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: patient recorded as having no known allergies to drugs attending: chief complaint: chest pain major surgical or invasive procedure: mitral valve repair with 36 mm annuloplasty ring (future cg)and posterior leaflet cleft repair history of present illness: 39 yo male with known murmur was hospitalized in early for angina. murmur noted, pain resolved, and subsequent ett/echo scheduled. ett was stopped for fatigue and was non-diagnostic for ischemia. echo revealed moderate to severe mr. past medical history: mitral regurgitation atrial fibrillation with dccv social history: occupation: biotechnician last dental exam: dental clearance obtained lives with wife : caucasian tobacco: active ppd, reduced on chantix etoh: social occasions family history: non-contributory physical exam: pulse: 76 reg resp: o2 sat: b/p right:136/86 left: 138/82 height: 72" weight: 185# general:sl. anxious skin: dry intact heent: perrla eomi anicteric sclera;op benign neck: supple full rom chest: lungs clear bilaterally heart: rrr irregular murmur- 3/6 sem heard best at apex abdomen: soft non-distended non-tender bowel sounds + no hsm/cva tenderness extremities: warm , well-perfused edema none varicosities: none neuro: grossly intact, nonfocal exam; mae / strengths pulses: femoral right: 2+ left: 2+ dp right: 2+ left: 2+ pt : 2+ left: 2+ radial right:2+ left: 2+ carotid bruit right: none left: none pertinent results: echo: pre-bypass: the left atrium is normal in size. no spontaneous echo contrast or thrombus is seen in the body of the left atrium or left atrial appendage. no atrial septal defect is seen by 2d or color doppler. overall left ventricular systolic function is mildly depressed (lvef= 40-45 %). right ventricular chamber size and free wall motion are normal. the ascending, transverse and descending thoracic aorta are normal in diameter and free of atherosclerotic plaque. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. the mitral valve leaflets are myxomatous. there is moderate/severe mitral valve prolapse. mild to moderate (+) mitral regurgitation is seen. there is no pericardial effusion. post. cpb: 1. there was a detriorqtion in imaging quality and poor visualization of the mitral valve and left ventricle from the mid-esophageal windows, probably due to the positioning of the heart. 2. only limited evlauation of the mitral valve. annuloplasty ring in the mitral position. seems well seated and stable. good leaflet excursion. there was only trace mitral regurgitation and no evidence of dynamic lvot obstruction. 3. left ventricular function is mildly improved globally. 4. no other change. 07:45am blood wbc-6.7 rbc-4.40* hgb-13.1* hct-37.9* mcv-86 mch-29.8 mchc-34.6 rdw-12.4 plt ct-297# 06:00am blood glucose-103 urean-18 creat-1.3* na-135 k-4.3 cl-104 hco3-23 angap-12 brief hospital course: mr. was a same day admit after undergoing pre-operative work-up prior to admission. on he was brought to the operating room where he underwent a mitral valve repair. please see operative report for details. following surgery he was transferred to the cvicu for invasive monitoring in stable condition. within 24 hours he was weaned from sedation, awoke neurologically intact and extubated. on post-op day one he was transferred to the telemetry floor further care. chest tubes and epicardial pacing wires were removed per protocol. he was placed on antibiotics for sternal incision erythema. this erythema improved by post-operative day five and he was cleared for discharge to home. medications on admission: xanax prn discharge medications: 1. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 2. metoprolol tartrate 25 mg tablet sig: 0.5 tablet po tid (3 times a day). disp:*45 tablet(s)* refills:*2* 3. keflex 500 mg capsule sig: one (1) capsule po four times a day for 5 days: sternal incision erythema. disp:*20 capsule(s)* refills:*2* 4. hydromorphone 2 mg tablet sig: 1-2 tablets po q3h (every 3 hours) as needed for pain. disp:*40 tablet(s)* refills:*0* 5. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day) as needed for constipation. disp:*30 capsule(s)* refills:*0* 6. furosemide 20 mg tablet sig: one (1) tablet po once a day for 5 days. disp:*5 tablet(s)* refills:*2* 7. potassium chloride 20 meq tab sust.rel. particle/crystal sig: one (1) tab sust.rel. particle/crystal po once a day for 5 days. disp:*5 tab sust.rel. particle/crystal(s)* refills:*2* discharge disposition: home with service facility: vna of greater / discharge diagnosis: mitral regurgitation s/p mitral valve repair atrial fibrillation with dccv discharge condition: good discharge instructions: no lotions, creams, powders or ointments to incision no driving for one month no lifting greater than 10 pounds for 10 weeks call for fever greater than 100, redness, drainage, or weight gain of 2 pounds in 2 days or 5 pounds in one week shower daily at pat incison dry;

Answer: The patient is high likely exposed to
