Boss Mustapha, secretary to the government of the federation (SGF), is in self-isolation as some members of his household have been confirmed positive for the coronavirus.
The SGF announced the development in a statement issued on Sunday.
According to the statement, Mustapha and his wife tested negative for the virus.
The SGF, who is also the chairman of the presidential task force (PTF) on COVID-19, added that the persons who tested positive are asymptomatic, but have been moved to a treatment centre.
“I would like to inform the general public that some members of my household tested positive for COVID-19 yesterday evening,” he said.
“Although they are currently asymptomatic, they have been isolated and are receiving care in one of the government treatment centres.
“My wife and I tested negative, but will remain in self-isolation and work from home according to protocols by the health authorities.
“I would like to remind all Nigerians that COVID-19 is real. As the Nigeria Centre for Disease Control (NCDC) announced last week, we are recording an increase in cases across several states.
“Please stay safe and protect yourself. Adhere to all public health and safety measures so that we do not lose the gains we have made in the fight against COVID-19.
“As a family, we covet your prayers. Please take responsibility for yourself and to protect our country!”
The development comes amid concerns of a second wave of infections, as the number of new cases has recorded a recent increase.
As of December 13, Nigeria had confirmed over 70,000 COVID-19 infections, but more than 65,000 patients have recovered.
