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: the patient is a 74-year-old gentleman who is status post pedestrian versus automobile where the patient was wedged under the front bumper. no loss of consciousness. the patient is cantonese-speaking only. past medical history: the patient past medical history includes question hypertension and question gastrointestinal issues. the patient drinks two to three drinks per night and has a history of one and a half packs per day times 30 years. allergies: the patient has no known drug allergies. physical examination on presentation: the patient's vital signs on examination revealed a heart rate of 72, his blood pressure was 180/palp, his respiratory rate was 28, and his oxygen saturation was 100% on nonrebreather. the patient's physical examination revealed the pupils were equal, round, and reactive to light bilaterally. the extraocular muscles were intact. the tympanic membranes were clear. the oropharynx was clear. cardiovascular examination revealed a regular rate and rhythm. the lungs were clear to auscultation bilaterally. chest examination revealed left-sided tenderness. the abdominal was significant for a tender upper quadrant bilaterally. the abdomen was soft and nondistended. the pelvis was stable. no deformities or costovertebral angle tenderness. back examination revealed negative cervical spine. rectal examination was negative with good tone. the patient's extremity examination was significant for a right ankle abrasion; otherwise was unremarkable. coma scale was 15 (via interpreter). pertinent laboratory values on presentation: the patient's white blood cell count was 8.7, his hematocrit was 37.7, and his platelets were 211. electrolytes were within normal limits. lactate was 2.2. pertinent radiology/imaging: a chest x-ray showed bilateral pulmonary contusions, right ribs four through eight fractures, left hemothorax, and a l2 compression fracture; question chronicity. the patient's computed tomography scan of the abdomen showed thickening of the pylorus. the patient also had a distal right clavicular fracture and a right hallux fracture. concise summary of hospital course: the patient was transferred to the intensive care unit for close monitoring of respiratory status. the patient's hematocrit dropped to 23, and the patient became hypotensive at this time. the patient received intravenous fluids resuscitation and 2 units of packed red blood cells. a chest tube was placed on for the left hemothorax and respiratory distress. a left subclavian central line was also placed as well as an arterial line on . the patient's intensive care unit course included packed red blood cells on an as needed basis and chest tube to wall suction. cardiothoracic surgery was consulted to comment of utility of a video-assisted thoracic surgery procedure. cardiothoracic surgery were following, and due to improvement of output, they decided to treat conservatively. the orthopaedic service was also consulted regarding the l2 compression fracture, rib fractures, and hallux fracture. a magnetic resonance imaging of the lumbar spine was obtained which showed the compression fracture to be chronic in nature. the orthopaedic service also thought the right hallux fracture and clavicular fracture were nonoperative, and the patient was recommended to follow up with orthopaedics in three weeks. on hospital day five, the patient was transferred to the floor. he was afebrile and hemodynamically stable. the patient's chest tube output remained stable at approximately 300 cc to 400 cc of serosanguineous fluid per day. the patient was kept on subcutaneous heparin and sequential compression device for deep venous thrombosis prophylaxis throughout the hospital course as well as protonix once per day for gastrointestinal prophylaxis. during the hospital course, the patient's platelets decreased minimally. a heparin-induced thrombocytopenia antibody was sent and found to be negative. on hospital day ten, the patient's chest tube output had decreased to approximately 200 cc per day. the chest tube was put to water seal, and a chest x-ray was obtained in the morning. this chest x-ray showed a left pleural effusion. the patient remained asymptomatic with oxygen saturations of 97% on room air. note: an addendum to the hospital course will follow. condition at discharge: the patient's condition on discharge was stable. discharge disposition: discharge disposition was to rehabilitation (per physical therapy and family wishes). discharge diagnoses: 1. status post struck pedestrian. 2. bilateral pulmonary contusion. 3. left hemothorax; status post chest tube placement. 4. rib fractures (right ribs four through eight). 5. l2 compression fracture (chronic). 6. pylorus thickening (via computed tomography scan of the abdomen). 7. right hallux fracture. 8. right distal clavicular fracture. major surgical/invasive procedures performed: 1. the patient is status post left chest tube placement on . 2. the patient is status post left subclavian central line placement on . 3. the patient is status post left radial arterial line placement on . discharge instructions/followup: 1. the patient was instructed to follow up in the trauma clinic in two weeks and was to call the office for appointment. 2. the patient was instructed to follow up with orthopaedics (dr. in two weeks after discharge. 3. the patient was also instructed to follow up with his primary care physician regarding the new finding of pylorus thickening on computed tomography of the abdomen (which was done on ). 4. the patient was also instructed to follow up with his primary care physician regarding blood pressure medications. the patient's heart rate and blood pressure remained stable on lopressor 25 mg by mouth twice per day. 5. the patient's treatment at rehabilitation include vital signs per routine and oxygen saturations, wound checks, medication overview, and physical therapy as per physical therapy. the patient's comorbidities include question hypertension and question gastrointestinal issues. medications on discharge: (discharge medications included) 1. protonix 40 mg by mouth once per day. 2. lopressor 25 mg by mouth twice per day. discharge diet: as tolerated. discharge activity: as tolerated. , m.d. dictated by: medquist36 procedure: insertion of intercostal catheter for drainage venous catheterization, not elsewhere classified arterial catheterization transfusion of packed cells diagnoses: motor vehicle traffic accident involving collision with pedestrian injuring pedestrian closed fracture of lumbar vertebra without mention of spinal cord injury contusion of lung without mention of open wound into thorax traumatic hemothorax without mention of open wound into thorax closed fracture of multiple ribs, unspecified closed fracture of scapula, unspecified part closed fracture of clavicle, unspecified part 

Answer: The patient is high likely exposed to
