It said Stoyanov had been on leave since October 26, and his last contact with staff at the presidential administration occurred three days earlier.
The president, whose role is largely ceremonial, and employees who had been in contact with Stoyanov are to carry out their duties remotely while under quarantine.
Prime Minister Boyko Borisov and Central Bank Governor Dimitar Radev are also in quarantine after testing positive for the virus.
As of October 29, Bulgaria closed universities, high schools, and nightclubs for two weeks as the country struggles to contain a surge in coronavirus cases.
