Our Progress Against Polio

Polio Map 1988-2018

CDC and its international partners have made significant progress over the past 26 years.

  • The number of worldwide polio cases has fallen from an estimated 350,000 in 1988 to 407 in 2013—a decline of more than 99% in reported cases.
  • Four regions of the world are certified polio free—the Americas, Europe, South East Asia and the Western Pacific. Only three polio-endemic countries (countries that have never interrupted the transmission of wild poliovirus) remain—Afghanistan, Nigeria, and Pakistan.
  • Without our polio eradication efforts, more than 17 million people who are currently healthy would have been paralyzed by the virus.
  • For the latest polio reports, visit the Global Polio Eradication Initiative (GPEI).External
