President Muhammadu Buhari was in the office on Wednesday after testing negative for the coronavirus, TheCable can report.
However, he worked from home on Thursday as the office was closed for fumigation.
The president worked till Wednesday afternoon before retiring to his residence.
He had been absent on Tuesday after Abba Kyari, Buhari’s chief of staff, tested positive for the virus.
As a precaution, he was not allowed to receive any visitor with the presidential villa already looking like a ghost town following the scaling down of activities.
The intensive fumigation of the presidency began from the president’s office on Thursday morning.
The fumigators arrived at 9.30am and are expected to cover the entire presidential villa.
They fumigated the building housing the president’s office as well as the floors, corridors and major pathways.
They were dressed in white overalls and masked, in addition to wearing other protective gears.
It is believed that the coronavirus can survive on surfaces for days.
Kyari is currently in isolation and TheCable understands that he has not shown any serious symptoms, apart from occasional cough.
