Polio (poliomyelitis) is a viral illness that damages nerves that
control muscles, resulting in muscle weakness. In severe illnesses, a person
can lose the ability to move both arms and legs (paralysis) and may be unable
to breathe without help.
Symptoms of polio include:
Neck and back
Muscle weakness and pain.
Polio is now rare in developed countries, because most children
receive immunization against the virus.
