Prince Charles has tested positive for COVID-19.

A rep for the Prince of Wales, who is the first senior royal to be diagnosed with the novel coronavirus, announced the diagnosis early Wednesday.

"The Prince of Wales has tested positive for coronavirus," the Clarence House statement to SBS News and other regional outlets said. "He has been displaying mild symptoms but otherwise remains in good health and has been working from home throughout the last few days as usual."

Per the statement, the Duchess of Cornwall was also tested, though she was determined to not have the virus. Both have been self-isolating in the days since being tested by the NHS in Aberdeenshire.

"It is not possible to ascertain from whom the Prince caught the virus owing to the high number of engagements he carried out in his public role during recent weeks," the rep added. A report from Sky News cites their royal correspondent Rhiannon Mills as having confirmed "doctors' most conservative estimate" on Prince Charles' contagiousness as having been ongoing since approximately March 13.

In their own report on Prince Charles' diagnosis, BBC News clarified that Buckingham Palace had confirmed the Queen last saw her son on March 12. She also "remains in good health" and is following all advice regarding the virus. That date also marked the most recent public engagement for Prince Charles, who attended a Mansion House dinner hosted by William Russell and George Brandis benefiting Australian bushfire relief.
