Nigerian President Muhammadu Buhari's office has dismissed a media report that indicated one of his aides had tested positive for Covid-19.

The presidency said all aides are routinely tested for coronavirus and the named staff member had always returned a negative test.

"The general public is hereby advised to ignore such stories that are intended to mislead the people an create unnecessary anxiety about the safety of the president," a statement by the president's spokesperson said.

President Buhari's former chief of staff Abba Kyari died of Covid-19 in April.
