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: 10:45 am ct head w/ & w/o contrast; ct 100cc non ionic contrast clip # reason: phm pw meningitis, ? brain hemorrhage, meningeal inflammation signs of encephalitis admitting diagnosis: meningitis contrast: optiray amt: 100 ______________________________________________________________________________ medical condition: 22 year old man without significant pmh p/w meningitis, has had sxs for 2 weeks without improvement. reason for this examination: please evaluate for meningeal inflammation, signs of encephalitis, and/or hemorrhage/mass effect no contraindications for iv contrast ______________________________________________________________________________ final report indication: 22-year-old man without significant past medical history, presents with meningitis. evaluate for meningeal inflammation, signs of encephalitis and/or hemorrhage/mass effect. comparison: none. technique: following routine noncontrast technique for head ct, 100 cc of intravenous optiray was administered, and repeat examination was performed. ct head, without and with intravenous contrast: there is no intra- or extra- axial hemorrhage, mass effect, or shift of normally midline structures. there is no major vascular territorial infarction. the density values of the brain parenchyma are within normal limits. the -white matter differentiation is preserved. post-contrast imaging demonstrates no evidence of enhancing lesions or masses. there is no evidence of meningeal enhancement. the surrounding soft tissue and osseous structures are unremarkable. impression: 1. no evidence of acute intra- or extra-axial hemorrhage, mass effect. 2. no evidence of enhancing lesions, or meningeal enhancement. procedure: spinal tap incision of lung diagnoses: abdominal pain, unspecified site hyposmolality and/or hyponatremia sixth or abducens nerve palsy retention of urine, unspecified iron deficiency anemia, unspecified other myelopathy tuberculous meningitis, unspecified 

Answer: The patient is high likely exposed to
