“Polio, or poliomyelitis, is an infectious viral disease that can harm the nervous system. Post-polio syndrome (PPS) usually occurs 15-40 years after the infection and recovery. PPS is believed to be the result of a deterioration of nerve cells called motor neurons over many years that leads to loss of muscle strength and dysfunction from Polio virus.

Polio and post-polio syndrome are caused by poliovirus. Unlike polio, PPS is not contagious but more a extended result from it for some who get PPS. Only a polio survivor can develop PPS yet not everyone who survives polio will develop PPS.

The polio vaccine is the answer and has essentially eradicated a lot of polio from the U.S. However, polio still exists in some countries and cases of PPS still arise.”
