Roald Dahl’s Marvellous Children’s Charity was set with the intent of using the Charlie and the Chocolate Factory author’s legacy to help sick youngsters.

The organization funds 78 specialist nurses who care for 21,000 children at hospitals across the U.K.

However, they have launched an appeal for donations during the coronavirus pandemic to ensure they can continue helping children with serious illnesses.

In a video message this week, Camilla said: “I have seen for myself the incredible work of Roald Dahl’s specialist nurses as they look after children with complex life-long illnesses.

“In these challenging times, nurses in every part of the country are giving their all to care for patients.”

She added: “I know⁠—particularly now⁠—that you make all the difference in the world to these children and their families.

“Thank you from the bottom of my heart.”

The charity said on Twitter: “Such a wonderful video from The Duchess of Cornwall to support our #RoaldDahlNurses.

“Every seriously ill child deserves a Roald Dahl Nurse.”

Camilla’s intervention comes after her husband Prince Charles contracted coronavirus himself, suffering mild symptoms during a week of isolation.

The duchess was forced to spend two weeks alone at Birkhall, the royal residence in Scotland where they have been sitting out the pandemic.

The prolonged period of solitude ended just in time for the couple to spend their anniversary together.

Prince Charles spoke of his struggle with COVID-19 in the days after he was given the all-clear, but while Camilla was still in isolation.

He said: “Having recently gone through the process of contracting this coronavirus, luckily with relatively mild symptoms, I now find myself on the other side of the illness, but still in no less a state of social distance and general isolation.

“As we are all learning this is a strange, frustrating and often distressing experience when the presence of family and friends is no longer possible and the normal structures of life are suddenly removed.

“At such an unprecedented and anxious time in all our lives, my wife and I are thinking particularly of all of those who have lost their loved ones in such very difficult and abnormal circumstances, and of those having to endure sickness, isolation and loneliness.”

Prince William gave an indication of how the diagnosis rocked the royal family and took its toll on his father’s mental health.

In a BBC interview, he said: “I have to admit at first I was quite concerned.

“He fits the profile of somebody of the age he’s at, which is you know fairly risky, and so I was a little bit worried.”

He added: “But my father has had many chest infections, colds, and things like that over the years, and so I thought to myself if anybody is going to be able to beat this it’s going to be him.

“And actually, he was very lucky, he had mild symptoms.

“I think the hardest thing he found was having to stop and not being able to go and get a bit of fresh air and go for a walk. He’s a mad walker, loves his walking.

“So I think he found it quite difficult. especially also with his mental health—being sort of stuck inside and not being able to go for walks.”

The coronavirus continues to be an issue in the U.K., with the country reporting the third highest number of cases, as the following graph from Statista indicates.
