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: an 85-year-old female with osteoporosis and legally blind who fell while walking with family in a mall. she had no precipitating symptoms, no head trauma or seizure activity but did lose consciousness for approximately 2 minutes. after the syncopal episode, she felt lightheaded and had a headache; 30 minutes later, she had a second syncopal episode. the patient became progressively agitated and confused over the next few hours. the patient was in and refused to go to the emergency room. they drove down from to emergency department for evaluation. on arrival to the emergency department, her vital signs were stable, but she quickly became hypoxic and hypotensive requiring intubation and pressors. a head ct showed an old right occipital infarct, and she had a negative cta and negative lumbar puncture. the patient had an elevated lactate, and also there was no clear source of infection. she was started on antibiotics. she was admitted to the intensive care unit. past medical history: legally blind. osteoporosis. right occipital stroke in . past surgical history: femoral hernia repair. medications: 1. aspirin. 2. fosamax. family history: liver cancer. social history: she lives at home with her daughter. tobacco or alcohol use. the patient walks with a cane at baseline. allergies: no known drug allergies. physical examination: on arrival to the icu, temperature 98.6 degrees, pulse 100, respiratory rate 18, blood pressure 97/51, saturation 100 percent. general, intubated, elderly thin female, sedated. heent, pupils 3 mm and sluggishly reactive. neck, no jvd, no carotid bruits. pulmonary, clear to auscultation anteriorly. cardiovascular, tachycardia, regular rhythm, and no murmurs. abdomen, soft, nontender, nondistended, normoactive bowel sounds. extremities, no clubbing, cyanosis, or edema; warm, 2 plus dorsalis pedis pulses bilaterally. skin, no stigmata of endocarditis noticed. laboratory data: significant labs at the time of icu admission, white count 7.5, 0 bands, bicarbonate 17, anion gap 10, negative ua, troponin 0.07, cpk 84, albumin 2.9, abg 7.21/39/442, lactate 5.2. radiographic studies: ekg, normal sinus rhythm at 100 beats per minute with normal axis and intervals; depressions in v5, v6, and i, new biphasic t-wave in v4 through v6 and i. a right upper quadrant ultrasound showed positive intrahepatic ductal dilatation with mild gallbladder wall thickening. chest x-ray showed no cardiopulmonary process with some apical scarring. ct of her head without contrast showed no hemorrhage, but an old right posterior infarct with chronic small-vessel ischemic changes and a possible 1.8 cm aneurysm in her ica. a cta showed no pulmonary emboli with small pleural effusions bilaterally, right greater than left, questionable ascites with some fluid around the pancreas. an x-ray of her right hand showed no fracture. hip x-ray showed no fracture. echocardiogram showed an ejection fraction greater than 55 percent with dilated right ventricle and some hypokinesis without any evidence of pericardial effusion. hospital course: an 85-year-old female who is status post syncope times 2, admitted with hypotension and hypoxia, requiring intubation, pressors, and antibiotics that completely resolved within 2 days. infectious disease. although the patient appeared septic upon presentation with an elevated lactate and hypotension, there was no clear evidence of infection. blood pressure improved and the patient was weaned off pressors after 1 night. there have been no source or other evidence of infection. therefore, antibiotics were discontinued. the patient did have multiple episodes of diarrhea but she was c. difficile negative. hypoxia. again, there was no clear etiology of the patient's hypoxia. she was extubated without difficulty and remained on room air for the rest of her hospitalization. syncope. the patient was kept on telemetry. however, there was no evidence of arrhythmia. a ct of her head showed no change and lumbar puncture was negative. she had normal carotid ultrasounds. an echocardiogram showed small right ventricular hypokinesis and dilation with tricuspid regurgitation. the patient was recommended to have an outpatient mra/mri to evaluate questionable aneurysm seen on ct scan. abnormal right upper quadrant ultrasound. the patient had mild transaminase with ductal dilatation and gallbladder wall thickening on right upper quadrant ultrasound. the patient's lfts trended downwards. the patient was recommended to have an outpatient mrcp to evaluate for stones in her common bile duct. disposition: the patient was discharged to home with services. condition on discharge: alert and oriented, full affect, presently walking with a cane and assistance, blood pressure and oxygen saturation are normal. discharge diagnoses: syncope of unknown etiology. hypotension. respiratory failure requiring intubation. transaminitis. history of cerebrovascular accident. osteoporosis. blindness. follow-up: recommended to follow up with her pcp within the next 1 to 2 weeks. plan: we recommend outpatient mri to evaluate questionable injuries as seen on the ct scan as well as an outpatient mrcp for elevated transaminitis and dilatation and thickening of the gallbladder. discharge medications: 1. aspirin 325 mg once a day. 2. multivitamin 1 capsule p.o. q.d. 3. fosamax 35 mg 1 tablet p.o. q.d. , procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours spinal tap incision of lung insertion of endotracheal tube diagnoses: acidosis acute respiratory failure hypotension, unspecified osteoporosis, unspecified diarrhea syncope and collapse legal blindness, as defined in u.s.a. nonspecific elevation of levels of transaminase or lactic acid dehydrogenase [ldh] 

Answer: The patient is high likely exposed to
