A British holidaymaker has tested positive for coronavirus while staying at a luxury TUI hotel in Greece.
The tourist, whose identity has not been revealed, was tested after landing in Corfu on August 3 as part of the country's randomised screening measures.
But despite Foreign Office advice saying coronavirus results are expected within 24 hours, the result only came back four days later.
It means the Briton - who allegedly showed know symptoms - could have unwittingly passed the virus onto other tourists and staff staying at the resort.
Travel provider TUI has since contacted the 140 guests enjoying their summer break at the hotel, as well as all guests expected in the near future
When the positive result was given on August 7 the holidaymaker and their entire group were made to isolate in their room at the five-star Blue Atlantica Grand Mediterraneo Resort.
They were then moved from the hotel into a special isolation hotel where they must spend the next 14 days, The Mirror reported.
Travel provider TUI has since contacted the 140 guests enjoying their summer break at the hotel, as well as all guests expected in the near future.
Those who flew on the same plane as the infected holidaymaker have also been contacted, and Greek authorities could order them to self-isolate for 14 days.
The website for the Atlantica Grand Mediterraneo Resort boasts of 'a truly luxurious retreat' that offers 'panoramic views over the Ionian Sea'.
The adult-only hotel has 270 rooms, and a seven night all-inclusive stay this month would cost around £2,374 for two people.
TUI confirmed the positive coronavirus result but said that no other guests or employees have reported any signs of illness.
A spokesperson told The Mirror: 'We are in regular contact with the customer who is showing no symptoms and continues to stay in a designated quarantine hotel.
'As soon as our team in Corfu became aware of this case, the customer remained isolated in their room until they were able to be moved to the specialist isolation unit.'
'The hotel has carried out extensive cleaning procedures in line with government advice and guests can continue to enjoy their holidays while
