Clinical Information

Polio is an acute infectious disease affecting humans, especially children, caused by any of the three serotypes of the human poliovirus. The infection typically remains confined to the gastrointestinal tract and nasopharynx and is often asymptomatic. However, it can affect the central nervous system, primarily the spinal cord, resulting in rapidly progressing paralysis, muscle twitching (coarse fasciculation), and decreased reflexes (hyporeflexia). Motor neurons are mainly impacted, and encephalitis may also occur. The virus replicates in the nervous system and can cause significant neuronal loss, particularly in the spinal cord.

Typically, the infection is confined to the gastrointestinal tract and nasopharynx, and often does not produce symptoms. However, the central nervous system, particularly the spinal cord, can be affected, leading to quickly progressing paralysis, muscle twitching (coarse fasciculation), and reduced reflexes (hyporeflexia). Motor neurons are mainly impacted. In some cases, encephalitis, an inflammation of the brain, may occur. The virus replicates within the nervous system, potentially causing significant neuronal loss, especially in the spinal cord. A rare related condition, nonpoliovirus poliomyelitis, can result from infections with nonpoliovirus enteroviruses. This information is derived from “Principles of Neurology” by Adams et al., 6th edition, pages 764-5.
An acute infectious disorder that affects the nervous system. It is caused by the poliovirus. The virus spreads by direct contact, and can be prevented by prophylaxis with the polio vaccine.
