Magaji took to his Facebook to express joy over the passage of Kyari, who died of coronavirus, declaring ‘Nigeria is free’.
He was sacked by Governor Abdullahi Ganduje, on April for “making improper comments” on Kyari’s death.
But Magaji denied he celebrated Kyari’s death, saying “people only misunderstood me.”
In a Facebook post on Thursday, he revealed he had tested positive for coronavirus.
He said: “Dear all, I do truly apologize to you not getting across to me on phone or messages.
“I have been indisposed due to ongoing health challenges some of us going through in Kano. In Sha Allah, it will be well.
“This morning my NCDC test is out. I have been confirmed COVID-19 positive and have been moved to one of the state facilities… pray for us.”
