After being in contact with someone who was positive for COVID, Kate Middleton is now isolated.According to reports, Kate had a conversation with a person who had the virus last week. British guidelines state that people with COVID must self-isolate after coming in contact.At least not so far, it doesn't appear to have had any impact on her health. Kensington Palace representatives said that "Her Royal Highness isn't experiencing any symptoms but is following all relevant government guidelines. She is self-isolating at her home."This is how difficult it can be. Kate arrived at Wimbledon Friday to meet with staff from the All England Club kitchens. As she walked through Wimbledon Lawn Tennis Museum, she also interacted with others.She was also present at the England Euro 2020 match at Wembley Stadium on June 29 with Princes William, George and George.Kate was vaccinated in May so she is most likely to experience flu-like symptoms if she has COVID.
