Charles and Camilla are currently self-disengaging at Balmoral.
Buckingham Palace said the Queen last observed her child, the beneficiary to the position of authority, on 12 March, yet was “healthy”.
The royal residence included that the Duke of Edinburgh was absent at that gathering and that the Queen was currently “following all the suitable exhortation with respect to her government assistance”.
Prince Charles, 71, is displaying mild symptoms “but otherwise remains in good health”, a spokesman said, adding that the Duchess of Cornwall, 72, has been tested but does not have the virus.
The duke and duchess showed up in Scotland on Sunday. Charles had been showing mellow side effects throughout the end of the week and was tried by the NHS in Aberdeenshire on Monday.
The outcomes came through on Tuesday night, demonstrating he was sure.
Charles is as yet working, is physically active and in great spirits.
The 71-year-old beneficiary to the honoured position last observed the Queen quickly on the 12 March. Three days sooner, mother and child had increasingly extended contact during the Commonwealth Day Service.
It is imperative to re-stress the Queen is healthy. She moved to Windsor a week ago, with the Duke of Edinburgh who originated from his typical habitation at Sandringham in Norfolk.
Given their ages, 93 and 98 separately, there will be specific consideration taken that they are not risked by this infection.
A Clarence House statement read: “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.”
