poliomyelitic in Culture
poliomyelitis (polio) [(poh-lee-oh-meye-uh-leye-tis)]

An acute disease, and an infectious disease, caused by a virus, that brings about inflammation of certain nerve cells in the spinal cord. It can have a wide range of effects, from mild to severe, including paralysis, permanent disability, and death. In the United States, the disease has now largely vanished since the development of a vaccine against it. (See Sabin vaccine and Salk vaccine.)

Note: The history of polio, which went from a major public health problem to a minor one in a short time, is often used as an example of the benefits of medical research.
Note: President Franklin D. Roosevelt suffered from poliomyelitis. During his presidency, he could not walk unaided.
