On the late hours of Sunday night, the BBC announced that a Kensington Palace Source stated that Prince William, Second in line to the throne, had also suffered from Covid-19 around the same time as his father the Prince of Wales in April.
Unfortunately this started a debate, over whether we should have know then that he was suffering from the virus? The main argument for why he should have told us in advance was, due to the case of being completely open and transparent with the public. However, this neglects that most Royal illnesses unless they are very serious or interferes with any engagements are often hidden from the public in order not to cause alarm. It has also been stated by the source that this was the reason why Prince William kept it hidden until now.
I believe that he was right to keep it hidden. Due his character Prince William thinks very deeply about his role and position in life. So in order not to panic people with the knowledge that two heirs to the throne had contracted the virus that has killed millions world wide so far, he kept it hidden. So keeping this in mind it is clear that Prince William made sure that he kept to the law and isolated in Norfolk with his family. All while putting the public and its stability first. So it is because of this that I feel that Prince William did his duty and was thinking of the public when keeping it unannounced until now.
(This is my own opinion based on the information provided so far, what do you think?)
