“Post-polio syndrome (PPS) is a non-contagious condition that can affect polio survivors usually 15 to 40 years after recovery from polio.  Only a polio survivor can develop PPS, it is not contagious.

The polio vaccine has eradicated polio from the United States.  However, polio still exists in some countries and cases of PPS still arise. ”
