Where Data Tells the Story

Wild poliovirus has three serotypes. The three serotypes are distinct types of poliovirus with protein structures that differ sufficiently that protection from one doesn’t protect from the other.
The world has eradicated wild poliovirus serotypes 2 and 3.
The world is, therefore, very close to eradicating all serotypes of wild poliovirus globally.
As shown in the map above, only two countries — Afghanistan and Pakistan — are still endemic for wild poliovirus serotype 1 (WPV1). In 2023, only six cases of wild polio were reported in Afghanistan and another six in Pakistan.
By testing widely to identify potential cases, working with local communities in hard-to-reach areas and at borders, and improving vaccination rates and sanitation, this goal is within reach.
