The Prince of Wales, 71, revealed on Wednesday that he had contracted the virus
While self-isolating following his coronavirus diagnosis, Prince Charles virtually joined wife Camilla, Duchess of Cornwall, on Thursday night to show their appreciation for health care workers, clapping for those helping patients affected by COVID-19 in a viral hashtag initiative amid the ongoing pandemic.
In a split-screen video shared to Clarence House’s Instagram Story, the future king, 71, applauds from a room while Camilla, 72, can be seen clapping from an open window.
“Thank you to all 👏,” the caption on the video read, along with the hashtags #ClapForCarers and #ThankYouNHS.
The video came after Charles’ grandchildren — Prince George, Princess Charlotte and Prince Louis — also participated in the online campaign. Kate Middleton and Prince William‘s three kids made an appearance on the couple’s social media pages that same day, enthusiastically clapping to show support for health care professionals during the coronavirus crisis.
“To all the doctors, nurses, carers, GPs, pharmacists, volunteers and other NHS staff working tirelessly to help those affected by #COVID19: thank you,” the video was captioned, along with the hashtags #ClapForOurCarers, #ClapForCarers, #ThankYouNHS and #ClapForNHS.
In the sweet clip, Prince Louis, who turns 2 next month, stands between his older siblings — and sweetly glances up at them both as they all clap in unison. George, 6, and Charlotte, 4, smile throughout the video, with the little princess letting out a giggle towards the end.
The siblings even color coordinated for the surprise post, all dressed in shades of blue.
