The Chief of Staff to the President, Abba Kyari, has reportedly tested positive for COVID-19.

A top source at the Federal Ministry of Health disclosed on Tuesday that Kyari, who recently returned from Germany, had tested positive.

The source, however, said the President, Major General Muhammadu Buhari (retd.), had tested negative but the President would be tested again in a few days.

At 65, Kyari is one of the oldest persons in Nigeria with a confirmed case of the novel coronavirus.
