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. is an 88-year-old gentleman transferred to this hospital. he had sustained a fall on the , and he was admitted to the for evaluation of syncope. he was ruled out for myocardial infarction during his admission. two days after his fall, they noticed that his right upper extremity was weak, and they noted some alteration in mental status, where he was confused and was refusing to swallow properly and was difficult to awaken. therefore a head ct was done, which showed a large right subdural collection with mixed new and old blood. the neurosurgery team at was , and mr. was transferred to the neurosurgical intensive care unit in this hospital for burr hole vs. a craniotomy and evacuation of the left subdural hematoma. he has had no history of being on anticoagulants or anti-platelet therapy. the family gives a history of multiple falls in the recent past, and also significant orthostatic hypotension leading to many of these falls. physical examination: the patient is sleepy but responds to voice, and he attempts to talk in mandarin. the pupils, left is post-surgical, and the right reacts to light. it is difficult to assess the cranial nerves as the patient was not really cooperative at this stage. he had bilateral conjunctivitis. the left arm was full strength, was , and the right upper extremity had no response to pain. the left lower extremity was , and the right lower extremity withdraws briskly to pain, but there was paucity of movement in the right lower extremity. the plantars were upgoing bilaterally. respiratory: air entry was equal bilaterally, with no wheeze or crepitations. cardiac: heart was regular rate and rhythm, heart sounds heard. past medical history: significant for hypertension. allergies: no known drug allergies. medications: norvasc, meclizine. assessment and plan: this is an 88-year-old hypertensive with a left subdural hematoma and right-sided hemiparesis. the plan was to load him with dilantin 1 gram intravenously, followed by maintenance of 100 mg three times a day, and to prepare him for surgery. hospital course: details of the surgery can be found in the operative note. he had a mini-craniotomy and the subdural was evacuated. the patient was sleepy in the immediate postoperative period. therefore, the endotracheal tube was left in situ to assist with ventilation. he was extubated 48 hours post-surgery. at that time, the weakness of the right upper extremity had improved to a great extent, and it was about +/5. the patient was transferred to the neurosurgical floor from the intensive care unit on the , where his vitals were stable. he was awake, alert, oriented when somebody who could speak mandarin was with him, but he had occasional episodes of waxing and levels of consciousness and some agitative spells. he received aggressive chest physiotherapy, but both the bedside and the video oropharyngeal swallow study were unsuccessful, and the patient could not be fed orally. therefore a percutaneous endoscopic gastrostomy tube was placed on the by the interventional radiology team. some amount of bloody aspirate was obtained from this, so therefore the tube was not used for the next 48 hours, but the patient's hematocrit remained stable, and therefore tube feeds were started and advanced to goal. during his stay in the neurosurgical floor, he also developed a temperature to 101. a chest x-ray revealed bilateral basilar atelectasis. the sputum showed mixed oropharyngeal flora. blood cultures were negative, and urine culture showed no growth. he was started on levaquin 500 mg as a first dose and 250 mg by mouth once daily for the next five days. his hematocrit on the was 32.8, white cells 10.7, platelets 180, inr 1.1, pt 12.8, ptt 30.1. his sodium was 137, potassium 3.8, chloride 101, bicarbonate 28, bun 15, creatinine .7, glucose 143. liver function tests were fine, with a total bilirubin of .5. he did not rule in for a myocardial infarction in this hospital. his dilantin level on the were 17.9, and another level is pending tomorrow. condition at discharge: mr. is awake, alert and oriented, and attempts to converse both in english and in mandarin. his left upper extremity and lower extremity are full strength, and he moves them freely. the right upper extremity is 4+/5, and he moves it spontaneously. the right lower extremity is also full strength. the patient cannot have anything orally, as he has failed the video oropharyngeal swallow study performed yesterday. he is being transferred to a rehabilitation facility tomorrow, on the . condition at discharge is stable. post-discharge plan: the patient is to follow up with dr. in three weeks' time, and a repeat head ct without contrast needs to be performed prior to his appointment with dr. . , m.d. dictated by: medquist36 procedure: incision of cerebral meninges enteral infusion of concentrated nutritional substances percutaneous [endoscopic] gastrojejunostomy diagnoses: unspecified essential hypertension unspecified fall pulmonary collapse subdural hemorrhage following injury without mention of open intracranial wound, unspecified state of consciousness
