What statements are true about polio?

Polio, or poliomyelitis, is a highly infectious viral disease caused by the poliovirus, primarily affecting children under five. It can lead to paralysis, and in severe cases, it can be fatal. Vaccination has been highly effective in reducing polio incidence worldwide, with the Global Polio Eradication Initiative significantly decreasing cases since its launch. However, the disease remains endemic in some regions, highlighting the importance of continued vaccination efforts.
