The chairperson of the African Union (AU) Commission Moussa Faki Mahamat on Friday disclosed that he is under quarantine, together with another AU staff member, after a colleague tested positive for coronavirus.

"I can confirm that one of my collaborators in my Office at the African Union (AU) Commission has tested positive for COVID19," the chairperson of the 55-member pan-African bloc's executive arm disclosed in a Twitter post on Friday.

"The staff member is in a stable condition. As a precautionary measure, I am under quarantine as are some other collaborators in my office," Mahamat added.

The staff member of the AU Commission, who is said to be a 72-year-old male Mauritian, is one of four new confirmed COVID-19 cases announced by the Ethiopian Ministry of Health on Friday.
