While Prince William got out and about in celebration of a very special event on Monday, Duchess Catherine remained at home.
The royal was exposed to the COVID-19 virus last week, with a spokesperson explaining: "Last week the Duchess of Cambridge came into contact with someone who has subsequently tested positive for COVID-19."
"Her Royal Highness is not experiencing any symptoms, but is following all relevant government guidelines and is self-isolating at home."
Naturally, fans reacted with shock and concern, but it seems that Kate will likely be fine [given she is fully vaccinated, as per HELLO!.
That said, it was absolutely right to take the measure she did to remain quarantined at home to avoid any chance of spreading the virus to others.
The event Kate was scheduled to attend on Monday was in celebration of the very people who have been at the forefront of the battle against COVID-19.
The NHS celebrated its 73rd anniversary on Monday, and to mark the day, the Duke and Duchess of Cambridge were set to host key staffers from the Health Service for a cup of tea at Buckingham Palace.
Instead, Prince William did all the hosting alone. The Prince wandered about the Tea Party speaking to guests staff ranging from nurses, care workers, counsellors to catering managers and housekeeping coordinators.
He passed on his thanks on behalf of the royals and the UK as he listened to their experiences from the past year and half.
To add, The Queen also shared her gratitude for the NHS by awarding the National Health Service with the George Cross.
"It is with great pleasure, on behalf of a grateful nation, that I award the George Cross to the National Health Services of the United Kingdom," she said in a statement.
"This award recognises all NHS staff, past and present, across all disciplines and all four nations.
"Over more than seven decades, and especially in recent times, you have supported the people of our country with courage, compassion and dedication, demonstrating the highest standards of public service."
She finished: "You have our enduring thanks and heartfelt appreciation."
