Prince Philip is expected to remain in the hospital for several more days because he's battling an infection, according to his youngest son, Prince Edward.

The Earl of Wessex updated the public on his father's health via an interview on Sky News. Edward said that the Duke of Edinburgh is comfortable and feeling much better at the hospital and they are keeping their fingers crossed that he completely recovers from his illness.

Edward also confirmed that his father is "a bit" frustrated at being confined to his hospital bed. However, he thanked the public for their well-wishes for the Queen's husband. Edward said that they've received a lot of messages and have been passing this on to the Duke of Edinburgh.

Philip, 99, was advised to check into the hospital on Tuesday, Feb. 16, after complaining of feeling unwell a few days before. Buckingham Palace said that his condition is not tied to COVID-19 and he remained in good spirits when he was admitted to the hospital.

While the public wonders if Queen Elizabeth will visit her sick husband, royal expert Arthur Edwards, who has photographed the royal family for decades, said that it won't be good news if the Queen turns up. Apparently, Her Majesty only visits if the situation is serious. Edwards said that until the Queen makes a trip to the hospital, then royal fans have little to worry about Philip's condition.

The veteran photographer also said that Philip likely asked his family not to go to the hospital. Aside from not wanting to be fussed over, there are stricter protocols at medical facilities due to COVID-19 and the Queen has to remain isolated at her castle in Windsor, despite having had the vaccine.

However, Prince Charles went to see his father last Saturday and spent around 30 minutes during the visit. The Prince of Wales has been the only visitor of the Duke of Edinburgh.

Royal expert Angele Levin said that Charles' gesture showed how much he truly cared for his father, despite their difficult relationship decades ago. The royal expert said that Charles has proven himself and has gotten in a better relationship with his parents in the last two decades.

In June 2021, the royal family will celebrate Philip's 100th birthday. Staff members at the Palace have been planning this celebration since late 2020 but they said Philip has been a reluctant celebrant that they are having a hard time setting up the party. As always, the Duke of Edinburgh refuses to be fussed over.
