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 46 year-old man with a past medical history of hyperthyroidism and hypertension being transferred to the neurology service for further evaluation. he was in his usual state of health until saturday about 3:00 p.m. when he began to feel generally uncomfortable at work. he went outside for some fresh air, but when he came back inside the uncomfortable sensation was still there. he reports not only becoming stiff and losing his sense of touch. he was falling to the left side and a co-worker needed to help him to his chair to sit down. his mouth would not open and he was able to move his body. he then passed out. he did not wake up for about six hours. after being intubated in the emergency room. he could not speak normally when he woke up. his face was noted to be drooping on the left side two days after he was initially seen. the patient does not report any limb weakness after awakening. initially he was clumsy, but he no longer feels clumsy. he has no double vision and no swallowing problems. has no headache, dizziness, neck ache, pain behind his ear or hearing loss. past medical history: hypertension and hyperthyroidism. medications on admission: 1. norvasc 10 mg po q.d. 2. propylthiouracil 50 mg po b.i.d. allergies: no known drug allergies. family history: mother had heart disease. brother had hypertension. one episode of presyncope. social history: lives at home with sister and her family. he works at a chinese restaurant. no present alcohol use. quit smoking ten years ago. physical examination: vital signs temperature 99.5. blood pressure 118/70. pulse 76. breathing at 20. o2 sat 98% on room air. in general, the patient is a well nourished, well developed middle aged man lying in bed appearing comfortable. heent no trauma. mucous membranes are moist. neck no bruits or thyromegaly. pulmonary clear to auscultation bilaterally. cvc regular rate and rhythm. no murmurs. abdomen soft and nontender. extremities 2+ pulses no edema. neurological mental status he is awake and alert. he appears fluent and appropriate, but examination is translated. cranial nerves, acuity is 20 and 20 ou, pupils are equal, round and reactive to light. extraocular movements without diplopia or nystagmus. secedes are full. facial sensation is normal. lower motor neuron type facial weakness on the left. hearing is intact to finger rub bilaterally. tongue and palette are symmetric. motor examination normal tone and bulk. full strength throughout. reflexes 2+ in upper extremities. difficult to elicit in lower extremities. toes are down going bilaterally. sensation is intact to gross touch and pin prick throughout. coordination finger nose, rapid alternating movements, heel to shin is intact. gait is normal. laboratory: white blood cell count 12.9, hematocrit 43, platelets 276, sodium 137, potassium 3.7, chloride 104, bicarb 22, bun 15, creatinine .8, glucose 110. calcium, magnesium and phosphate 9, 2 and 2.8. ck are negative. rpr is pending, which turned out to be negative. radiology showed a left large cerebellar hemisphere infarct also effecting the vermis with some edema and question of cranial nerves vii and vi, the pons. the artery does not fill with blood and the vertebrals are occluded bilaterally. hospital course: the patient was on the neurology service. he was transferred to neurology on . aggrenox was continued. his blood pressure was kept over 140. he had an angiogram of his neck, which failed to show filling of the basilar or vertebral arteries. it was determined that the best therapy for the patient was aspirin and coumadin. he was started on coumadin 5 mg po q.h.s. and aspirin 325 mg po q.d. his aggrenox was discontinued. the patient was discharged home on . discharge diagnosis: left cerebellar hemisphere infarction and left facial nerve compression by edema from that infarction. he will be discharged on aspirin and coumadin and have his inr checked frequently. his antihypertensives will be held, because it is our goal to keep his blood pressure greater then 140. he will follow up with in clinic. , m.d. dictated by: medquist36 procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours spinal tap incision of lung insertion of endotracheal tube arteriography of cerebral arteries diagnoses: unspecified essential hypertension thyrotoxicosis without mention of goiter or other cause, and without mention of thyrotoxic crisis or storm other late effects of cerebrovascular disease, facial weakness occlusion and stenosis of vertebral artery with cerebral infarction palpitations 

Answer: The patient is high likely exposed to
