Prince William is appropriately concerned for his father, Prince Charles, and his grandparents, Queen Elizabeth II and Prince Philip, during the COVID-19 pandemic. The disease can be especially difficult for seniors to handle.

The Prince, accompanied by his wife, Kate Middleton, voiced his concerns and reflected on his father's earlier COVID-19 diagnosis in a new interview with BBC Breakfast on April 17.

Looking back on Prince Charles's case of COVID-19, Prince William said:

"I have to admit at first I was quite concerned. He fits the profile of somebody — the age he is at, which is, you know, fairly risky.

"And so I was a little bit worried, but my father has had many chest infections, colds and things like that over the years. And so I thought to myself, if anybody’s going to be able to beat this it’s going to be him."

The Duke of Wales, 71, fortunately recovered not too long after his diagnosis in March.

But Prince William also has his grandparents, Queen Elizabeth and Prince Philip, on his mind during the crisis.

"I think very carefully about my grandparents who are, you know, at the age they’re at, and we’re doing everything we can to make sure that they're, you know, isolated away and protected from this," he said.

The Queen turns 94-years-old next week, while Prince Philip turns 99 in June.

"But it does worry me, you know, what’s going to happen to a lot of the vulnerable people and the high-risk people who are going to potentially have to isolate away for quite some time, and the impact that’s going to have on them and on families up and down the country having to do that," the Prince added.

The Prince was also asked to reflect on the range of emotions that accompany trauma and a pandemic.

"Trauma comes in all sorts of shapes and forms and we can never know or be prepared for when it is going to happen to us," he said.

"People are going to feel angry, they’re going to feel confused; they’re going to feel scared. That is all normal feelings. And that is, unfortunately, all part of the grieving process."

William and Kate currently remain at their home in Norfolk, while the Queen and Prince Philip are at Windsor Castle amid the crisis.
