Queen Elizabeth feeling 'a lot better' after COVID-19 diagnosis and returns to work

Queen Elizabeth has returned to work after battling COVID-19, with Prince Charles saying his mother is feeling "a lot better".

The monarch carried out two virtual engagements from Windsor Castle with ambassadors, the first time she had been seen since being diagnosed with coronavirus.

The Queen was confirmed to have COVID-19 on Sunday February 20 with Buckingham Palace announcing Her Majesty was "experiencing mild cold-like symptoms".

She was forced to cancel a number of similar engagements due to the lingering effects from the virus.

But the 95-year-old must have felt well enough to speak to foreign diplomats on Tuesday, meeting the new ambassadors of Andorra and Chad.

During the two audiences, Her Majesty wore a green dress with a large brooch and her pearls.

It comes as Prince Charles was asked about his mother's health during a visit to Southend-on-Sea.

Member of the public Janice Jacom said of their conversation: "I asked the prince about his mother and he said 'she's a lot better now - it was very mild'.

"It was a bit worrying as the Queen is getting on a bit but I think she's absolutely wonderful."

The Prince of Wales and the Duchess of Cornwall were attending their first joint engagement since contracting COVID-19, Prince Charles' second infection and Camilla's first.

On Sunday the Queen is reported to have left Windsor Castle visit the grounds of Frogmore House, where she enjoyed time with some of her grandchildren and great-grandchildren.

They included the Duke and Duchess of Cambridge and their three children Prince George, Princess Charlotte and Prince Louis.

Princess Beatrice and her daughter, Sienna, were also present.

The Queen was due to host an in-person Diplomatic Reception at Windsor Castle today, March 2, but the event was scrapped on advice from the British Foreign Secretary due to the situation in Ukraine, rather than because of the Queen's health.

The Queen is expected to continue with her constitutional duties at the castle and carry out a number of private events.

She has a number of high-profile engagements that she is due to attend, including the Commonwealth Service at Westminster Abbey on March 14, and the Duke of Edinburgh's memorial service, also at the Abbey, on March 29.
