The Duchess of Cambridge, Kate Middleton has decided to go into quarantine after being exposed to someone who has recently tested positive for COVID-19, Kensington Palace confirmed on July 5.
A Royal family spokesperson made a statement on the Duchess' current health saying, "Her Royal Highness is not experiencing any symptoms, but is following all relevant government guidelines and is self-isolating at home."
The Duchess was meant to appear at an event honoring the United Kingdom's National Health Service (NHS) at St. Paul’s Cathedral in London, but due to her coronavirus exposure, the Royal couple has decided that it is best if Prince William attend the event alone in her stead.
It has not been stated exactly where Middleton came into contact with the virus, nor if it was prior to her last public appearance on July 2 at Wimbledon. While there, the Duchess of Cambridge mingled with staff and other attendees, and walked through the Wimbledon Lawn Tennis Museum.
There is no guarantee that Middleton will contract COVID-19. According to guidance written by the CDC, one reason why a person may get sick despite being previously vaccinated against COVID-19 is that the vaccine may not have had enough time to build up the patient's system prior to their exposure to the virus.
The CDC also noted those that get coronavirus post vaccinations will likely experience sickness with "less severe symptoms", and are "much less likely to be hospitalized or die than people with similar risk factors who are not vaccinated."
