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. was referred to dr. from his primary care physician (dr. . mr. was a healthy and active 88-year-old male with the only comorbidity of hypertension. he was diagnosed with an left renal mass that was 7 cm x 7 cm in diameter. there were also some lesions in the liver identified which were suggestive hemangioma and not metastatic fossae. he has no symptoms of hematuria, abdominal pain, weight loss, or fatigue. otherwise, he is a very active gentleman and has come to for elective removal of this renal mass. past medical history: 1. hypertension. 2. history of transient ischemic attack in with some right-sided weakness that has completely resolved. 3. status post open surgical removal of a left renal stone over 40 years ago. medications on admission: 1. atenolol 50 mg p.o. q.d. 2. hydrochlorothiazide 25 mg p.o. q.d. 3. multivitamin one tablet p.o. q.d. allergies: no known drug allergies. social history: a retired polymer chemist. he does not smoke. he drinks one cup of coffee per day. he rarely drinks alcohol. physical examination on presentation: on physical examination his vital signs revealed blood pressure was 126/72, heart rate was 60, and respiratory rate was 14. head, eyes, ears, nose, and throat examination was within normal limits. his lungs were clear to auscultation bilaterally. his heart was regular in rate and rhythm. his abdomen was soft and nontender. no palpable masses. no costovertebral angle tenderness. no lymphadenopathy. genitourinary examination revealed he had a normal phallus, meatus, and testes. no inguinal hernia. his rectal examination revealed normal tone, a 45-g prostate, and no nodularity. his extremity examination was within normal limits. pertinent radiology/imaging: a magnetic resonance imaging revealed simple bilateral renal cysts in addition to the large 7-cm left mid upper pole renal mass pressing on the splenic vein. hospital course: on , the patient went to the operating room and underwent a left radical nephrectomy. during the operation, the splenic artery was injured secondary to the position of the mass abutting against the splenic artery. at that point, general surgery was consulted, and the patient underwent a splenectomy on top of his left radical nephrectomy. the estimated blood loss was cc. the patient received 3 units of packed red blood cells in the operating room. he also received 5400 cc of crystalloid. please refer to the official operative notes for all of the details. after the patient was sent to the postanesthesia care unit, he was still intubated and went to the intensive care unit secondary to the blood loss. the patient was in the intensive care unit overnight, and the next morning was able to be extubated. the patient was also cycled on enzymes which were negative. after the patient was extubated on postoperative day one, the patient was quite stable and was able to be transferred to the floor. an nasogastric tube was left in place to decompress the stomach, and he was also on an epidural. on the floor, the patient did well over the next few days. serial hematocrit levels were checked; which were stable initially. immediately on transfer to the floor, over the next few days, the patient had some decreased mental status including agitation and sundowning. however, after a few days, this did clear. there were no focal abnormalities, just disorientation of mental status. the patient did require some intravenous haldol with a good response, and the dilaudid was removed the patient's epidural as narcotics were minimized. also of note, the patient had some expiratory wheezing and some low oxygen saturations at times and received some albuterol nebulizers with a good response. on postoperative day four, the nasogastric tube was removed, and the patient began to ambulate. it was noted around postoperative day four that the hematocrit was slowly trending down, so the patient was transfused 2 units of packed red blood cells with a good response. by postoperative day seven, the patient was ready for discharge. he was tolerating a regular diet, and having bowel movements. the foley catheter had been discontinued, and the patient was urinating on his own. of note, the patient was given his remaining two vaccines because he had previously received a pneumovax vaccine. he received the h-flu and the meningococcus vaccine. his staples were also removed prior to discharge on postoperative day seven. condition at discharge: the patient's was stable;

Answer: The patient is high likely exposed to
