Africa to be declared free of wild polio after decades of work

Achievement comes following Nigeria vaccination drive, with last cases of wild virus recorded four years ago

Africa is expected to be declared free from wild polio, after decades of work by a coalition of international health bodies, national and local governments, community volunteers and survivors.

Four years after the last recorded cases of wild polio in northern Nigeria, the Africa Regional Certification Commission (ARCC) is expected to certify that the continent is free of the virus, which can cause irreversible paralysis and in some cases death.
