Kate Middleton is in self-isolation after being near someone who tested positive for Covid-19, according to a statement from Kensington Palace. Although the Duchess of Cambridge was vaccinated in May and is reportedly asymptomatic, the United Kingdom requires everyone who comes into contact with a confirmed case to quarantine for 10 days.

The Duchess was visibly missing when her husband, Prince William, hosted the NHS Big Tea alone at Buckingham Palace in London to honor the National Health Service staff and frontline workers.

William was spotted socializing with guests and the prince, who is second in line to the British throne, even became conductor for a bit while the band played!

The NHS celebrated its 73rd anniversary with a tea party after a service at St. Paul’s Cathedral, in which the George Cross was given out. The George Cross is an award given to people who show tremendous bravery in non-combat situations. Queen Elizabeth’s father, George VI, introduced the award in 1940.

Those who were honored included NHS Chief Sir Simon Stevens, Matron May Parsons, who gave the first Covid shot outside of trials, Sam Foster, the nurse who gave the first Oxford Astra Zeneca vaccine, staff who treated early Covid-19 patients, and patients who were treated for the virus.

Kate Middleton, who was originally slated to appear alongside her husband, was not able to attend. “Last week the Duchess of Cambridge came into contact with someone who has subsequently tested positive for Covid-19,” a spokesperson for the palace said earlier on Monday. “Her Royal Highness is not experiencing any symptoms, but is following all relevant government guidelines and is self-isolating at home.”

Kate Middleton has been busy recently. She attended soccer tournaments last week with their son, 7-year-old Prince George, and had negative Covid-19 tests before each event. On Friday, she was at Wimbledon and sat in a royal box with the Duke of Kent (The Queen’s first cousin, Edward). Later she sat with British tennis star Tim Henman. Kensington Palace hasn’t shared when she may have been exposed or who the infected person is.

Prince William was diagnosed with Covid-19 in April 2020 and reportedly “struggled to breathe.” At the time, he tried to keep the news out of the press because his father Prince Charles and the country’s prime minister, Boris Johnson, were also diagnosed with the virus.

Kate Middleton previously announced that they received their first dose of the Covid-19 vaccination on May 28 at London’s Science Museum. Middleton has now received her second dose. The Duchess also takes tests twice a week during the royal household’s testing program.
