- an acute viral disease, usually affecting children and young adults, caused by any of three polioviruses, characterized by inflammation of the motor neurons of the brain stem and spinal cord, and resulting in a motor paralysis, followed by muscular atrophy and often permanent deformities.

- an acute infectious viral disease, esp affecting children. In its paralytic form (acute anterior poliomyelitis) the brain and spinal cord are involved, causing weakness, paralysis, and wasting of muscleOften shortened to: polio Also called: infantile paralysis
Word Origin and History for poliomyelitis
1874, also polio-myelitis, coined by German physician Adolph Kussmaul (1822-1902) from Greek polios "grey" (see fallow (adj.)) + myelos "marrow" + -itis "inflammation." So called because the gray matter in the spinal cord is inflamed, which causes paralysis. The earlier name was infantile paralysis (1843).
In many respects, also, this affection resembles the acute spinal paralysis of infancy, which, from the researches of Charcot, Joffroy, and others, have been shown pathologically to be an acute myelitis of the anterior cornua. Hence, for these forms of paralysis, Professor Kussmaul suggests the name of 'poliomyelitis anterior.' ["London Medical Record," Dec. 9, 1874]
- A highly infectious viral disease that chiefly affects children and, in its acute forms, causes inflammation of motor neurons of the spinal cord and brainstem, leading to paralysis, muscular atrophy, and often deformity.infantile paralysis
- A highly communicable infectious disease caused by the poliovirus of the genus Enterovirus that causes inflammation of motor neurons of the spinal cord and brainstem, leading to paralysis, muscular atrophy, and often disability and deformity. Childhood vaccinations are given to prevent infection. Also called polio
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.)
