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 an 84-year-old gentleman status post an unwitnessed fall down a flight of stairs. positive amnesia to the event. the patient was transferred to an outside hospital with confusion. a computed tomography scan revealed a subarachnoid hematoma. the patient was transferred to the for further management of his head injury. the patient denied chest pain and abdominal pain. past medical history: 1. bioprosthetic valve replacement. 2. insulin-dependent diabetes mellitus. medications on admission: lopressor, imdur, aspirin, potassium, and detrol. allergies: no known drug allergies. physical examination on presentation: initial physical examination revealed his pulse was 80, his blood pressure was 138/palp, his respiratory rate was 16, and his oxygen saturation was 97% on room air. coma scale was 15. the pupils were equal and reactive bilaterally. the extraocular muscles were intact. the transcranial magnetic stimulation were clear bilaterally. midface had no deformities. there was a 3-cm laceration above the left eye. the patient's trachea was midline. the patient was in a regular rate and rhythm. his breath sounds were clear bilaterally. there was no stepoff of deformities of the back. the pelvis was stable. rectal examination was nasogastric with good rectal tone. extremities revealed no deformities or tenderness. there were palpable pulses bilaterally. brief summary of hospital course: the patient was admitted to the trauma intensive care unit for every 1-hour neurologic checks. the patient was seen by neurosurgery who concluded that the patient was stable and would need a head computed tomography in the morning on hospital day two. the patient was admitted to the trauma intensive care unit. an arterial line was placed without any complications. the patient's blood pressure was controlled without the need of pressors or nitroglycerin. the 3-cm head laceration was washed out and sutured with interrupted nylon sutures. neurosurgery's recommendations were to continue the pco2 between 35 and 40. they also wanted a magnetic resonance imaging of the cervical spine due to the patient's tenderness. early on , the patient was noted to have stridor and decreasing oxygen saturations. the patient was intubated without difficulty. during the patient's hospitalization stay, he was extubated twice. due to failure to clear secretions and failure of a gag reflex, he was reintubated. it was decided after the patient's third intubation that he would require a tracheostomy and an open gastrojejunostomy tube placement. a discussion took place between the trauma team and the patient's family. the patient's son agreed that a tracheostomy and a percutaneous endoscopic gastrostomy tube would be in his father's best interest. during that time, neurosurgery deemed the patient stable. they recommended follow up with dr. in two weeks after discharge and to continue to the cervical collar until discharge. during that time, the patient had sputum cultures which grew methicillin-susceptible staphylococcus aureus and had a urine culture which grew escherichia coli which was sensitive to levaquin. on , the patient had a left subclavian triple lumen placed for access and an arterial line placed. on , the patient was brought to the operating room with a preoperative diagnosis of respiratory failure due to the inability to clear secretions and loss of the gag reflex. the patient had gastrostomy and open tracheostomy by dr. , dr. , and dr. . the patient tolerated the procedure well with minimal blood loss. the patient was transferred to the trauma intensive care unit in stable condition. on postoperative day one, the patient's tube feeds were advanced to goal. on postoperative day two, the patient attempted a tracheostomy trial. during the night on postoperative day two, he was placed back on the ventilator for support due to tachypnea. on , it was decided that the patient was well enough to be discharged to a rehabilitation services with ventilator support. discharge physical examination revealed his temperature maximum 100.8/99.8, his blood pressure was 152/47, his heart rate was 68, his respiratory rate was 27, and 100% on a tracheostomy 50% mask. the patient's total ins for the day included 2500 cc of fluid and total outs of 1900 cc of fluid. the patient's white blood cell count was 9.6 and his hematocrit was 28.9. he was alert and oriented. he followed commands and moved all extremities. his pupils were equal and reactive. his extraocular muscles were intact. heart was regular in rate. his breath sounds were coarse bilaterally. his abdomen was soft, nontender, and nondistended. his incision was healing well. the patient had no peripheral edema. discharge diagnoses: 1. status post fall with subarachnoid hemorrhage. 2. loss of pharyngeal muscle control and gag reflex. 3. respiratory failure. 4. pneumonia. 5. urinary tract infection. discharge disposition: the patient was to be discharged to rehabilitation services. discharge instructions/followup: 1. the patient should continue on levaquin for an additional seven days after discharge. 2. the patient should continue with aggressive chest physical therapy and suctioning. 3. the patient should continue with tracheostomy and gastrojejunostomy tube. 4. the patient may need ventilator assistance depending on his tachypnea. 5. the patient was instructed to follow up with neurosurgery in two weeks with dr. (telephone number ). 6. the patient was also instructed to follow up with trauma surgery in one to two weeks (telephone number ). major surgical/invasive procedures performed: 1. status post tracheostomy. 2. status post open gastrojejunostomy tube placement. condition at discharge: the patient was discharged in stable condition. discharge status: the patient was to be discharged to rehabilitation services. medications on discharge: 1. heparin 5000 units subcutaneously twice per day. 2. lopressor 75 mg by mouth twice per day. 3. tylenol one to two weeks by mouth q.4-6h. 4. dulcolax suppositories once per day as needed. 5. levaquin 250-mg tablets three tablets for a total of 750 mg by mouth once per day (times seven days). 6. regular insulin sliding-scale (per the attached sheet). 7. roxicet as needed. , m.d. dictated by: medquist36 procedure: venous catheterization, not elsewhere classified continuous invasive mechanical ventilation for 96 consecutive hours or more insertion of endotracheal tube enteral infusion of concentrated nutritional substances percutaneous [endoscopic] gastrostomy [peg] arterial catheterization temporary tracheostomy closure of skin and subcutaneous tissue of other sites transfusion of packed cells diagnoses: urinary tract infection, site not specified diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled bacteremia accidental fall on or from other stairs or steps methicillin susceptible pneumonia due to staphylococcus aureus heart valve replaced by transplant subarachnoid hemorrhage following injury without mention of open intracranial wound, with brief [less than one hour] loss of consciousness other late effects of cerebrovascular disease, dysphagia 

Answer: The patient is high likely exposed to
