Almost two years after kicking COVID-19, King Charles III found himself behind the palace walls once again with the virus. It seemed that he was none too thrilled with the situation, with his wife, Camilla, Queen Consort, telling those present at a royal engagement that her husband was not exactly happy that he had to self-isolate and was finding it "a bit tiresome" (via The Guardian).

Charles' official X account broke the news of his second COVID-19 infection. "This morning The Prince of Wales has tested positive for COVID-19 and is now self-isolating," the post read. "HRH is deeply disappointed not to be able to attend today's events in Winchester and will look to reschedule his visit as soon as possible." The comments were, once again, filled with well-wishes from royal watchers. Some, however, criticized Charles for no longer wearing a mask during public engagements.

This time around, it wasn't clear where the king might have contracted the virus, but there were some concerns that he could have infected his mother, Queen Elizabeth II, since he had spent time with her shortly before his diagnosis. Buckingham Palace revealed that the queen's vaccinations were up-to-date and that she would be tested for the virus daily. Charles' vaccinations were presumably up-to-date, as well — in December 2021, he and Camilla were encouraging the public to get their booster shots after they made sure to get their own.
