@James231 The annual number of wild poliovirus cases has declined by more than 99.9% worldwide from an estimated 350,000 in 1988 when the Global Polio Eradication Initiative was launched.
Five out of six World Health Organization regions are now certified wild poliovirus free—the African Region, the Americas, Europe, South East Asia and the Western Pacific.
Of the three serotypes of wild poliovirus, type 2 was certified as eradicated in 2015 and type 3 was certified as eradicated in 2018. https://www.cdc.gov/polio/progress/index.htm
There were 140 reported cases of wild poliovirus (WPV) in 2020. Polio remains endemic in only two countries. https://www.kff.org/global-health-policy/fact-sheet/the-u-s-government-and-global-polio-efforts/
