The World Health Organisation (WHO) is set to certify on Tuesday that the African continent is free from wild polio, four years after the last cases appeared in northeastern Nigeria.
"Thanks to the relentless efforts by governments, donors, frontline health workers and communities, up to 1.8 million children have been saved from the crippling life-long paralysis," the WHO said in a statement.
