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: sulfa (sulfonamides) attending: chief complaint: altered mental status major surgical or invasive procedure: none history of present illness: this is a 33 yo f, 2 months post-partum from nsvd, who presented to an osh ( hosp ) yesterday complaining of dizziness, nausea, vomiting, tingling fingers and confusion. she was brought to the osh by her husband. as per the husband she had told him that she felt "strange, and had never felt like this before". at the ed there she had no c/o ha, recent fever, trauma. her only recent complaint was feeling constantly dehydrated despite drinking large amounts of water (+l per day), tiredness, "feeling overwhelmed" and occasional constipation. pregnancy was complicated by multiple visits to ob/l&d for "false labor" and dehydration. after arrival at the ed and placement in an exam room, she was found on the floor unresponsive, having vomited and "twitching". during her stay in the ed she was occasionally alert & awake, but agitated and combative. pertinent findings on physical exam were: afebrile, with supple neck, no signs of trauma, agitation as above, nonfocal neuro exam, downgoing babinskis. initial sodium was 120, k=3.4, bicarb 20, bun=9, cr=0.8, hct=35, wbc 10.6, fs=103. initial head ct was read as suboptimal exam motion artifact, suggestion of diffuse decrease in ventricular size & cortical sulci, grey-white differentiation, no focal parenchymal findings, ? cerebral edema. in the ed she received 3mg ativan iv, compazine 10mg iv, 1l ns. she was transferred to the icu where she was started on hypertonic saline (total of 284ml of 3% saline). she was evaluated by renal and neurology. neuro interventions included lp w/ normal opening pressure (170mm), neg csf(prot 29, glucose 70, wbc 1). other relevant findings/interventions were blood cx (ngtd), mg repletion (3g total), dexamethasone 10mg. (see below for full summary of labs etc). prior to transfer she had a mri brain that was read as (resident read) 1. diffuse sulcal inc. flair signal ? artifact vs diffuse sah vs meningitis. 2. inc cortical signal - but no ev for acute infarct/global ischemia 3. no shift - films did not accompany the patient. past medical history: 1. psychiatric admission age 13 2. interstitial cystitis, 3. pelvic pain, 4. endometriosis, 5. h/o utis psxhx: left bunionectomy social history: married, lives with husband & son, employed as psych rn family history: father w/ epilepsy, maternal gm w/ schizophrenia physical exam: pe: vs: gen: awake, does not respond to commands, agitated - saying "please help me" heent: perrla, pupils 4->3 w/ light, eomi grossly intact, neck supple, from lungs: cta b, no wheezes, ronchi, rales card: rrr, 2/6 sem best @ base, no radiation abd: soft, nd, nt, nabs ext: warm, no c/c/e neuro: alert, not responsive to commands, cn 2-12 grossly intact, maew, b le reflexes +, no clonus. did not assess gait. pertinent results: 06:24pm glucose-109* urea n-6 creat-0.6 sodium-131* potassium-3.6 chloride-97 total co2-25 anion gap-13 06:25pm urine bnzodzpn-neg barbitrt-neg opiates-pos cocaine-neg amphetmn-neg mthdone-neg 06:24pm wbc-12.8* rbc-3.89* hgb-12.3 hct-34.1* mcv-88 mch-31.7 mchc-36.2* rdw-12.5 brief hospital course: 1. altered mental status - the initial differential included new onset seizure disorder, hyponatremia (alone, or by possibly lowering seizure threshold), central demyelinating process secondary to rapid correction of hyponatremia, toxic metabolic syndromes, or other exogenous toxic ingestion, brain structural lesions (poss. causing seizures), endocrine disorders. the normal lp at osh helps eliminate meningitis. her ct at the outside hospital had shown question of cerebral edema, the mri showed diffuse increase in sucal flair signal. she was transfered from icu to the micu at . her tox screen was negative except for positive opiods. she regained mental status and was transferred to the floor. on the floor and mrv was obtained to rule out venous thrombosis causing increased icp leading to her nausea, vomiting, and altered mental status. the mrv was normal. neurology was involved in her evaluation and felt she was safe to discharge home with instructions on restricting free water intake. 2. hyponatremia - her hyponatremia seemed to be somewhat chronic in nature, although this may represent acute exacerbation. she states that she had been told to drink a lot of fluid because she was breast feeding. prior to coming into the hospital she was drinking 6-7 liters of water a day. she was placed on a free water restriction while in the hospital and her na was checked every 6, then every 12 hours. once her free water was restricted her na remained normal for the duration of her hospital admission. she met with a nutritionist while in the hospital to get advice on maintaining apropriate po intake and avoiding another occurance of this in the future. 3. psych - she was evaluated by psychology while she was in the hospital. she is to follow up with her psychologist and counselor as an outpatient. 4. prophylaxis - she was maintained on normal diet for the course of her hospital stay. she was initially treated with heparin sc but these were stopped once she was ambulating on her own. 5. breast feeding - she was initially interested in continuing to breast feed. we obtained a pump for her but told her to discard all milk until the ativan had washed from her system. she later decided that she was not interested in breast feeding as she was nervous it had contributed to her initial hyponatremia. 6. nausea - she was having trouble with nausea during her hospital admission. she was treated with zofran and compazine while in the hospital. we tested a urine hcg which was negative. medications on admission: vitamins, no herbals, no other otcs discharge medications: 1. reglan 10 mg tablet sig: one (1) tablet po every six (6) hours as needed for nausea. disp:*40 tablet(s)* refills:*1* discharge disposition: home discharge diagnosis: 1. hyponatremia discharge condition: good discharge instructions: return to emergency room if you feel any symptoms similar to those that preceeded your current admission (severe lightheadedness, nausea, finger tingling) limit free water intake to 1500 ml per day. followup instructions: please call pcp . at in 1 week follow up with dr. (psychiatrist) and (therapist) next week. procedure: spinal tap incision of lung diagnoses: hyposmolality and/or hyponatremia other convulsions 

Answer: The patient is high likely exposed to
