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: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: respiratory distress major surgical or invasive procedure: none history of present illness: the patient is a 79 year old gentleman with a pmh significant for htn, afib, and squamous cell lung ca diagnosed in , status post right upper lobe lobectomy, who presented to the ed with c/o left back pain. the patient first reported back pain starting on , with no radiation, and which came on after coughing. he has also complains of worsening sob for the last few days and increased productive cough. denies chest pain, n/v, f/c. on arrival to ed, he was afebrile, and vitals were stable with 97% o2 on 2 l, bp 162/74. in the ed, the patient went to the restroom and became diaphoretic and hypertensive upon standing with bp's increased to 206/79. he also had increased sob, decreased o2 sats to 73% and was more lethargic; abg at that time was - 7.23/101/72 (uncertain fio2). pt. was intubated; received nebs, solumedrol 80 iv, levoflox 500 iv x 1 and 10 mg iv hydralazine. ce's were negative x 1, ekg demonstrated old lbbb, and hct was 26 (baseline 30-31). initial cxr demonstrated new bilateral nodular opacities, old r pleural effusion, and r 5th rib fracture. repeat cxr following onset of symptoms demonstrated complete opacification of the r.lung field. a 3rd cxr following tx. demonstrated interval resolution of this opacification. repeat abg: 7.34 / 61 / 348. the patient was admitted to the for further mangagement. past medical history: 1. squamous cell lung carcinoma, status post right upper lobe lobectomy; on last hospitalization () ct and mri demonstrated a right skull-base lesion worrisome for metastatic bone dx, but f/u bone scan did not reveal evidence of metastatic dx. 2. seizure- one seizure 15 years ago, previously on subtherapeutic dilantin which was discontinued in ; recent seizure in for which he was hospitalized and started on keppra. 3. mitral valve replacement, known ejection fraction of 35 to 40%; 4. chronic obstructive pulmonary disease on home oxygen therapy intermittently 5. hypertension 6. atrial fibrillation 7. hypercholesterolemia 8. osteoarthritis 9. history of lef tibial osteomyelitis 10. history of gastrointestinal bleed in . social history: the patient has a ten year pack history, quit 30 years ago. no recent alcohol use. distant history of drinking up to eight beers per day. he lives with his son and wife. w/ a cane at home. physical exam: triage vitals: temp 97, hr 94, bp 162/74, rr 20, 97%o2 sats on 2l via nc vitals on admission to icu: temp 93.9 hr 66, bp 121/41, 97%o2 on ac fio2 49%, peep 5, rr 12 (breathing at 16). gen- intubated, unresponsive to commands or sternal rub. heent- pupils 3-->2 bilat. jvp at 7cm cv- irreg, irreg. rusb systolic murmur, no radiation to carotids. strong s2. no rubs/ gallops pulm- coarse ronchi mid to base r>l. breath sounds present bilat., but decreased on r;
