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: past medical history: 1. mantle cell lymphoma diagnosed in , status post xrt and chemotherapy, recently diagnosed with radiation pneumonitis, started on prednisone. this was complicated by herpes labialis. he is followed by from the dept. of heme/onc. 2. hypertension. 3. diabetes mellitus, currently diet-controlled. 4. atrial fibrillation, two episodes, always in the context of surgery. 5. diverticulosis with the previous gi bleed in . the patient had a sigmoidoscopy with no sources localized. 6. hypothyroidism. 7. status post turp. 8. status post appendectomy. medications at home: 1. protonix 40 q.d. 2. acyclovir 400 p.o. t.i.d. 3. bactrim double-strength monday, wednesday, and friday. 4. prednisone 60 q.d. 5. potassium chloride 20 mg p.o. q.d. 6. ambien 5 q.d. 7. aspirin 81 p.o. q.d. 8. synthroid 175 p.o. q.d. 9. captopril 50 t.i.d. 10. nifedipine 30 p.o. q.d. 11. demodex, unknown dose, q.o.d. allergies: the patient has no known drug allergies. social history: he is married. he is a retired aircraft engineer. smoked about 45 packs per year but quit about 15 years ago. no alcohol. family history: no history of colon cancer or diverticulosis. physical examination upon transfer to the medical floor: vital signs: temperature 98.4, heart rate 78, blood pressure 150/80, respiratory rate 20, saturating 93 on 2 liters. general: the patient was a comfortable gentleman in no acute distress. heent: no icterus. moist mucous membranes. neck: supple with no lymphadenopathy. no jvd. respiratory: good air movement. occasional wheezes. no crackles. cardiovascular: s1, s2, with no murmurs, rubs, or gallops. abdomen: soft, nontender, nondistended with normoactive bowel sounds. extremities: trace edema, 1+ pulses. laboratory data on transfer to the medical floor: white count 6.6, hematocrit 25.2, platelets 139,000. chem-7 142, 4.0, 109, 24, 28, 1.0. he had unremarkable lfts. hospital course: 1. gastrointestinal: a consultation with the gi service was obtained and given that there was no bleeding seen on angiography their recommendations were to proceed with colonoscopy. this was done and the colonoscopy revealed multiple diverticuli but no evidence of active gi bleed. we, therefore, obtained an upper gi, small bowel follow through which was completely unremarkable. his hematocrit in the meantime has stabilized even though he required a couple of additional units of packed red blood cells. he remained consistently stable above 29 and upon discharge was 32. he continued to have several guaiac positive bowel movements per day but no episodes of frank blood in his stool. of note, he had absolutely no episodes of hemodynamic instability. 2. pulmonary: the patient carries the diagnosis of radiation pneumonitis. he has been on almost four weeks of prednisone 60 mg p.o. q.d. apparently. the dose was changed currently to 40 mg p.o. q.d. and an appointment was made with the pulmonary service in which he will follow-up next week regarding his radiation pneumonitis. his 02 saturations on 2 liters was 93 and 94% and without oxygen would drop to 90-91. upon ambulation, however, his sats dropped to 84 and, therefore, the patient is being discharged on home oxygen. 3. hematology: the patient was closely followed by hematology/oncology regarding his mantle cell lymphoma. his therapy is apparently on hold given the radiation pneumonitis exacerbation. of note, platelets dropped from a baseline of about 350 to 115 upon admission and then to as low as 99. in the context of this, his bactrim was withheld. we also withheld his aspirin in the context of a gi bleed and decreasing platelets. discharge condition: stable. discharged to home with 02 and vna. discharge diagnosis: 1. lower gastrointestinal bleed, most likely from diverticulosis. 2. mantle cell lymphoma. 3. radiation pneumonitis. discharge medications: 1. protonix 40 p.o. q.d. 2. acyclovir 400 mg p.o. t.i.d. 3. synthroid 175 p.o. q.d. 4. captopril 50 t.i.d. 5. nifedipine 30 p.o. q.d. 6. k-dur 20 mg p.o. q.d. 7. flonase inhaler 110 micrograms b.i.d. 8. prednisone 40 q.d. , m.d. dictated by: medquist36 d: 02:37 t: 10:42 job#: procedure: colonoscopy arteriography of other intra-abdominal arteries diagnoses: unspecified essential hypertension acute posthemorrhagic anemia diabetes mellitus without mention of complication, type ii or unspecified type, not stated as uncontrolled unspecified acquired hypothyroidism atrial fibrillation personal history of tobacco use diverticulosis of colon with hemorrhage other malignant lymphomas, lymph nodes of multiple sites acute pulmonary manifestations due to radiation 

Answer: The patient is high likely exposed to
