(redirected from paralytic poliomyelitis)
Also found in: Thesaurus, Medical, Encyclopedia.


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. Through vaccination, the disease is preventable. Also called infantile paralysis, polio.

[Greek polios, gray (since it affects the gray matter); see pel- in Indo-European roots + myelitis.]

po′li·o·my′e·lit′ic (-lĭt′ĭk) adj.


(Pathology) 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 muscle. Often shortened to: polio Also called: infantile paralysis
[C19: New Latin, from Greek polios grey + muelos marrow]


(ˌpoʊ li oʊˌmaɪ əˈlaɪ tɪs)

an acute infectious disease of motor nerves of the spinal cord and brain stem, caused by a poliovirus and sometimes resulting in muscular atrophy and skeletal deformity: formerly epidemic in children and young adults, now controlled by vaccination.
[1875–80; < Greek polió(s) gray (referring to the gray matter of the spinal cord) + myelitis]


(also known as polio) A virus infection of groups of muscles, with severe symptoms. Vaccine is available against this.
