Queen Elizabeth is in good health and doing fine. Buckingham Palace released a statement to assure the British public of Her Majesty's status after her eldest son, Prince Charles, confirmed that he tested positive for COVID-19.

The last time the Queen was with Prince Charles was on March 12, during an investiture ceremony at the palace. Since the outbreak, Her Majesty has been closely following the government's advice regarding her health and welfare, according to a spokesperson.

Doctors said that Prince Charles might have been contagious on March 13, or just 24 hours after he was with his mother. A spokesperson from Clarence House said it was not possible to determine where Prince Charles might have been exposed since he has carried out a number of royal engagements in the past weeks.

The confirmation came just a few days after Prince Albert of Monaco also announced he is COVID-19 positive. Both princes were in attendance at the WaterAid summit last March 10 i London. Prince Albert sat opposite Prince Charles.

Camilla, the Duchess of Cornwall, has also been tested for coronavirus and is negative. The couple are in self-isolation at their country home in Scotland. Doctors say that Prince Charles is exhibiting mild symptoms only but they had to be tested since they met the criteria required by the NHS. Prince Charles and Camilla are both in their 70s.

Meanwhile, it's unclear if Queen Elizabeth has been tested for coronavirus but she and Prince Philip have been in isolation at Windsor Castle since Thursday, March 19.

Only eight people are allowed to see and tend to the aging royals as a precautionary measure. On normal days, over 100 people work for the Queen on a daily basis.

Queen Elizabeth is still conducting her official functions and she had her weekly audience with Prime Minister Boris Johnson, albeit by phone. The Royal Family social media account posted a photo of the Queen and the prime minister talking to each other.

Her Majesty is also coordinating with government officials and health workers, as well as her royal staff, through Skype or FaceTime. Reports said that she will release another unprecedented televised national address in the coming days to assure the British people that they will get through this public health crisis.

The Queen is expected to stay in Windsor even after her Easter holiday. She and Prince Philip has doctors on standby as well. Both royals are in their 90s.
