The Danish Royal Court has revealed that the Queen of Denmark tested positive for Covid-19 a second time this year.
After learning of the diagnosis on Tuesday night, Queen Margrethe II canceled her appointments for this week.
The 82-year-old monarch was one of 2,000 guests who attended Queen Elizabeth II’s state funeral on Monday.
She is Europe’s longest-serving head of state following the British monarch’s death.
She and Queen Elizabeth were third cousins, both being descended from Queen Victoria.
Queen Margrethe has been vaccinated against Covid and last tested positive in February this year when she presented mild symptoms.
In a statement on the palace website, a spokesperson said she would be recovering at Fredensborg Palace, north of Copenhagen.
Her son and heir, Crown Prince Frederik, and his wife Mary, the Crown Princess, will take her place in hosting members of the government, the Danish parliament, and Danish members of the European Parliament at a reception on Friday in Copenhagen.
In recent days, Queen Margrethe was pictured at several events in London to mark Queen Elizabeth II’s death.
At Westminster Hall on Sunday, on the eve of the late Queen’s funeral, she joined the crown prince to pay her respects at the lying-in-state.
At Westminster Abbey the following day, she sat in the same section as monarchs from other European nations, including King Carl XVI Gustaf of Sweden, Prince Albert II of Monaco, and King Philippe of Belgium.
In a letter of condolence to King Charles on the death of his mother, she wrote: “She was a towering figure among European monarchs and a great inspiration to us all.”
She became queen in 1972 at the age of 32 after the death of her father, King Frederick IX.
