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 year-old woman with history of moderate af, paroxysmal atrial fibrillation, hypothyroidism, dementia and essential thrombocythemia who presents with shortness of breath and fever. the patient is a resident of who was in her usual state of health until approximately one week prior to admission when she noticed cough and cold like symptoms. these symptoms worsened over the following week. the cough productive of dark green sputum. she was seen by a physician at the three days prior to admission. at that time she was treated with nebulizers for presumed viral urinary tract infection. however, her condition continued to deteriorate. specifically, she became more short of breath, reduced exercise intolerance, worsening cough with productive sputum, and decreased exercise tolerance. she was brought to the for further evaluation. in the emergency department she was noted to be febrile to 102.3. chest x-ray showed possible right upper lobe pneumonia. the patient was treated with ceftriaxone and azithromycin. she was also noted to be in rapid atrial fibrillation and was started on a diltiazem drip. past medical history: 1) vertigo. 2) moderate aortic stenosis. 3) paroxysmal atrial fibrillation. 4) history of urinary tract infections. 5) hypothyroidism. 6) alzheimer's with multi-infarct dementia. 7) echocardiogram in at outside hospital showing normal left ventricular ejection fraction, mild diastolic dysfunction, calcified aorta, mild pulmonary hypertension, moderate aortic stenosis. allergies: question allergy to penicillin. medications: 30 mg b.i.d., flonase q.d., multivitamin, aricept 5 mg q day, hydroxyurea 500 mg q day, hydrocortisone cream, metoprolol 12.5 mg b.i.d., levoxyl 112 mcg q.d., coumadin 2.5 mg q.d., nizoral, dilantin, xalatan. social history: the patient has a very supportive family. she currently lives in and is capable of completing her anterior cruciate ligament without assistance. she walks with a walker. family history: noncontributory. admission laboratories: were notable for an inr of 4.6. her chem-7 was unremarkable. her urinalysis was negative for nitrates and leukocytes. cardiac enzymes were negative. chest x-ray: right upper lobe opacity consistent with possible pneumonia. no congestive heart failure noted. bibasilar atelectasis. ekg: atrial fibrillation with ventricular rate greater than 100. no st segment changes. hospital course: the patient was admitted to the medicine service for further evaluation. she was alert and oriented at time of admission. she was complaining of subjective shortness of breath and was breathing at a respiratory rate of approximately 20. she was saturating 85 to 95 percent on 2 liters by nasal cannula. she reported only minimal improvement to nebulizer treatment. she was febrile in the emergency department but remained afebrile on the floor. she was started on levofloxacin for treatment of her pneumonia. on day of admission the resident and intern were called to see the patient at approximately 2 p.m. for tachycardia and shortness of breath. the patient had been titrated off her diltiazem drip which had been started in the emergency department. she was maintained on metoprolol. at the time the intern and resident examined the patient she was satting 95 percent on 2 liters by nasal cannula. a repeat chest x-ray was unchanged from prior with no signs of congestive heart failure. it was felt that the patient was stable at this time. her elevated heart rate was transient and was treated by increasing her metoprolol dose. she was noted to be again in atrial fibrillation. then again at 7 p.m. the intern was called to see the patient for increased confusion. at that time the patient was noted to have labored breathing. a pulse oximeter measured her o2 saturation to be approximately 65. she was started on a nonrebreather. an arterial blood gases was obtained which showed a pco2 of 109, a po2 of 102, and a ph of 7.06. calculated sodium bicarb was 33 percent. the patient had a repeat chest x-ray obtained. this showed some mild congestive heart failure. the medical intensive care unit team was notified and the patient was transferred to the intensive care unit. the family was also notified. the patient's daughter stated that she wanted her mother to be dnr/dni. again the patient was supertherapeutic on coumadin with an inr of 4.6. she was reversed with vitamin k. patient's hydroxyurea therapy was discontinued while in the medical intensive care unit. she was started on cefepime, vancomycin and levofloxacin for treatment of her pneumonia. the patient was reversed with vitamin k and a picc line was placed. she continued to improve over the following days. her heart rate was controlled with intravenous metoprolol and/or lopressor. all cultures both blood and urine remained negative during her hospital course. the patient was transferred to the floor for further management on . the patient was transitioned to p.o. medications. speech and swallow evaluation was conducted which revealed that the patient tolerated thick and liquids well. she was continued on antibiotics for a ten day course. after discontinuing of her antibiotics the patient had increasing white blood cell count. she was also noted to have very mild low grade fevers and very minor change in mental status. patient was then restarted on antibiotics and the ct scan was obtained of her chest. the ct scan was relatively unremarkable but did show possible early pneumonia. the patient was continued on a seven day course of cefepime, vancomycin. upon completing this course the patient remained afebrile and remained alert and oriented. prior to discharge her mental status continued to improve. her course was also complicated by renal insufficiency with increase in her creatinine to 2.3 from a baseline of 0.7. this was felt to be due to a transient episode of hypotension. her creatinine began to improve again prior to discharge and was 1.8 at time of discharge. overall impression: this is a year-old female with a past medical history significant for central thrombocytosis, moderate atrial fibrillation and congestive heart failure. who presented with worsening shortness of breath and tachycardia. it was believed that the patient's pneumonia worsened her atrial fibrillation causing her to have an increase in heart rate. this in turn caused the patient to go into decompensated congestive heart failure requiring a medical intensive care unit stay with aggressive diuresis. the patient was treated for pneumonia with antibiotics. her course was complicated by an episode of renal insufficiency which was resolving by time of discharge. the patient was tolerating good p.o. intake and was cleared by speech and swallow on the day of discharge. condition on discharge: stable. discharge status: to rehabilitation. discharge diagnoses: 1. essential thrombocytosis off hydroxyurea. 2. congestive heart failure likely secondary to diastolic dysfunction in rapid atrial fibrillation. 3. pneumonia. 4. aortic stenosis. 5. atrial fibrillation.
