What are the symptoms of polio?

Polio, in its most debilitating forms, displays symptoms such as paralysis and death. However, most people with polio don't actually display any symptoms or become noticeably sick. When symptoms do appear, there are differences depending on the type of polio. 

Nonparalytic polio (abortive poliomyelitis) leads to flu-like symptoms that last for a few days or weeks, such as fever, sore throat, headache, vomiting, fatigue, back and neck pain, arm and leg stiffness, muscle tenderness, muscle spasms, and meningitis. 

Paralytic polio will often begin with symptoms similar to nonparalytic polio, but will progress to more serious symptoms such as a loss of muscle reflexes, severe muscle pain and spasms, and loose or floppy limbs that is often worse on one side of the body.
