| Updated March 3, 2021 Camilla, Duchess of Cornwall, gave an update on her father-in-law, Prince Philip, as the royal enters his third week of hospitalization for treatment of an infection. Camilla said while visiting the Community Vaccination Centre on Wednesday that the 99-year-old Duke of Edinburgh is “slightly improving,” according to reporter Chris Ship of ITV News. Buckingham Palace revealed for the first time last week that Philip, the husband of Queen Elizabeth, was battling an infection. The palace later issued another statement saying Philip was being transferred to a second hospital and also was being evaluated for a preexisting heart condition. Neither statement elaborated on the ailments.
