood glucose was 113. alt was 27, ast was 13, alkaline phosphatase was 65, total bilirubin was less than 0.1, total protein was 4.7, and amylase was 92. triglycerides were 54. erythrocyte sedimentation rate was 25. at the outside hospital, he had a stool that was negative for clostridium difficile, salmonella, shigella, ova and parasites, and was positive for white blood cells. radiology/imaging: he had an echocardiogram in which showed trivial mitral regurgitation, trivial tricuspid regurgitation, with an ejection fraction was 35% to 40%. posterior akinesis. posterolateral intraseptal hypokinesis. at the outside hospital, the patient had a computed tomography of the abdomen and pelvis without contrast which showed gastric distention of the transverse colon without appreciable wall thickening. no cecal distention. a large amount of stool in the cecum. diverticula. this was read as no definite evidence of acute ulcerative colitis. hospital course: the patient was admitted to the medicine service for management of a likely ulcerative colitis flare. the patient was started on solu-medrol at a total of 60 mg every 24 hours. more stool studies were sent. the patient was kept nothing by mouth on intravenous fluids. aspirin was held secondary to bloody diarrhea. the patient was continued on intravenous steroids; he received five days of intravenous steroids at the outside hospital before being transferred. he did not improve significantly. he continued to have crampy abdominal pain and a bloody diarrhea. a sigmoidoscopy was performed on showing diffuse continuous severe friability with contact bleeding in the rectum to 40 cm; however, the disease appeared to continue beyond 40 cm. the findings were consistent with ulcerative colitis; however, viral colitis cytomegalovirus could not be ruled out. biopsy were performed which showed no viral inclusions, granulocytes, dysplasia and was consistent with severe ulcerative colitis. surgery was consulted, and the risk and benefits of surgery were discussed with the patient, and the patient decided that surgery was what he wanted. the patient received a cardiology preoperative evaluation which included a chemical stress test which showed no anginal symptoms or ischemic st changes. cardiology suggested a cardiac catheterization be performed on the morning of surgery which showed normal left ventricular end-diastolic pressure. no mitral regurgitation. mild mitral valve prolapse. ejection fraction of approximately 50%. mild anterolateral and apical hypokinesis. severe posterobasal inferior hypokinesis. coronary angiography showed a right-dominant vasculature. the left main coronary artery with a proximal 20% stenosis. left anterior descending artery with mild in-stent restenosis medial portion of 40%. first obtuse marginal with proximal 80% stenosis. right coronary artery with proximal mild luminal irregularities with minimal in-stent restenosis. the patient was cleared for surgery, a total colectomy with ileostomy was performed. the patient's current cardiac regimen was continued including beta blocker, and the patient was taken to the operating room. estimated blood loss was 400 cc. no complications. the patient was taken to the intensive care unit for close monitoring. he was stable and extubated upon arrival. the patient's postoperative hematocrit was 36.8, and the patient was transfused packed red blood cells with a goal hematocrit of above 30 considering his coronary artery disease. the patient was continued on a steroid taper and 24 hours of antibiotics were continued. the patient did well and was transferred to the floor on postoperative day one. he continued on a steroid taper, and his nasogastric tube was discontinued on postoperative day three, and the patient's hematocrit was 28.6, and made good urine output, and the foley was discontinued, and the ostomy had no stool or gas output yet. the patient was started on clears on postoperative day four which he tolerated well. he began to have output from his stoma that was liquid/green in nature and was quickly advanced to clear liquids and then a regular diet which he tolerated well. the patient's main issue in the hospital has been orthostatic hypotension. the patient continually felt lightheaded upon standing and ambulating, and orthostatics were done showing a drop in blood pressure into the 60 to 70 systolic range upon standing. at that point, it was decided to increase his steroids to 60 mg of prednisone every day and to transfuse him a couple of units of packed red blood cells which brought him up to a hematocrit of 35. discharge disposition: he did well with physical therapy over the past couple of days prior to discharge; being able to ambulate on his own with no symptoms of dizziness or lightheadedness, and he had been tolerating a regular diet with good ostomy output, formed stool, and was ready for discharge on to home with home physical therapy as well as visiting nursing care for stoma care. medications on discharge: the patient was discharged on a slow prednisone taper starting at 60 mg p.o. q.d. and will taper off over the course of six weeks. the patient had not needed anything for pain in the past week. the patient was discharged on metoprolol 12.5 mg p.o. b.i.d. and protonix 40 mg p.o. q.d. discharge instructions/followup: the patient was to follow up with dr. in two weeks. his staples were to be removed prior to discharge. m.d. dictated by: medquist36 procedure: coronary arteriography using two catheters angiocardiography of left heart structures left heart cardiac catheterization temporary ileostomy closed [endoscopic] biopsy of large intestine diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension personal history of tobacco use other and unspecified hyperlipidemia old myocardial infarction orthostatic hypotension other ulcerative colitis 

Answer: The patient is high likely exposed to
