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: interferon alfacon-1 attending: chief complaint: post intubation tracheal stenosis, doe major surgical or invasive procedure: flexible bronchoscopy tracheal resection and reconstruction. history of present illness: mr. is a 51-year-old gentleman, transferred from , who had been intubated following treatment of his hepatitis c with interferon. he has had progressive worsening of dyspnea on exertion and progressive hoarseness. rigid bronchoscopy revealed a proximal tracheal stenosis in the a-frame shape suggestive of a stomal injury. past medical history: hep c, interstitial pneumonitis/resp.failure from peg-ifn, s/p trach/open j-tube placement, cirrhosis social history: +tob 38 yrs 1ppd quit etoh quit 20 yrs ago hx of cocaine use quit 5 yrs ago lives alone family history: non-contributory physical exam: gen: nad cv: rrr chest: cta bilaterally abd: soft, nt, obese ext: + pulses inc:cdi pertinent results: cardiac echo: conclusions: the left atrium is normal in size. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. overall left ventricular systolic function is mildly depressed with mild global hypokinesis more prominent in the mid to distal antero-lateral wall. there is no ventricular septal defect. right ventricular systolic function is borderline normal. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. the mitral valve leaflets are mildly thickened. mild (1+) mitral regurgitation is seen. the tricuspid valve leaflets are mildly thickened. there is no pericardial effusion. cxr : impression: slowly improving bilateral interstitial opacities, which may be due to resolving pulmonary edema, infection or hemorrhage. continued followup is recommended to exclude a more chronic interstitial abnormality. complete blood count wbc rbc hgb hct mcv mch mchc rdw plt ct 06:40am 8.9 3.84* 12.2* 34.6* 90 31.8 35.3* 15.6* 109 brief hospital course: pt was admitted w/ tracheal stenosis and bronchoscopy to identify extent of lesion. the bronchoscopy was complicated by flash pul edema requiring intubation and sicu admission. pt was diuresed and extubated to bipap on ppd#1/hd# 3. on hd# 5 pt was started on vanco/levo for persistant leukocytosis and sputum w/ gm+ cocci. transferred from icu to floor to await tracheal surgery. on hd#7 pt had bronchoscopy which showed stable stenosis. on hd# 13 pt was taken to the or for tracheal resection and reconstruction. guardian stitch placed in or to amintain neck flexion and to decrease tension on anastomosis. post operatively pt was admitted to the sicu for airway management. aps was following for pain management. extubated on pod#1. pod#3 pt transferred from icu to

Answer: The patient is high likely exposed to
