Being diagnosed with COVID-19 is likely not the way Queen Elizabeth II expected to mark the start of her Platinum Jubilee year.
The 95-year-old is two weeks into celebrating 70 years on the throne, but is now the latest member of the Royal Family to test positive to COVID.
Buckingham Palace says, aside from mild cold-like symptoms, the Queen is feeling well and is continuing with light duties.
The Queen has been keeping a fairly low profile since the death of her husband Prince Philip last April. She has only recently returned to public duties after cancelling a two-day trip to Northern Ireland in October, before staying in hospital overnight for an unspecified ailment later that month.
It's not known exactly how the Queen contracted Covid-19. However, her health has been in the spotlight since her son Prince Charles contracted the virus earlier this month, while the BBC has reported a number of people have tested positive where the Queen resides.
Here's what we know about her recent movements.
February 5: Jubilee eve
The night before marking her 70 years as monarch, the Queen hosted an in-person reception for local community members and volunteer groups at Sandringham House.
She also released a message for the occasion, and wrote that she was approaching the year ahead with "a sense of hope and optimism".
The Queen also expressed her wish for Camilla to become known as Queen Consort when Prince Charles becomes King after her death.
February 6: 70th anniversary
The actual day marking her seventh decade as monarch was a subdued affair for the Queen.
Prince Charles released a statement to celebrate the Queen's "remarkable achievement", and Buckingham Palace released a photo of her with her famous red boxes, which deliver her daily papers from her private secretaries and include government messages and documents.
February 9: Meeting with British PM
The Queen meets with the British Prime Minister Boris Johnson once a week to discuss important national matters and political events, as has been the case with all British Prime Ministers since she became Queen in 1952.
Throughout the pandemic these meetings were held virtually, but the Queen and Mr Johnson met in person in late June last year.
It's unclear whether she met with the Prime Minister in person or virtually on this occasion.
The meetings, known as "Audiences", last for around 20 minutes and are entirely private conversations.
February 10: Prince Charles tests positive
Prince Charles' office, Clarence House confirmed that he had contracted COVID for a second time.
A palace source then confirmed that Prince Charles had recently met with the Queen, with the BBC reporting that meeting took place at Windsor Castle on Tuesday, February 8.
After the diagnosis, palace sources said the Queen was not displaying COVID symptoms, but was being monitored.
February 15: Virtual meetings with ambassadors
The Queen's next public engagements shared by the Palace were virtual meetings with the new Estonian and Spanish ambassadors.
She held virtual Audiences with Viljar Lubi from Estonia and José Pascual Marco Martínez from Spain, where both ambassadors presented Letters of Recall from their predecessors and their respective Letters of Credence.
It is customary for Ambassadors and High Commissioners in London to meet with the Queen shortly after beginning in the role.
February 16: Queen feeling 'stiff'
It was another day of Audiences for the Queen, who first met with the Bishop of Portsmouth virtually.
She also met with changing Defence Service Secretaries in person. Pictures which the Palace later shared on Instagram show the Queen clutching her walking stick — something she hasn't been seen with in years.
The Queen also had her weekly meeting with British Prime Minister Boris Johnson, this time over the phone.
Palace sources said the Queen reported feeling stiff on this day and that she was unable to move.
When asked how she was, the Queen responded: "Well, as you can see, I can't move," before gesturing at her feet.
A palace source later said that she had been feeling 'slightly stiff' rather than having injured herself or being unwell.
That prompted fresh concerns for her health.
February 17: A third day of meetings
Despite feeling stiff the day before, the Queen had a third-straight day of Audiences, this time with more ambassadors.
On this day she virtually met with Jukka Siukosaari from Finland and Manaar Dabbas from Jordan.
The Palace also shared separate snippets of these meetings.
February 20: 'Mild' COVID diagnosis
On Sunday, Buckingham Palace confirmed the Queen had contracted COVID and was experiencing mild, cold-like symptoms.
The palace said the monarch would continue light duties at Windsor over the next week, and is triple-vaccinated against COVID-19.
"She will continue to receive medical attention and will follow all appropriate guidelines," the palace said.
Current guidelines require people who test positive for COVID-19 to self-isolate for at least five days. However, that requirement is expected to be lifted by the British government in the coming week.
Juliet Rieden, the ABC's royals correspondent said she expected the Queen to isolate at Windsor Castle, and would "presumably have her meals delivered outside her door".
"I don't see any reason why she would end up in hospital or anything like that," Rieden said.
"I think she's probably in the top 5 per cent health-wise, and certainly she can call on the best healthcare Britain can provide."
