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 is a 39 year old man with the sudden onset of mediastinal pain. no prior history of pain or cardiac problems. presented to an outside hospital, where a cat scan showed a type a dissection. the patient was then transferred emergently to the . past medical history: significant only for asthma and gerd. past surgical history: none. medications: meds at home include combivent and occasional prilosec. allergies: no known drug allergies. social history: no tobacco use. occasional alcohol use. physical examination: vital signs: heart rate 62. blood pressure 110/54. respiratory rate 20. general: no acute distress. heent: sclerae icteric. conjunctivae non-injected. mucous membranes moist. neck is supple with no lymphadenopathy. lungs clear to auscultation bilaterally. cardiovascular: regular rate and rhythm with 3/6 murmur at the right sternal border. pulses are symmetrical bilaterally. abdomen is soft and nontender and nondistended. extremities: warm and well perfused with no cyanosis, clubbing or edema. neuro: alert and oriented x3. moves all extremities. nonfocal exam. laboratory data: sodium 140, potassium 4.4, chloride 106, co2 26, bun 14, creatinine 1.4, glucose 109, albumin 3.4. white count 5.4, hematocrit 39, platelets 278. chest ct with ascending aortic dissection through the arch to the abdominal aorta. no pericardial effusion. hospital course: the patient was brought emergently to the operating room. please see the or report for full details. in summary, he had an emergent ascending aorta repair with a #28 sidearm gelweave graft, as well as an avr with a #25 - pericardial valve. his bypass time was 158 minutes with a cross clamp time of 124 minutes, and circ arrest of 16 minutes. he tolerated the operation well and was transferred to the cardiothoracic intensive care unit. at the time of transfer he was in a sinus rhythm at 100 beats per minute. he had propofol infusion at 20 mics per kilogram per minute and nitroglycerin at 1.5 mics per kilogram per minute. in the immediate postoperative period, the patient remained hemodynamically stable. however, he had a fair amount of bleeding and required several transfusions of packed red blood cells, as well as fresh frozen plasma. the patient also had difficulty with ventilation. an initial attempt to awaken the patient, his o2 sats dropped into the 80's. following several recuperative breaths, the patient was re-sedated and chemically paralyzed. over the next several days the patient continued to experience difficulty with ventilation. by chest x-ray it appeared that he had early onset ards. a pulmonary consult was called. additionally the patient suffered from persistent fevers, for which he was pan cultured on numerous occasions. infectious disease consult was also called. eventually the patient grew methicillin sensitive staph from his sputum and was treated with appropriate antibiotics. from a respiratory standpoint the patient remained paralyzed and sedated and fully ventilated. he had numerous bronchoscopies. over the next week or so, the patient made slow progress from a pulmonary standpoint, to the point where the paralytics were to be discontinued. however, every attempt to turn down his sedation and remove the paralytics was met with increased hypoxia, as well as acidosis requiring reinstitution of these measures. during this entire period the patient was undergoing bronchoscopy on an every other day basis. on postoperative day 9 the patient was noted to have bilateral pleural effusions. a right thoracentesis was performed on that day and drained about 600 cc of serosanguineous fluid. later in the day the patient became hemodynamically unstable. a chest x-ray revealed a left-sided pneumothorax. bilateral chest tubes were placed and a swan- ganz catheter was also placed. additionally following the placement of the swan-ganz catheter, the patient appeared to be septic and his antibiotic coverage was broadened. the patient recovered from this setback, and by postoperative day 14 the patient's paralytics were discontinued. he did, however, continue to require full ventilation and was sedated with morphine and ativan, which were slowly weaned over the next several days. over the course of the next week, the patient continued to make progress with his vent wean, until postoperative day 24, when the patient was strictly on pressure support, he developed a mucous plug, then became bradycardic and ultimately had a short period of asystole. with aggressive pulmonary toilet, as well as bag ventilation, the patient recovered from this episode. an ep consult was called. they saw no need for a temporary or permanent pacemaker at this point. however, thoracic surgery was also consulted and a trache and peg were placed on postoperative day 25, following which the patient had an episode of atrial fibrillation, from which he was dc cardioverted into a sinus rhythm. following trache and peg placement, the patient continued to make progress with his pressure support weaned, and by postoperative day 30 he was having trache mask trials. by postoperative day 33 he was on strictly trache mask. at the time of this dictation the patient has been on trache call for approximately 5 days without requiring any ventilatory support. dictation ends here , procedure: insertion of intercostal catheter for drainage extracorporeal circulation auxiliary to open heart surgery parenteral infusion of concentrated nutritional substances diagnostic ultrasound of heart diagnostic ultrasound of heart enteral infusion of concentrated nutritional substances other electric countershock of heart thoracentesis thoracentesis percutaneous [endoscopic] gastrostomy [peg] temporary tracheostomy open and other replacement of aortic valve with tissue graft resection of vessel with replacement, thoracic vessels closed [endoscopic] biopsy of bronchus closed [endoscopic] biopsy of bronchus pulmonary artery wedge monitoring percutaneous [endoscopic] gastrojejunostomy operations on other structures adjacent to valves of heart diagnoses: esophageal reflux unspecified pleural effusion unspecified essential hypertension atrial fibrillation asthma, unspecified type, unspecified aortic valve disorders defibrination syndrome iatrogenic pneumothorax cardiac arrest methicillin susceptible pneumonia due to staphylococcus aureus pressure ulcer, lower back dissection of aorta, thoracic foreign body in larynx dermatographic urticaria 

Answer: The patient is high likely exposed to
