Causes of polio

Polio is a highly contagious virus

The virus spreads by personal contact attacks the nervous system, and within a few hours can cause a person to become paralyzed, which cannot be cured. The poliovirus enters the body through the mouth and multiplies in the intestine, from where it attacks the nervous system and may cause paralysis.


Paralysis syndrome

This serious type of disease rarely occurs. Initial signs and symptoms of paralytic polio. Like fever and headache, signs and symptoms often resemble non-paralytic polio. However, within a week, other signs and symptoms appear, including:

Loss of autonomic reflexes

Severe muscle pain or weakness

Loose and weak limbs (flaccid paralysis)


Post-polio syndrome

The post-polio syndrome refers to a group of signs and symptoms that affect some people years after they have had polio. Common signs and symptoms include:

Weakness and exacerbation of muscle and joint pain


Muscular atrophy (organ atrophy)
