Africa has been 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) on Tuesday certified that the continent is now free of the virus, which can cause irreversible paralysis and in some cases death.
The achievement is the result of a campaign to vaccinate and monitor children in Borno State, the final front of polio eradication efforts on the continent, and the heart of the jihadist insurgency in Nigeria.
