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 an 87 year old woman with a history of copd with two to three days of worsening confusion and worsening dyspnea. she denies cough, congestion or fever. she had sweats on the day prior to admission. sick contact positive for family member at home with a cough and temperature of 102. in the emergency department the patient had an arterial blood gas of 7.24/126/259. she had pulse oximetry saturation of 76% on 3 liters of o2. bipap was attempted, but the patient was unable to tolerate it. she was intubated and transferred to the medical intensive care unit. past medical history: chronic obstructive pulmonary disease on 2 to 3 liters of o2 at home. pfts in 7/98 showed fvc of 56%, fev1 49%, fev/fvc ratio 127% with decreased diffusing capacity. siadh. headaches. anxiety. rectal adenocarcinoma status post lower anterior resection in . medications: atrovent two puffs t.i.d., albuterol one puff b.i.d., propoxyphene (darvon) 65 mg t.i.d. p.r.n. headache, hydromorphone 1 mg b.i.d., klonopin 0.5 mg in a.m. and 1 mg in p.m., ranitidine 150 mg b.i.d., megace one teaspoon b.i.d., lactulose syrup one to three tablespoons b.i.d. social history: the patient states that she lives in in her house with seven children. quit smoking 20 years ago. physical examination: on admission temperature was 100.6, heart rate 96, blood pressure 157/63, oxygen saturation 97% on 2 liters. current physical exam temperature 99.1, pulse 93, blood pressure 140/80, oxygen saturation 94% on 3 liters. heent: oropharynx moist. chest: trace crackles at the left base, otherwise clear to auscultation bilaterally. cardiovascular regular rate and rhythm, normal s1, s2, no murmur. abdomen soft, nontender, nondistended, positive bowel sounds. extremities no edema. laboratory data: white blood cell count 18, hematocrit 41.4, platelets 307. sodium 136, potassium 4.3, chloride 84, co2 52, bun 12, creatinine 0.5. in 7/00 cardiac echo normal left ventricular systolic function, normal wall motion. on chest x-ray increased lung volume, flat diaphragm, infiltrates in lower lobe. on chest x-ray small bilateral pleural effusions with patchy consolidation of the left base. on white blood cells 13.8, hemoglobin and hematocrit 11.5 and 36.2, platelets 290. sodium 138, potassium 3.7, chloride 95, bicarbonate 36, bun 13, creatinine 0.5, glucose 113. calcium 8.6, phosphate 2.5, magnesium 1.8. arterial blood gas on 5 liters of o2 per minute was 7.38/59/98. on white blood cell count 13.5 (patient on steroids), hemoglobin and hematocrit 12.1 and 38.4, platelets 347. sodium 131, potassium 4.2, chloride 88, co2 40, bun 19, creatinine 0.5. hospital course: in short, this is a woman with chronic obstructive pulmonary disease exacerbated by pneumonia and intubated for respiratory failure. in the medical icu she was started on solu-medrol 40 mg iv t.i.d., atrovent and albuterol nebulizers. the patient's sputum showed gram negative rods and she was empirically started on ceftazidime. she received 2 gm of ceftaz, followed by 5 gm of 1 gm ceftriaxone iv q.24 hours and then was switched to 500 mg p.o. q.d. of levofloxacin on for a seven day course of levofloxacin. she was not febrile during this admission. she was still complaining of an occasional cough. ventilator dependence was minimal and she was extubated without complications on . intravenous steroids were stopped on and she was started on prednisone taper 60 mg q.d. on day of discharge, , it was the first day of prednisone 30 mg q.d. she was on 2 liters of nasal prong oxygen at home and this is what she was receiving at discharge. the patient was often confused, belligerent and anxious, but this apparently is her baseline. she complained of occasional headache. she has a history of chronic headaches for which she receives darvon (propoxyphene) 65 mg q.four hours p.r.n. and this was restarted. on discharge the patient had crackles to 1/3 up the lungs, but she did not have rales nor stigmata of congestive heart failure. given her pneumonia, these crackles make take a fair amount of time to resolve even if the active infection has already cleared. regarding her labs, sodium was around 130. she has a history of siadh secondary to lung disease and at times in the past has been on oral salt tablets 500 mg three times a day. because her sodium has been stable here off sodium tablets, they were not restarted. co2 was high at around 40, but looking at her past discharge summaries, this appears to be her baseline. she is likely co2 retaining from copd. discharge medications: 1. levofloxacin 500 mg p.o. q.d., last dose . 2. darvon (propoxyphene) 65 mg p.o. q.four p.r.n. headache. 3. colace 100 mg p.o. b.i.d. 4. klonopin 0.5 mg in a.m., 1 mg in p.m. 5. ranitidine 150 mg p.o. b.i.d. 6. lactulose syrup one to three tablespoons b.i.d. p.r.n. constipation. 7. atrovent inhaler two puffs t.i.d. 8. albuterol inhaler one puff b.i.d. 9. prednisone taper to 9/36 30 mg p.o. q.d., to 20 mg p.o. q.d., to 10 mg p.o. q.d., to 5 mg p.o. q.d., off prednisone. condition on discharge: stable. discharge status: the patient is a full code. disposition: to manor for rehabilitation. discharge diagnoses: 1. chronic obstructive pulmonary disease exacerbation. 2. pneumonia. the patient was being followed in the hospital by dr. , who is also her primary care physician. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours non-invasive mechanical ventilation diagnoses: pneumonia, organism unspecified congestive heart failure, unspecified obstructive chronic bronchitis with (acute) exacerbation anxiety state, unspecified osteoporosis, unspecified personal history of malignant neoplasm of large intestine 

Answer: The patient is high likely exposed to
