PARTICIPATION GUIDELINES WHAT IS POLIO? Polio is a highly infectious disease that most commonly affects children under the age of 5. No cure is available, but polio is preventable with a vaccine. Only two countries remain endemic—Pakistan and Afghanistan. We have reduced cases by 99.9% since 1988. Until we end polio forever, every child is at risk.
