A person who contracts paralytic polio will feel tired and stiff, and experience muscle spasms. More acute pain, loss of reflexes, and sudden paralysis can follow. These symptoms may be temporary, cause permanent disability, or in the most severe cases, end in death. There is no cure for polio, and in many affected countries there are few supportive therapies for paralytic polio.
Commonly known as polio, poliomyelitis is caused by the poliovirus. The disease is commonly spread by an infected person’s feces; the insidious virus can spread both before and after symptoms appear. Although the majority of people who contract polio do not exhibit symptoms, and others only experience flu-like symptoms, they still have the ability to infect others.source Young children with low resistance to the virus, especially in places with poor sanitation, are at particularly high risk for transmission.
