Nigeria, Africa’s most populous country, on Wednesday confirmed its first cases of the new Covid-19 variant, saying it had been found among three passengers who had travelled to South Africa.
West African neighbour Ghana also said it had recorded the new Omicron variant, tracing cases to Nigeria and South Africa.
Cases of Omicron have been detected in numerous countries since the strain was first reported to the World Health Organization (WHO) in South Africa last week, prompting border closures and travel restrictions.
Nigeria’s announcement came as South African President Cyril Ramaphosa visited Abuja during a West African tour where he called for solidarity against “counter-productive” travel bans.
“Genomic surveillance has now identified and confirmed Nigeria’s first cases of the B.1.1.529 SARS-CoV-2 lineage, now known as the Omicron variant,” said the head of Nigeria’s Centre for Disease Control, Ifedayo Adetifa.
Contact tracing and “follow up to ensure isolation… have commenced,” Adetifa said.
“Omicron is widespread globally… Therefore, it is a matter of when not if, we will identify more cases,” he said.
Ghana’s director-general of health services, Patrick Kuma-Aboagye, said its cases had been detected at Accra’s international airport, mainly coming from South Africa and Nigeria
