Here’s the statement from Clarence House:
“The Prince of Wales has tested positive for coronavirus. He has been displaying mild symptoms but otherwise remains in good health and has been working from home throughout the last few days as usual.
“The Duchess of Cornwall has also been tested but does not have the virus. In accordance with government and medical advice, the Prince and the Duchess are 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.
“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.”
Buckingham Palace said the Queen remains in “good health.”
Prince Charles, 71, is the eldest child of the Queen and her husband Prince Philip, the Duke of Edinburgh.
As someone over 70, he is considered to be at higher risk than average for coronavirus.
Earlier this month, his office said he was not yet self-isolating because UK government and medical advice at the time were not advising over-70s to do so.
