== Clinical Summary ==
Six days before his death, this 31-year-old white male became acutely ill with fever followed by an ascending paralysis which began in his feet. Three days later he was hospitalized because of difficulty in breathing. A lumbar puncture was performed and the patient's spinal fluid contained increased protein and polymorphonuclear leukocytes (4.30 PMNs/cmmmm³). He died on the third hospital day.

== Study Questions ==
* <spoiler text="How does poliovirus cause cell death?">Poliovirus replicates inside neurons and causes lysis of the cell.</spoiler>
* <spoiler text="What is the mode of transmission of poliovirus?">Poliovirus is an enterovirus that is usually acquired from contaminated water. It has been effectively controlled by immunization; however, among the nonimmune it causes a nonspecific gastroenteritis. In a small fraction of the vulnerable population, it can invade the nervous system where it attacks lower motor neurons.</spoiler>
