(CNN) -- British health care workers got a round of applause Thursday from some of the youngest members of the royal family.
A video on Kensington Palace's official Instagram page shows Prince William and Kate Middleton's children clapping for them.
The cheers from Prince Louis, Princess Charlotte, and Prince George are part of a bigger social media campaign called "clap for carers.”
Many members of the royal family, including Queen Elizabeth II and Prince Harry, have also shared messages of support amid the COVID-19 outbreak.
Those messages became even more vital after Prince Charles tested positive for the virus Wednesday.
It is believed the video of the children was shot at Anmer Hall in Norfolk.
The Duke and Duchess of Cambridge moved their family from Kensington Palace in London to their country house in Norfolk because of the outbreak.
The British government often considers the country's national health service one of its proudest achievements.
