With no recorded cases since 2016 , the World Health Organisation has declared Africa free of the wild polio virus alongside with Nigeria.
The certification comes 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.
The official announcement is due at 1500 GMT in a videoconference with WHO director-general Tedros Adhanom Ghebreyesus and key figures including philanthropist and Microsoft founder Bill Gates.
“Happiness is an understatement. We’ve been on this marathon for over 30 years,” said Tunji Funsho, a Nigerian doctor and local anti-polio coordinator for Rotary International.
He said it marked a crucial step in the total eradication of the illness at the global level.
“It’s a real achievement, I feel joy and relief at the same time,” he added.
Poliomyelitis, or “wild polio” is an acutely infectious and contagious disease which attacks the spinal cord and causes irreversible paralysis in children.
