Wild poliovirus type 3 (WPV3) has been eradicated worldwide, according to an independent commission of experts. The news comes today—World Polio Day—and means two of the three wild poliovirus strains are now eradicated.

The last case of WPV3 was detected in northern Nigeria in 2012. In 2015, wild poliovirus type 2 was declared eradicated from the world

“The achievement of polio eradication will be a milestone for global health. Commitment from partners and countries, coupled with innovation, means of the three wild polio serotypes, only type one remains,” said Tedros Adhanom Ghebreyesus, PhD, director-general of the World Health Organization (WHO) and chair of the Global Polio Eradication Initiative (GPEI) polio oversight board, according to a WHO story. “We remain fully committed to ensuring that all necessary resources are made available to eradicate all poliovirus strains.”

According to the WHO, no WPV3 exists anywhere in the world, apart from specimens locked in secure containment.
