Charles' wife Camilla, the Duchess of Cornwall, 72, tested negative for coronavirus but will remain in self-isolation until the end of the week, according to the BBC.
A palace official said the prince was in good health and was following the government’s restrictions, the network reported.
The prince had last seen his mother, Queen Elizabeth II, on March 12, after an investiture ceremony for public awards in London, CNN reported. The queen, 93, has canceled her engagements and has moved to Windsor Castle, where she will remain through Easter.
Several high-ranking British officials have tested positive for coronavirus in the past week, including Prime Minister Boris Johnson and Health Secretary Matt Hancock.
