November 3, 2020 -- The Duke of Cambridge contracted COVID-19 earlier this year but did not reveal the diagnosis to avoid alarming the nation, it was reported.
Prince William reportedly tested positive in April, shortly after his father, Prince Charles.
According to The Sun , which first reported the story, Prince William was treated by palace doctors, and self-isolated at the family home, Anmer Hall, in Norfolk.
The newspaper quoted a source who said: "William was hit pretty hard by the virus – it really knocked him for six. At one stage he was struggling to breathe, so obviously everyone around him was pretty panicked."
In late March, Prince Charles tested positive for COVID-19 and self-isolated for 7 days at Balmoral Castle in Scotland with his wife, Camilla, Duchess of Cornwall, who tested negative.
The 71-year-old heir to the throne was said to have experienced mild symptoms.
On March 27, English Prime Minister Boris Johnson revealed he had tested positive for the coronavirus.
The prime minister was admitted to hospital on April 5. He was later moved to intensive care.
The UK experienced its worst day for deaths from COVID-19 just days later, on April 8, when a record 1,445 people died with the disease in a 24-hour period.
Prince William has not publicly confirmed that he had the SARS-CoV-2 virus. However, according to The Sun, he reportedly commented privately at an engagement, "There were important things going on and I didn’t want to worry anyone."
Kensington Palace declined to comment on Sunday over the media reports but did not deny the claims, Sky News reported.
The reports of Prince William's diagnosis emerged days before England is due to enter a second national lockdown, with 4 weeks of restrictive measures designed to stem a growing number of cases of COVID-19.
Johnson announced at a Downing Street news conference on Saturday that pubs, restaurants, gyms, non-essential shops, and places of worship must close.
He said nobody wanted to impose such measures, but no prime minister could ignore the expert evidence of a "national problem", with deaths and hospital admissions continuing to double.
