The 95-year-old queen, who has been fully vaccinated against coronavirus, joked to Palace staff just four days ago that she couldn't move much. She spent a night in the hospital last October for an unspecified ailment. The Palace announced today that the Queen has tested positive for COVID-19. Despite experiencing mild cold-like symptoms, she plans to continue light duties at Windsor over the next week. The Palace stated that she will continue to receive medical attention and follow all appropriate guidelines. Earlier this month, Charles, 73, the heir to the throne, had to withdraw from an event after contracting COVID-19 for a second time. A source from the Palace mentioned that he had recently met with the queen, who is the world's oldest monarch. Elizabeth quietly celebrated the 70th anniversary of her reign as the queen of Britain and several other realms in early February. Elizabeth ascended to the throne on Feb. 6, 1952, following the death of her father, King George VI, while she was in Kenya on a tour. She is the first British monarch to reign for seven decades in a dynasty that dates back nearly 1,000 years to Norman King William I and his conquest of England in 1066. Throughout her historic reign, Elizabeth has successfully maintained the popularity of the British monarchy despite significant political, social, and cultural changes that threatened to render royalty obsolete. When she took the throne, Josef Stalin, Mao Zedong, and Harry Truman were leading the Soviet Union, China, and the United States, respectively, with Winston Churchill serving as British prime minister. Over the course of her reign, she has been served by 14 prime ministers in Britain, including Churchill. She has met all 14 U.S. presidents during her time as queen, except for Lyndon Johnson. Elizabeth's dedication to her duties has earned her support and respect in the United Kingdom and the Commonwealth, in contrast to the scandals that have plagued other members of the royal family. Labour Party leader Keir Starmer expressed his well wishes for Queen Elizabeth's health and recovery. "Although the public still holds a positive view of her, the monarchy has faced challenges recently, such as Prince Andrew's involvement in a U.S. sex abuse case. Despite settling the lawsuit, questions about the monarchy's future remain. Additionally, British police have started investigating claims of honors being exchanged for donations to one of Prince Charles's charities."
