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: codeine / vicodin attending: chief complaint: right arm pain major surgical or invasive procedure: incision & drainage, irrigation & debridement, vac dressing placement, right upper extremity right arm washout and i&d, vac dressing history of present illness: 40 yo m with h/o drug use who presents with 7 days of progressive arm pain and drainage. he originally injected himself im in the right arm with percocet. 5 days ago he became febrile to 102 and began noticing purulent discharge from the drainage site. he self-lanced this wound with a straight razor 3 days prior to presentation. he awoke this morning with severely increased arm pain, swelling, and new redness and is here seeking care. he reports emesis today, denies cp/sob/n/d. ed course: patient febrile, in significant pain. cbc with elevated wbc. bc pnd. ct scan (wet read) with evidence of necrotizing fascitis throughout right forearm up to humeral epiphysis, hyperdensity in medial aspect of upper arm consistent with needle end. past medical history: ivdu social history: previous drug user (cocaine, injected), denies drug use in past 3 years. previous etoh. disabled, married. family history: noncontributory physical exam: nad, a/ox3 ctab rrr soft wwp, rue - vac in place, distal pulses intact, no erythema/drainage pertinent results: imaging data: ct findings: diffuse edema within the soft tissues of the forearm and upper arm with a soft tissue defect noted along the radial aspect of the mid forearm. there is tracking soft tissue gas along the deep fascial intramuscular planes as well as edema which extends from the distal radius proximally to the level of the mid humerus. findings are compatible with necrotizing fasciitis. a linear metallic foreign body measuring approximately 11 mm in length is embedded within the biceps muscle and is seen on series 7, image 95 and 96. it is likely that this foreign body is not related to the acute process. the bones appear unremarkable with normal bony mineralization and no cortical destruction, or erosive changes to suggest osteomyelitis. given that iv contrast was not administered, the evaluation for fluid collections is limited. . impression: extensive subcutaneous and deep fascial edema with gas tracking along the deep fascial planes compatible with necrotizing fasciitis. the extent of involvement is detailed above, though extends from the level of the distal humerus through the level of the distal radius. small retained foreign body embedded within the biceps muscle as detailed. no evidence of osteomyelitis. brief hospital course: the patient was admitted to the acute care surgical service on for evaluation and treatment of necrotizing fasciitis. admission rue ct revealed subcutaneous and deep fascial edema with gas tracking along the deep fascial planes compatible with necrotizing fasciitis extending from the level of the distal humerus through the level of the distal radius with fevers to 105 and leukocytosis to 17,000. the patient underwent open debridement and vac dressing placement, which went well without complication (reader referred to the operative note for details). the patient was hemodynamically stable. following a second debridement procedure, the patient returned to the operating room for split thickness skin graft placement with vac dressing by the plastics and reconstructive surgery service, monitored and subsequently discharged. . id: the patient's white blood count and fever curves were closely watched for signs of infection. the patient was started empirically on vancoymcin, zosyn, and clindamycin. wound care - pt required two debridement procedures and vac dressing placement. surgical sites were routinely monitored for signs of infection. . endocrine: the patient's blood sugar was monitored throughout his stay; insulin dosing was adjusted accordingly. . hematology: the patient's complete blood count was examined routinely; no transfusions were required. . pain was well controlled. diet was progressively advanced as tolerated to a regular diet with good tolerance. the patient voided without problem. during this hospitalization, the patient ambulated early and frequently, was adherent with respiratory toilet and incentive spirometry, and actively participated in the plan of care. the patient received subcutaneous heparin and venodyne boots were used during this stay. . at the time of discharge, the patient was doing well, afebrile with stable vital signs. the patient was tolerating a regular diet, ambulating, voiding without assistance, and pain was well controlled. the patient was discharged home with vna services for dressing changes. the patient received discharge teaching and follow-up instructions with understanding verbalized and agreement with the discharge plan. medications on admission: neurontin, trileptil, trazodone discharge medications: 1. percocet 5-325 mg tablet sig: 1-2 tablets po every 4-6 hours for 2 weeks: do not drive, operate machinery, or take tylenol while on this medication. disp:*75 tablet(s)* refills:*0* 2. clindamycin hcl 300 mg capsule sig: 1.5 capsules po every 6 hours daily for 2 weeks followed by twice daily for 2 weeks for 1 months: 475mg po q6 for 2 weeks followed by 500mg po bid for 2 weeks. disp:*120 capsule(s)* refills:*0* discharge disposition: home discharge diagnosis: necrotizing soft tissue infection right forearm discharge condition: mental status: clear and coherent. level of consciousness: alert and interactive. activity status: ambulatory - independent. discharge instructions: you were admitted to the hopsital with a sever skin infection in your right arm. the infection required several operations and use of special dressing devices. you were seen and evlauted by infectious disease and were given intravenous antibiotics. you should avoid injections of any substances into your bloodstream and skin. if you have been prescribed narcotics for pain control these medications should be taken only as directed by mouth. do not take illicit drugs, drink alcohol, drive or operate heavy machninery while on these types of medications. followup instructions: follow up with plastic surgery clinic in 1 week. call for an appointment. procedure: excision of lesion of other soft tissue other incision of soft tissue of hand diagnoses: chronic hepatitis c without mention of hepatic coma hyposmolality and/or hyponatremia epilepsy, unspecified, without mention of intractable epilepsy cocaine dependence, unspecified necrotizing fasciitis 

Answer: The patient is high likely exposed to
