Buckingham Palace says Queen Elizabeth II has tested positive for COVID-19 and is experiencing mild, cold-like symptoms.
The palace said Sunday that the 95-year-old British monarch would continue with "light" duties at Windsor Castle over the coming week.
"She will continue to receive medical attention and will follow all the appropriate guidelines," the palace said in a statement.

People in the UK who test positive for COVID-19 are required to self-isolate for at least five days, though the British government says it plans to lift that requirement for England in the coming week.
The Queen is believed to have received three jabs of coronavirus vaccine.
Both her eldest son Prince Charles and daughter-in-law Camilla, Duchess of Cornwall have also recently contracted COVID-19. Charles has since returned to work.
Senior British politicians sent get-well messages.
"I'm sure I speak for everyone in wishing Her Majesty The Queen a swift recovery from COVID and a rapid return to vibrant good health," Prime Minister Boris Johnson tweeted.

Britain's longest-reigning monarch, the Queen reached the milestone of 70 years on the throne on February 6.
A fixture in the life of the nation, she has been in robust health for most of her reign and has been photographed riding a horse as recently as 2020.
In the past year she has been seen using a walking stick, and in October she spent a night in a London hospital for unspecified tests.
The Queen's doctors ordered her to rest after that and she was forced to cancel appearances at several key events, including Remembrance Sunday services and the COP26 climate conference in Glasgow, Scotland in November.
This month she returned to public duties and has held audiences both virtually and in person with diplomats, politicians and senior military officers.
During one exchange caught on camera last week, she walked slowly with a stick and said "as you can see I can't move" in apparent reference to her leg.

Joe Little, managing editor of Majesty magazine, said members of the royal family would be concerned by the COVID-19 diagnosis, given the Queen's age. She turns 96 on April 21.
"In the coming days a very close eye will be kept on her and the indications are that, all being well, it's nothing more than a minor inconvenience," he said.
The Queen is also scheduled to attend a string of in-person public engagements in the coming weeks, including audiences with politicians and diplomats, a diplomatic reception at Windsor on March 2 and the Commonwealth Service at Westminster Abbey on March 14.
Public celebrations of the Platinum Jubilee are scheduled for June, with festivities including a military parade, a day of horse-racing and neighboUrhood parties over a June 2–5 long weekend.
