In her first public statement since the news of her illness broke, the Queen sent a thoughtful and heartfelt message of congratulations.

Her eldest son Prince Charles became ill for the second time earlier this month, and his wife, the Duchess of Cornwall tested positive on Valentine's Day and self-isolated as a result.
The Queen was monitored for symptoms after meeting with the Prince and was able to continue in-person duties afterward, including a meeting with incoming Defence Services Secretary Major General Eldon Millar and his predecessor Rear Admiral James Macleod on Wednesday.

The Queen is understood to be triple vaccinated but she had been on doctors' orders to rest since mid-October, after cancelling a run of engagements and spending a night in hospital undergoing preliminary tests.
During her meeting on Wednesday, she also appeared to comment on a small issue with her mobility, as a video circulated on social media saw her pointing to her left leg or foot, and commenting: "Well, as you can see, I can’t move."
