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 a 55-year-old female with non-hodgkin lymphoma, status post chemotherapy treatment with fludarabine one month ago who presents with sore throat and throat swelling since this morning. no fever or chills. no shortness of breath. no cough. no rhinorrhea. daughter has had mononucleosis three weeks ago. in the emergency room the patient was scoped by ent. she was found to have supraglottic watery edema including epiglottic fold and false cords. a 1-cm area was noted with adenoid hypertrophy. she was given solu-medrol, unasyn intravenously, zantac intravenously. anesthesia and surgery were consulted in the emergency room concerning management. past medical history: non-hodgkin lymphoma diagnosed in , status post chop, in remission for 12 years, recurred in , status post fludarabine. the patient's oncologist is dr. . medications on admission: none. allergies: no known drug allergies. social history: lives with family. no tobacco use. no ethanol use. physical examination on admission: vitals revealed a temperature of 98.1, heart rate 86, blood pressure 123/65, oxygen saturation 97% on room air. this is a pleasant female in no acute distress. no stridor. heent revealed pupils were equal, round, and reactive to light. the oropharynx was clear. the chest was clear to auscultation bilaterally. heart had a regular rate and rhythm, s1/s2. no murmurs. abdomen was soft, nontender, and nondistended. extremities had no swelling or tenderness. neurologically, alert, awake, and oriented; grossly intact. laboratory data on admission: white blood cell count 6.2, hematocrit of 36.5, platelets 220. sodium 140, potassium 3.9, chloride 103, bicarbonate 23, bun 18, creatinine 0.6, glucose 132. calcium 8.8, magnesium 1.9, phosphate 3.9, ldh 192, uric acid 4.9. hospital course: this is a 55-year-old woman with recurrent non-hodgkin lymphoma presenting with airway edema, but no stridor compromise. the patient was admitted to the medical intensive care unit. in the medical intensive care unit the patient received decadron 10 mg intravenously q.8.h., zantac 50 mg intravenously q.8.h., unasyn 3 g intravenously q.6h., and humidified oxygen. ent was consulted and agreed with steroid course. over the course of the hospital the patient improved and was seen by oncology. oncology believed that the patient had no significant nodal disease in the neck, and therefore cancerous cause of the throat swelling was unlikely, although still a possibility. the most likely cause was either an acute viral or bacterial pharyngitis or epiglottitis and agreed with steroid and antibiotic use and continuous oxygen monitoring. chest x-ray showed normal findings. no lung disease. the patient was not intubated over the course of her hospitalization. by the patient had improved significantly and was discharged. medications on discharge: bactrim, acyclovir, and augmentin. discharge followup: recommended follow up with oncology in four to six weeks. condition at discharge: good. discharge status: stable. discharge diagnoses: supraglottic edema and stenosis. mark , m.d. dictated by: medquist36 procedure: laryngoscopy and other tracheoscopy laryngoscopy and other tracheoscopy diagnoses: other malignant lymphomas, unspecified site, extranodal and solid organ sites edema of larynx acute epiglottitis with obstruction hypertrophy of adenoids alone 

Answer: The patient is high likely exposed to
