Queen Elizabeth II has been infected with the coronavirus, Buckingham Palace said Sunday, becoming one of the world’s most prominent figures to battle the virus and deeply rattling the country she has led for seven decades.

The palace issued few details about the condition of the queen, who turns 96 in April. She is one of several people at Windsor Castle who are infected, a palace official said, suggesting an outbreak at the royal residence, west of London, where the queen has spent most of her time since the pandemic engulfed Britain in March 2020.

"Buckingham Palace confirm that the queen has today tested positive for COVID,” the palace said in a statement. "Her Majesty is experiencing mild coldlike symptoms but expects to continue light duties at Windsor over the coming week. She will continue to receive medical attention and will follow all the appropriate guidelines.”
