Key result
Global polio eradication efforts reduce wild poliovirus cases by >99%, though complete eradication remains elusive.
Why the study?
Despite remarkable progress in reducing wild poliovirus cases by over 99% since 1988, the goal of eradicating polio by 2000 remains unachieved with ongoing challenges.
Marked progress toward polio eradication affirms vaccination impact; leaves open final steps in remaining endemic areas.
World Polio Day 2023, on Oct 24, offered the Global Polio Eradication Initiative (GPEI) and other supporters of the cause an opportunity to reinvigorate their global call to “Make Polio History”. Since GPEI's launch in 1988, when poliomyelitis (polio) paralysed over 350 000 children every year, remarkable progress has been made in the fight against the disease: wild poliovirus cases have decreased by more than 99% and wild poliovirus types 2 and 3 have been declared eradicated. However, GPEI's original aim to end polio by the year 2000 was not met, and almost a quarter of a century on, this aim still appears elusive with two substantial challenges needing to be addressed.
