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: patient recorded as having no known allergies to drugs attending: chief complaint: s/p stab wound assault major surgical or invasive procedure: embolization of ?liver pseudoaneurysm history of present illness: 18 m s/p stabbing x1 with kitchen knife to abdomen in right axillary line; taken to an area hospital where noted with liver laceration on ct scan. transferred to for further care.. past medical history: denies family history: noncontributory pertinent results: 02:34pm hct-42.8 09:38am hct-42.9 05:42am hct-40.3 02:52am glucose-97 lactate-4.0* na+-143 k+-3.9 cl--99* tco2-22 02:52am hgb-16.4 calchct-49 02:45am asa-neg ethanol-102* acetmnphn-neg bnzodzpn-neg barbitrt-neg tricyclic-neg 02:45am wbc-18.7* rbc-4.77 hgb-14.9 hct-45.2 mcv-95 mch-31.2 mchc-33.0 rdw-12.9 02:45am plt count-244 02:45am pt-13.6* ptt-24.5 inr(pt)-1.2* 02:45am fibrinoge-194 imaging: ct abd (osh): large liver laceration in the right liver lobe, with entrance stab wound. small amount of perihepatic free fluid. ct abd impression: right hepatic laceration with surrounding parenchymal hematoma is redemonstrated. there is newly apparent small focus of high density, which is as dense as the contrast within the aorta. however, etiology of this hyperdense focus is not determinant due to lack of pre-contrast imaging and delayed imaging. pseudoaneurysm is a possibility; however, pooling of contrast which was administered one day prior is also possible. active extravasation is felt to be less likely due to unchanged size of intraparenchymal hematoma and no interval development of free fluid in the abdomen since one day prior. due to superficial location of this lesion in the inferior right hepatic lobe, it is possible that evaluation for pseudoaneurysm may be possible son. brief hospital course: he was admitted to the trauma service and transferred from ed to trauma icu for close monitoring. serial exams and hematocrits were followed closely. his hematocrits were noted to remain stable. repeat imaging of his abdomen was done which showed a possible pseudoaneurysm. he subsequently underwent an angiogram and embolization of three branches of the hepatic artery. there were no procedural complications and post procedure he continued to progress. his pain was controlled adequately with oral narcotics; his diet was advanced and he was ambulating independently. he was seen by social work to assess for safety given nature of his trauma. once determined that he had a safe discharge plan he was discharged to home on hospital day 5 with follow up instructions. medications on admission: denies discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day) as needed for constipation. 2. hydroxyzine hcl 25 mg tablet sig: one (1) tablet po q4h (every 4 hours) as needed for pruritis. disp:*30 tablet(s)* refills:*0* 3. hydrocodone-acetaminophen 5-500 mg tablet sig: 1-2 tablets po q6h (every 6 hours) as needed for pain. disp:*40 tablet(s)* refills:*0* 4. magnesium hydroxide 400 mg/5 ml suspension sig: thirty (30) ml po q6h (every 6 hours) as needed for constipation. 5. zolpidem 5 mg tablet sig: one (1) tablet po hs (at bedtime). disp:*14 tablet(s)* refills:*0* discharge disposition: home discharge diagnosis: s/p stab wound assault liver laceration discharge condition: hemodynamically stable, tolerating a regular diet, pain adequately controlled. discharge instructions: return to the emergency room if you develop any fevers, chills, dizziness, shortness of breath, chest pain, abdominal pain, nausea, vomiting, diarrhea and/or other symptoms that are concerning to you. followup instructions: follow up next week with dr. , trauma surgery. call for an appointment. md, procedure: arteriography of other intra-abdominal arteries other endovascular procedures on other vessels diagnoses: assault by cutting and piercing instrument injury to liver without mention of open wound into cavity laceration, unspecified injury to hepatic artery 

Answer: The patient is high likely exposed to
