A statement from the family said: ‘Earlier this week the Countess of Wessex came into contact with someone who later tested positive for COVID-19.
“She has no symptoms, but follows all relevant government guidelines and is self-isolating at home. ”
A palace source said: “The Countess has not been in contact with the Queen or other royals outside of her own family since meeting the affected person.
“She will continue to isolate herself at home on government advice.”
It has been a busy week for Sophie and she has completed a number of royal engagements.
On Sunday, she ran 1.5 miles in the pouring rain alongside one of 45,000 runners in a unique London Marathon, which saw people take the distance on their own.
She joined Tomas, who was running to raise funds for Mencap, of which she is the godmother.
On Wednesday, she visited the National Space Center to mark World Space Week and learn more about their educational programs.
She joined Helen Sharman, the first British astronaut to go to space, as she chatted with students about the next generation of space travel.
The next day, she visited Stepping Stones School in Surrey to join the staff and students as they celebrated World Teachers’ Day.
Sophie and Prince Edward live in Bagshot Park in Surrey with their children, Lady Louise Windsor and James Viscount Severn.
She is said to be hugely popular with the royal family and has been described as their ‘secret weapon’ during the pandemic.
She met her future husband Edward in 1987 while working for Capital Radio in London, while he was dating her friend. Several years later, they reconnected at a charity event and began dating, their engagement being announced in January 1999.
Edward offered a two-karat oval diamond flanked by two heart-shaped gemstones set in 18k white gold – valued at over £ 100,000.

Sophie, at least in rank, is essentially under the Duchesses of Cambridge and Sussex in the family pecking order, but the Queen is said to be ‘fabulously fond’ of Sophie and greatly admires her work.
Kate is also seen as a staunch friend to her, as they demonstrated this week when they collaborated on a Zoom call with nurses from seven different countries on International Nurses Day.
