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: mercury,ammoniated / shellfish / cefepime attending: chief complaint: nausea, vomiting, diarrhea, syncope major surgical or invasive procedure: central line and arterial line placement history of present illness: -year-old woman with history of alzheimer's, oa, osteopenia, prior c. diff infection presented from home with multiple episodes of nausea, vomiting, loose stools, syncope. according to her son who lives with her, patient had been doing well with no complaints, attending her regular daycare program yesterday. she got home, helped her son dinner, ate dinner, went to bed. at around 7 pm, she woke up, went to the bathroom, had loose stools, vomited, and syncopized onto the bathroom floor for a very brief period of time. son helped her move back to bed. shortly afterwards he heard her falling on the bedroom floor. she was unresponsive for about 30 seconds and when she came back, reporting that she was feeling the need to go to the bathroom again but felt dizzy and fell. back to bed. shortly later, her son then found her vomiting in bed while lying on her bed, choking on her vomitus. the son turned her on her side. she was not very responsive at this time. the son called 911. . at baseline patient usually has "runny nose" per son with some mild, mostly nonproductive coughs. last night she was noted to have productive coughs. no subjective or objective fever at home. . in the ed, initial vs: t 98, hr 80, bp 142/70, rr 20, 95%ra. her head and neck ct was negative. cxr showed atelectasis vs. lll pna. cardiac enzymes were not elevated, and ecg showed no acute st/t changes. her lipase was elvated at 188, and patient underwent an abdominal/pelvic ct that was unremarkable. during the ed car, she became tachy to the 120s, rigoring, spiking to 101.7. her lactate was 3.4 after 2l fluid. she received vancomycin 1 gm iv x 1, levofloxacin 750 mg iv x 1. before being transferred to the micu, her vitals were t 101, hr 120, bp 122/76, rr 18, 95-98% 2l. past medical history: -

(vancomycin po was added for c diff prophylaxis given hx of such. she will need to continue this for 2 weeks after antibiotics complete.) she was initially hypotensive and required ivf resuscitation as well as pressors for ~4 hours. subsequently she was normotensive. sputum, blood, and urine cx were negative. she recieved vanc and zosyn in the icu which was changed to levofloxacin and flagyl on the medical floor. she was discharged on levo/flagyl and po vanc. # acute kidney injury: creatinine bumped to 1.3 on admission, improved to baseline after fluid resusucitation. # alzheimer's: donepezil, mirtazapine, and memantine were continued. # gastroenteritis: patient with improving diarrhea in house. likely her aspiration pneumonia related to emesis in the setting of a gastroenteritis. she was c. diff negative x2. her diarrhea improved on the medical floor although was still present at the time of discharge. however patient was taking in good pos and not getting dehydrated. # dispo: patient was seen by physical therapy and was cleared for home with 24 hour care which can be provided by family. patient will schedule with her pcp. medications on admission: medications (at home): calcitonin 200 units/spray 1 spray in alternate nostrils daily donepezil 10 mg qhs memantine 10 mg mirtazapine 15 mg qday calcium + d3 mvi omega 3 discharge medications: 1. donepezil 5 mg tablet sig: two (2) tablet po hs (at bedtime). 2. calcitonin (salmon) 200 unit/actuation aerosol, spray sig: one (1) spray nasal once a day: alternate nostrils daily. 3. memantine 5 mg tablet sig: two (2) tablet po qhs (). 4. mirtazapine 15 mg tablet sig: one (1) tablet po hs (at bedtime). 5. calcium carbonate 500 mg tablet, chewable sig: one (1) tablet, chewable po bid (2 times a day). 6. cholecalciferol (vitamin d3) 400 unit tablet sig: two (2) tablet po daily (daily). 7. multivitamin tablet sig: one (1) tablet po daily (daily). 8. levofloxacin 500 mg tablet sig: one (1) tablet po q24h (every 24 hours) for 4 days. disp:*4 tablet(s)* refills:*0* 9. metronidazole 500 mg tablet sig: one (1) tablet po q8h (every 8 hours) for 4 days. disp:*12 tablet(s)* refills:*0* 10. vancomycin 125 mg capsule sig: one (1) capsule po q6h (every 6 hours): take 4 times a day for next 4 days. when done with levofloxacin take 2 times a day for two weeks. disp:*44 capsule(s)* refills:*0* 11. imodium a-d 2 mg tablet sig: one (1) tablet po once a day as needed for constipation for 1 weeks. disp:*7 tablet(s)* refills:*0* 12. guaifenesin 50 mg/5 ml liquid sig: one (1) po every hours as needed for cough for 2 weeks. disp:*1 bottle* refills:*0* discharge disposition: home with service facility: vna discharge diagnosis: viral gastroenteritis aspiration pneumonia dementia secondary: c. diff discharge condition: mental status: confused - sometimes level of consciousness: alert and interactive activity status: ambulatory - independent discharge instructions: you were admitted to the hospital because of nausea, vomiting and diarrhea. we determined that you developed a pneumonia in the setting of vomiting. you were treated in the intensive care unit initially and improved and were sent to a medical floor. on the floor you improved and were able to switch to oral antibiotics. because of your history of c. diff infections you were given oral vancomycin while on other antibiotics. you will need to take the vancomycin as directed below. you were seen by physical therapy who felt it was safe for you to go home given your attentive family. please be very careful when walking and always have a family member present. medication changes: levofloxacin 500mg for 4 more days flagyl 500mg three times a day for 4 more days vancomycin capsules 125mg four times a day for 4 more days and twice a day for two weeks. followup instructions: please call gerontology office at to schedule an appointment with your pcp. procedure: venous catheterization, not elsewhere classified arterial catheterization diagnoses: anemia, unspecified acute kidney failure, unspecified unspecified septicemia severe sepsis depressive disorder, not elsewhere classified pneumonitis due to inhalation of food or vomitus septic shock alzheimer's disease dementia in conditions classified elsewhere without behavioral disturbance syncope and collapse disorder of bone and cartilage, unspecified intestinal infection due to other organism, not elsewhere classified
