Nigeria moved closer to being declared free of wild polio, following the completion of documentation for the free status, the World Health Organisation (WHO) said.
"Today, Nigeria's complete documentation for Wild Polio virus free status was accepted by the Africa Regional Certification Commission for polio eradication (ARCC).
"It is a historic day for Nigeria, Africa and the Global Polio Programme," WHO said.
"Amazing moment in history to have had our polio-eradication documentation accepted by (ARCC); the Nigeria team led by NPHCDA and partners demonstrated evidence of our polio-free status.
