Sophie, Countess of Wessex was today self-isolating at home after coming into contact earlier this week with someone who has now tested positive for coronavirus.
The 55-year-old wife of Prince Edward is not experiencing any symptoms of Covid-19 but is said to be following all relevant Government guidelines.
Sophie is not thought to have seen any members of the wider Royal Family since she met the unnamed person who has subsequently tested positive.
Prince Charles caught coronavirus in March but later recovered from a mild form of the illness following self-isolation at his Scottish residence of Birkhall.

A Buckingham Palace spokesman said: ‘Earlier this week the Countess of Wessex came into contact with someone who has subsequently tested positive for Covid-19.
‘She is not experiencing any symptoms, but is following all relevant government guidelines and is self-isolating at home.’
When asked if she had been in contact with the Queen or any other members of the Royal Family, a source added: ‘She certainly hasn’t seen any of them this week. The last time would have been before she saw the person who has subsequently tested positive.’
Over the past week Sophie has carried out royal engagements across the country, starting in Vauxhall City Farm, London, and most recently at the National Space Centre in Leicester.
Last Thursday she was at the farm in the capital with her husband as they celebrated the start of Black History Month with staff.
The Earl and Countess met some of the schoolchildren participating in a programme of educational activities and heard from teachers and students who shared stories and poems about important figures in black history.

On Sunday, Sophie was one of 45,000 people across Britain who were running, jogging and walking their own version of the London Marathon in torrential rain.
She gamely donned her exercise gear to join Tomas Cardillo-Zallo, a member of Mencap’s Learning Disability Running team, for the first 1½ miles of his virtual race.
Sophie has been patron of the charity since 2004 and said she decided to join the 29-year-old, from Sutton in Surrey, as a show of support for Mencap and its work to change attitudes towards those with learning disabilities.
She ran the distance to reflect the fact that 1.5million people in the UK live with a learning disability – facing daily challenges and requiring help with everyday tasks.
Sophie joined Mr Cardillo-Zallo – one of 312 people running in support of Mencap – on the Long Walk in Windsor Great Park, for the first section of his 26-mile route.
She said on Sunday: ‘It was an honour to join Tomas even just for a small part of his triumph today, as he completes the London Marathon in support of Mencap.
‘Tomas has shown what people with a learning disability can achieve with the right support. He is an inspiration.’
The following day the Royal went to Stepping Stones school in Hindhead, Surrey, to mark World Teachers’ Day.
She was welcomed by Her Majesty’s Lord-Lieutenant of Surrey, Michael More-Molyneux.
But on October 7 she travelled up to the National Space Centre in Leicester to to mark World Space Week,
She was joined by astronaut Helen Sharman – the first Briton to go into space – at the Centre, which had recently re-opened with social distancing measures in place.
The Countess met a small number of students participating in the National Space Academy’s Space Engineering Course.
They told her about the key role the Centre plays in space education in the United Kingdom.
