How does a person's body fight off polio
Polio virus can infect only human being. Like other viruses, polio virus infect the cells. After getting attached to the cell, the virus genome is inserted into the cell body. The genetic material of the host is broken into small fragments and assembled as per the genome of the polio virus. Multiple such copies are formed and then released in the body to infect the new cells.
Computer virus' attack switches whereas human virus' affect cells.

Polio affects the nervous system.
nervous
Because the body has already experienced the virus, the body knows how to get over the virus.
Polio affects both the skeletal and muscular system. When the polio virus enters the body it immediately attacks the nervous system, followed by the muscular system. The muscular system is what gives the skeletal system the ability to move. Thus, when the muscular system gets infected the skeletal system no longer has the power to move the body to where it wants to go. This is known as paralysis.
Immunizations were formed in an attempt to fight different disease such as polio. In many parts of the world where immunizations are given, polio and other previously deadly diseases are virtually non existent.
An example of active immunity is the oral polio vaccine because it's a live attenuated vaccine. It means that, weakened polio virus will be given to you so that your body can form antibodies from it and can fight the virus. If your body itself made the antibody from an antigen, it's an example of an active immunity.
White blood cells attack it.
The entire body is effected.
