The Queen has taken up residence in Windsor Castle after leaving Buckingham Palace.
Her Majesty has moved to Windsor following crisis talks as the government decides how best to tackle the coronavirus pandemic.
It is understood that if the situation continues to worsen, she will be placed into quarantine at Sandringham alongside the Duke of Edinburgh.
Her Majesty usually stays at Windsor over the weekends. It is unclear whether she will return to Central London next week, or if she will stay in Berkshire to carry out her constitutional functions.
The death-toll in the UK from coronavirus doubled on Saturday, with 21 people now confirmed to have died from the disease.
The elderly and those with respiratory problems are the most vulnerable.
Speaking of The Queen’s situation, a source told The Sun: “She is in good health but it was thought best to move her. A lot of her staff are a bit panicky over coronavirus.
“The Queen has met a lot of people there until recently. But she is weeks away from her 94th birthday and advisers believe it is best to get her out of harm’s way.“
The monarch, who turns 94-years-old next month, has already cancelled engagements next week in Cheshire due to COVID-19.
It is expected that her other commitments will also be cancelled should the government advice be for her to do so.
Prime Minister Boris Johnson is expected to tell all over 70s, which includes The Queen, the Prince of Wales & the Duchess of Cornwall, to self isolate in their homes for a period of up-to four months.
ITV’s Political Editor Robert Peston says that the government is likely to announce the drastic measures at some point within the next couple of weeks.
Mr Peston says the “wartime-style” mobilisation will aim to protect the most vulnerable from Coronavirus.
This would see senior members of The Royal Family being forced to self-isolate, including The Queen who turns 94-years-old next month.
The elderly heir to the throne, 71-year-old Prince Charles, may also have to stay in isolation in Clarence House alongside the 72-year-old Duchess of Cornwall.
