coronavirus appears to have emerged in Nigeria, Africa’s top public health official said Thursday, but he added that further investigation was needed.The discovery could add to new alarm in the pandemic after similar variants were announced in Britain and South Africa, leading to the swift return of international travel restrictions and other measures just as the world enters a major holiday season.
Another mutated coronavirus strain has been found in the U.K. “It’s a separate lineage from the U.K. and South Africa,” the head of the Africa Centers for Disease Control and Prevention, John Nkengasong, told reporters.
