The Queen and the Royal Family are 'at-risk' of developing severe coronavirus symptoms and are speaking to medics daily to ensure their safety.
A doctor who spent seven years as The Firm's resident medic said they too are self-isolating in separate bedrooms if they show telltale symptoms like a cough or fever.
Dr Anna Hemming, from The Cranley Clinic, told Tatler : "Clearly, members of the Royal Family are in high risk groups - not just over 70 but over 90 years old too.
"I believe the family will be talking daily with their medical team and taking all reasonable precautions, particularly for the Duke of Edinburgh who we are all aware is the most fragile member of the Royal Family."
The Queen left Buckingham Palace for Windsor Castle as the coronavirus ravaged London. Since large crowds greet her at every public appearance, The Monarch has decided to self-isolate for 14-days for the sake of her husband.
Prince Philip, 98, has suffered various health conditions in recent weeks and is being sheltered by a medical-team on hand and by other members of his family.
The Duke of Edinburgh was flown by helicopter from the Sandringham estate where he has been staying in his secluded Wood Farm cottage.
Royal commentator Angela Mollard and New Idea's Zoe Burrell have told of the steps the royal highness is taking. Speaking on the Royals podcast, they said: "You have to remember her husband Prince Philip is very elderly and very vulnerable.
"I think the Queen would be very much limiting any kind of interaction.
"Certainly some of her engagements have gone by the wayside.
"In the short term, the Palace has put out that, there have been amendments to royal diaries."
She continued: "The Queen was supposed to go to Camden and to Cheshire, that's been cancelled.
"So in terms of our visibility of the royals over the next weeks and months, I think it's going to be interesting.
"As the Palace has said, the Queen will still be having her one-on-one meetings.
"There was talk that she would be in lockdown at Sandringham if things escalated. That is very, very unlikely."
The royal couple will be based at Windsor with a reduced number of staff as a precaution, and will be following the advice of their Medical Household and the Government.
Princess Beatrice has cancelled her royal wedding reception in the palace gardens in May but is still planning to wed in a small private ceremony if possible.
The Queen and Philip are not the only members of the royal family affected by the Government's advice on social distancing.
The Prince of Wales is 71 and the Duchess of Cornwall is 72.
A source added of Charles: "The Prince is operating as close to business as usual as possible at the moment."
The Prince, who was once described by Camilla as "not one for chilling", is known for his busy work schedule.
His Clarence House team are working mostly remotely, having set up a virtual, digital office.
The news follows advice from the Government's top scientific advisers who have warned young people not to be complacent over Covid-19 as they urged the public to keep up social distancing measures to protect themselves.
