Post-polio syndrome is a condition that can affect individuals years or even decades after their initial recovery from polio. It is not caused by a reactivation of the virus and is not contagious.123

The symptoms associated with this syndrome include:

  • Muscle weakness: This may manifest as the onset of new weakness in limbs that were previously affected by the disease or in limbs that were not.12
  • Pain: Patients often experience joint and muscle pain.13
  • Fatigue: A general sense of exhaustion is a common characteristic.13
  • Muscle atrophy: Some individuals may experience a wasting or loss of muscle mass in previously affected or different muscle groups.2

The condition is believed to arise from the long-term strain placed on nerve cells that survived the original infection, which may begin to deteriorate as a person reaches middle age. While there is no cure for post-polio syndrome, it can significantly impact an individual's mobility and quality of life.23
