Post-polio syndrome (PPS or post-poliomyelitis syndrome or post-polio sequelae) is a condition that affects approximately 25–50% of people who have previously contracted poliomyelitis—a viral infection of the nervous system—after the initial infection. Typically the symptoms appear 15–30 years after recovery from the original paralytic attack at an age of 35 to 60. Symptoms include acute or increased muscular weakness pain in the muscles and fatigue.
