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:
- Headache.
- Sudden fever.
- Sore throat.
- Neck and back stiffness.
- Muscle weakness and pain.
Polio is now rare in developed countries, because most children receive immunization against the virus.
