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: the patient is a 47-year-old man recently admitted to with a perirectal abscess. he left the hospital against medical advice and presented to the on the date of admission for re-evaluation. while the patient initially wanted re-evaluation, he became increasingly agitated in the emergency department. received a total of 20 mg of haloperidol intravenously for sedation, 6 mg of ativan, 1 mg of cogentin, and was then briefly admitted to the medical intensive care unit for monitoring. he was then transferred to the medical service for further evaluation. of note prior to admission, the patient received two doses of vancomycin on , one dose of zosyn as well as one dose of levofloxacin. on the morning of admission, the patient received one dose of clindamycin. past medical history: 1. recurrent urinary tract infections and a urostomy. 2. had previously a right sacral decubital ulcer and underwent primary closure at the . 3. the patient had a dubious history of hiv and he had a test done recently, but did not have the results reported to him on this admission. western blotting confirmed that the patient had the hiv infection with a cd4 count is 20 and viral load is 203. 4. questionable history of hepatitis c. 5. spina bifida. 6. patient has a complicated psychiatric history, no definitive diagnosis has been made, however, he has had suicidal ideas in the past, and has had problems that have resolved largely on this admission. allergies: 1. latex. 2. morphine. 3. codeine. medications on presentation: 1. paxil 40 mg daily. 2. clonazepam 2 mg every 8 hours. 3. risperidone 3 mg once daily. 4. lithium 900 mg once daily. social history: significant for injection drug use, cocaine, marijuana, tobacco, and ethanol. patient is homeless. physical examination on presentation: temperature 100.8, heart rate 76, respiratory rate 18, blood pressure 100/60 (note that patient's blood pressure is typically 100 systolic and this does not represent an abnormal finding), oxygen saturation of 95% on room air. on presentation, physical examination was not performed. because of the patient's marked agitation, however, interval examination revealed a rather deep left buttock ulcer approximately 4 cm wide and 7 cm deep. it was not draining pus, however, there was minimal granulation tissue, therefore his physical examination is not normal. laboratory evaluation on presentation: white blood cell count 6.5, hematocrit 29.3, platelets 100, inr of 1.3. urinalysis was normal. chemistry panel was unremarkable as stated above. hiv testing confirmed infection, however, the patient was hcv negative, but he was infected with hbv previously. toxicology screen was negative. hospital course: 1. psychiatry: after his brief admission to the medical intensive care unit, the patient was transferred to the medical service, and over the course of several days became less agitated, behavior was well controlled. his psychiatric medications were titrated to risperidone 3 mg twice daily, clonazepam 2 mg every eight hours. he did not require further haloperidol for the duration of his hospital course. 2. buttock ulcer: in consultation with the general surgery service, the patient underwent a long course of wet-to-dry dressing changes for his wound with minimal improvement. likewise, he was on approximately a two week course of vancomycin and metronidazole upon presentation, though his antibiotics were discontinued because the patient remained afebrile for the duration of his hospital stay. on , plastic surgery consultation was requested for his nonhealing wound. the patient was then taken to the operating room several days later for debridement and primary closure. the patient received approximately four more days of vancomycin and metronidazole postoperatively. at the time of this dictation, the patient still had - drain in place with serosanguinous material draining. the patient's postoperative course was marked by the absence of fevers, however, there was some increased pain requiring titration of his pain medicines, while he is on a stable regimen of long-acting oxycodone. he required additional medicines for pain control. another complication of his postoperative stay was increasing nausea attributed to his increased demand for pain control, optimum relief of his nausea was achieved with benadryl by mouth and intravenously. 3. hiv: on this admission, the patient's infection was confirmed in consultation with the infectious disease service. the patient was started on bactrim prophylactically against pneumocystis carinii pneumonia. the decision to start high reactive antiretroviral therapy was deferred until the patient was discharged and can be assured a stable followup. discharge diagnoses: 1. acquired immunodeficiency syndrome. 2. nonhealing buttock ulcer status post primary closure. 3. hepatitis b infection. 4. spina bifida. the remainder of hospital course shall be dictated separately at the time of discharge. discharge med: bactrim ds 1 qd for pcp . , m.d. dictated by: medquist36 d: 08:31 t: 08:34 job#: procedure: venous catheterization, not elsewhere classified venous catheterization, not elsewhere classified reconstruction of eyelid with hair follicle graft other local excision or destruction of lesion or tissue of skin and subcutaneous tissue diagnoses: urinary tract infection, site not specified unspecified protein-calorie malnutrition other, mixed, or unspecified drug abuse, unspecified human immunodeficiency virus [hiv] disease cellulitis and abscess of leg, except foot drug withdrawal spina bifida without mention of hydrocephalus, unspecified region abscess of anal and rectal regions
