Prince Charles, the heir to the British throne, has tested positive for the coronavirus, a spokesperson said Wednesday.

The Prince of Wales is displaying mild symptoms “but otherwise remains in good health” and “has been working from home throughout the last few days as usual,” a Clarence House spokesperson said.

Camilla, the Duchess of Cornwall, was tested but does not have the virus, the spokesperson said.

The couple is now self-isolating at home in Scotland.

“The tests were carried out by the NHS in Aberdeenshire where they met the criteria required for testing,” said the spokesperson. “It is not possible to ascertain from whom the Prince caught the virus owing to the high number of engagements he carried out in his public role during recent weeks.”
