Karl is 59 and revealed his condition while calling into a program on Austrian TV channel oe24. He said that his flu-like symptoms began a week ago, per People magazine:
“It’s annoying, but I’m fine. It’s not the Black Plague. I thought it was the usual flu. When a friend called me that he had a positive test at a congress in Switzerland, I was also tested. I have to expressly praise the Austrian authorities because they act with measure and aim. Panic mood is not appropriate.”
Karl isn’t the only royal to face this question. Spain’s King Felipe and Queen Letizia have recently been tested. Queen Elizabeth is reportedly seeking refuge in Windsor Castle, and Prince Harry and Meghan Markle both made it back to Canada ahead of the closure of the country’s borders.
