Post-polio syndrome (PPS) is a condition that affects
survivors. About 20%-40% of people who recover from polio will later develop PPS. The onset may occur 10-40 years after the initial polio attack.
The exact cause is unknown. It is not related to the original polio virus itself.
Instead, the syndrome is due to nerve and muscle damage that may have been caused by the original infection.
Factors that may increase your chance of developing PPS include:
Previous polio attack
Severe original polio attack
Later age at onset of infection
Symptoms may include:
Slowly progressive muscle weakness
Difficulty swallowing or breathing
Intolerance to heat or cold
