Prince William, second in line to the British throne, contracted COVID-19 in April and suffered breathing difficulties, The Sun newspaper reported on Monday.
According to the tabloid, The 38-year-old prince did not want to talk about his illness at the time because “important things were happening and he did not want to worry anyone.”
Following the slogans, William quarantined himself at the Anmer Hamm family home in eastern England, but continued his work via phone or video conference.
Contacted by AFP on Monday, Kensington Palace, the official residence in charge of communication for the prince, did not want to comment on the information.
According to The Sun, William was “Affected by the virus quite harshly.”
“At one point, he was having trouble breathing, so everyone around him was obviously quite scared,” A source who asked to remain anonymous told the newspaper.
William’s father, Prince Charles, 71, had announced on March 25 that he had contracted the virus with mild symptoms from which he has since recovered.
The eldest son of Queen Elizabeth and heir to the crown was isolated for seven days at his Scottish residence with his wife Camilla, Clarence House announced in a statement at the time, and continued to “telecommute as usual.”
