Schools will reopen in Nigeria's commercial hub of Lagos next month as part of plans to revive the economy as COVID-19 cases decline, the state governor said.

Lagos, the epicentre of the pandemic in Nigeria, plans to reopen colleges on September 14, and primary and secondary school schools on September 21, Babajide Sanwo-Olu said.

"The gradual easing doesn't mean the pandemic is over," he said in a tweet. "It is not an invitation to carelessness or nonchalance."

The Lagos governor said restaurants, social clubs and recreational centers would also be allowed to reopen as long as they followed safety rules.

Nigeria has reported 53,727 infections in total - including 18,104 in Lagos - and 1,011 deaths.
