It was earlier this week that the president showed mild symptoms such as fever and cough.
On Monday he told himself that he had X-rayed his lungs and that he was feeling well.
At the time, Bolsonaro wore mouthguards, something he previously refused to wear in public. He has previously called the corona pandemic a "small flu", despite the fact that nearly 65,000 people in Brazil have died from the virus.
On Monday, however, he extended his veto against rules that force people to wear mouth protectors in public environments.
All the President's meetings and commitments have been suspended for the time being.
