The royal staff at Windsor Castle is ensuring the protection of Queen Elizabeth from coronavirus by implementing and following rigid quarantine measures. As the monarch and her husband, Prince Philip, belong to the high-risk sector against the virus, extreme precautions have, reportedly, been taken to ascertain that the Queen is safe. 

The 24 servants tasked to help out Queen Elizabeth and Prince Philip are divided into two groups and follow a rotating schedule. Each group is required to follow a "three weeks on, three weeks off" system.

This system requires the Queen's workers to stay two weeks at home and the third week for quarantine and testing for coronavirus, including regular temperature checks. If they are in the clear, then they can come to Windsor Castle and then work for three weeks without going home to their families until their shift is over. 

The royal aides are taking no chances for the virus to reach Windsor Castle. As such, Queen Elizabeth and Prince Philip are to remain in isolation indefinitely. The public tours at the estate have also been closed this year amid concerns of a virus spread.

According to Buckingham Palace, the Queen's calendar of events has been cleared as she withdraws from public life to safeguard her health. It is expected that she will be out of the circuit for months while the rest of the family will be taking over her royal duties. 

Prince Philip, on the other hand, has been retired from public life since 2017. However, his health is still at risk since he has pre-existing medical conditions.

Queen Elizabeth was supposed to travel to South Africa in the fall. But she is leading by example by following the government guidelines which disallows those in the vulnerable sector to be exposed to people. 

The Queen almost had a close call after Prince Charles contracted the virus in early April. Her son met with her a few weeks before he found out he was positive for coronavirus. Prime Minister Boris Johnson also had coronavirus and he met with the Queen in person before she left for Sandringham to isolate.

Prince William said that they royal family wants to ensure the protection of Her Majesty. Tony Johnstone-Burt, Queen Elizabeth's Master of the Household, is tasked to carry out this protection. In April, the master wrote a memo to the royal workers reiterating that Her Majesty's health, and that of her husband's should be safeguarded at all times.
