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 77 year-old man with a history of mild emphysema and hypertension transferred from an outside hospital after an exacerbation of chronic obstructive pulmonary disease. the patient was reportedly not feeling well and awoke feeling fatigued and short of breath at rest. over the course of the following three days the patient became more short of breath and then had decreased po intake. at that time the patient had no cough, fever or paroxysmal nocturnal dyspnea, orthopnea or congestion on the day of admission. he was seen by his primary medical doctor and noted to be tachypneic and hypoxic. he was noted to have an o2 saturation of 70% on room air. he was advised to go to the emergency department and on arrival he had a respiratory rate of 32 and was satting in the 97% range on 100% nonrebreather mask. the patient had a white blood cell count of 17 at the outside hospital and arterial blood gas, which showed a gas of 7.16, 90, 67. the patient became progressively more hypoxic to 87 on 100% nonrebreather and the patient was intubated and noted to have thick yellow secretions following intubation. he received combivent and methylprednisolone, lasix and levofloxacin at the outside hospital. he was then transferred to the micu for further definitive care. micu course: the patient's respiratory status improved over the course of the micu stay. his fio2 was weaned. he was 50% on the second day of the stay. his arterial blood gas improved to 7.30/59/94 and he remained hemodynamically stable throughout. he was continued on steroids and nebulizers and antibiotics. he was also continued to have copious amounts of sputum and desatted occasionally, but corrected with suction. the patient ruled out for myocardial infarction given some initial t wave changes. he failed extubation initially, but was finally extubated on and has done well since. he is transferred to the floor for further follow up. he currently has a nonproductive cough and states that he feels like he has to cough something up. he was slightly short of breath and describes a sick feeling, short of breath after running. he has no chest pain, palpitations and no chills. past medical history: 1. hypertension. 2. emphysema. 3. hypercholesterolemia. 4. gout. 5. chronic renal insufficiency. 6. myelodysplasia anemia. 7. cerebrovascular accident. medications: 1. lisinopril 40 q day. 2. atenolol 25 q day. 3. procardia 60 q day. 4. allopurinol 300. 5. aspirin 81 mg. 6. lipitor 40 q day. allergies: no known drug allergies. social history: significant smoking history, 60 pack years. no significant drinking or intravenous drug use. he lives ni with his wife and is retired from the tobacco industry. physical examination: vital signs were 97.3, pulse 86, blood pressure 160/70, respirations 22 and he was satting 95% on 3 liters nasal cannula. in general the patient was sitting upright in the chair with arms first in a tripod and then over the table. he was in no acute distress and appeared somewhat comfortable. heent examination pupils are equal, round and reactive to light. extraocular movements intact bilaterally. mucous membranes are moist. neck trachea was midline. there was no jvd noted. pulmonary examination he had positive wheezes in the middle and upper lobes bilaterally. no crackles or rhonchi and he had slight accessory muscle use as well. cardiovascular examination regular rate and rhythm. no murmurs, rubs or gallops. his abdominal examination was good bowel sounds, nontender, nondistended. no hepatosplenomegaly. no masses appreciated. extremities were warm and well perfuse throughout. no clubbing, cyanosis or edema. he had 2+ dorsalis pedis pulses and radial pulses bilaterally. neurological examination was no focal deficits. cranial nerves intact throughout. laboratory examination: he had a white blood cell count of 19.8, hematocrit 34.3, platelets 359 and an mcv of 102. sodium 148, potassium 4.5, chloride 110, bicarb 30, bun 73, creatinine 2.2, glucose 107, calcium 9.1, phosphate 4.4, magnesium 2.4. his initial electrocardiogram showed a normal sinus rhythm with right axis deviation and some flattening in the precordial leads with a possible right bundle branch, but no acute changes when compared. chest x-ray was negative except for some minor small bilateral pleural effusions. assessment/plan: this is a 77 year-old man with chronic obstructive pulmonary disease flare likely secondary to a upper respiratory infection or pneumonia. the patient continued to do well on the floor, but was satting well on 3 liters nasal cannula. he was continued on steroids and switched to prednisone to be tapered in two to three weeks. he was continued on his combivent q 3 to 4 hours prn and his sats were monitored q 4 to 6 hours. he was continued on his o2 cannula for sats to be kept at greater then 90 to 92%. given his chest x-ray at the outside hospital there was no evidence for infiltrate, but we continued levofloxacin given plan out to ten days. cardiovascular wise he was ruled out by enzymes times three. he was already on aspirin and a beta-blocker, but he was slightly hypertensive when he arrived to the floor. we continued to control his blood pressure with metoprolol and slowly reintroduced his home medications as needed to control his blood pressure. his renal function continued to improve and his creatinine dropped from a initial value of 2.2 back to his baseline. he was discharged again on his levofloxacin for two more days to finish a ten day course and he was continued on his prednisone on an outpatient basis to be tapered every three days as detailed on his discharge summary. he was continued on fluticasone and he desatted with physical therapy prior to discharge to the high 80s and was felt to benefit from home o2, so was discharged on 2 to 3 liters home o2. physical therapy felt he would benefit from some physical therapy. we called his primary care physician and discussed options for physical therapy on and she stated that she would look into either a cardiac physical therapy at his home hospital or some pulmonary therapy across at . this instructions to make an appointment with a pulmonologist of his choice in three to four weeks and to have follow up pulmonary function tests in one to two months after calming of his chronic obstructive pulmonary disease flare. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours diagnoses: anemia, unspecified pure hypercholesterolemia unspecified essential hypertension acute kidney failure, unspecified obstructive chronic bronchitis with (acute) exacerbation acute respiratory failure 

Answer: The patient is high likely exposed to
