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 59-year-old female with a history of hypothyroidism, hypertension, and glucose intolerance who presented to the emergency department with a cough. the patient was in her usual state of health until three days prior to admission when she began experiencing a "cold." she improved two days prior to admission. on the day prior to admission developed coughing, sweating, mild shortness of breath, and some weakness. she denied chest pain, palpitations, and leg swelling. she denied any travel. in the emergency department, the patient was noted to be febrile to 101, hypoxic with an arterial blood gas of 7.49/33/71 on nonrebreather. she was started on levofloxacin, intravenous fluids, and ceftriaxone and was transferred to the unit. past medical history: 1. hypothyroidism. 2. hypertension. 3. glucose intolerance. 4. grave's disease; status post ablation. allergies: no known drug allergies. medications on admission: (home medications included) 1. levoxyl 100 mcg p.o. q.d. 2. diltiazem-cd 300 mg p.o. once per day. social history: the patient works with children and lives at home with her husband. she denies tobacco, ethanol, and drugs. physical examination on presentation: on admission, temperature was 101.7, blood pressure was 146/71, heart rate was 116, and oxygen saturation was 97% on 100% nonrebreather. in general, the patient was a pleasant female in no acute distress. sclerae were anicteric. the oropharynx was clear. no jugular venous distention. cardiovascular examination revealed tachycardia with normal first heart sounds and second heart sounds. pulmonary examination revealed decreased breath sounds at the left base. the abdomen was soft, nontender, and nondistended. positive bowel sounds. no hepatosplenomegaly. extremity examination revealed no clubbing, cyanosis, or edema. no calf tenderness. neurologic examination revealed awake and oriented times three and mentating well. pertinent laboratory values on presentation: on admission, white blood cell count was 8.2, hematocrit was 36, and platelets were 332. differential with 67 bands, 5 lymphocytes, and 4 monocytes. electrolytes revealed sodium was 134, potassium was 3.5, chloride was 92, bicarbonate was 24, blood urea nitrogen was 17, creatinine was 0.9, and blood glucose was 112. pertinent radiology/imaging: a chest x-ray showed a left lower lobar pneumonia and effusion with layering. electrocardiogram revealed tachycardia at 115 with left atrial enlargement. there were st depressions laterally; consistent with risk of ischemia versus hypertensive repolarization. these were new compared to . hospital course: the patient was admitted to the unit. she was continued on antibiotics. respiratory culture returned showing beta streptococcus group a (heavy growth). blood cultures from the day of admission also returned with group a streptococcus. she was continued on penicillin while in the unit. her oxygen requirement improved; however, her white blood cell count three days after admission continued to trend up. she was transferred to the floor. at this point, she was started on clindamycin and infectious disease was consulted. her white blood cell count trended down to 10.1 on the day of discharge. after beginning clindamycin, she became afebrile and maintained this as well until the time of discharge. two days prior to discharge, the patient complained of increased pain in her right knee. the knee was tapped. this showed a white count of 167, red blood cells of 64,000, 42 polys, 37 lymphocytes, and 17 monocytes. it was felt this was likely due to a bursitis. the gram stain showed pml and no microorganisms. blood culture preliminarily showed no growth two days after obtaining fluid. the knee felt better after the tap and remained without effusions until the time of discharge. this was to be followed up on an outpatient basis. electrocardiogram changes resolved during her hospital course. discharge status: the patient was discharged to home. discharge diagnoses: 1. left lower lobar pneumonia. 2. bacteremia with group a streptococcus. discharge instructions/followup: the patient was to follow up with dr. on . medications on discharge: 1. diltiazem 300 mg p.o. once per day 2. metoprolol 25 mg p.o. twice per day. 3. aspirin 81 mg p.o. once per day. 4. albuterol/ipratropium 1 to 2 puffs inhaled q.6h. 5. levothyroxine 100 mcg p.o. once per day. 6. penicillin v 250 mg p.o. q.6h. , m.d. dictated by: medquist36 procedure: thoracentesis arthrocentesis diagnoses: abnormal coagulation profile unspecified pleural effusion unspecified essential hypertension bacteremia other postablative hypothyroidism pneumonia due to streptococcus, group a streptococcus infection in conditions classified elsewhere and of unspecified site, streptococcus, group a enthesopathy of knee, unspecified 

Answer: The patient is high likely exposed to
