TheCable had reported about the anxiety at the presidential villa in Abuja over the self-isolation of Bala Mohammed, governor of Bauchi.

The governor went into self-isolation after shaking hands with Mohammed Atiku, one of the sons of Nigeria’s former vice-president, who tested positive for the virus.
