Queen Elizabeth II attended her first official engagements in person on Wednesday, following reports that she may have contracted coronavirus last week.
Two days after meeting the 95-year-old monarch, Prince Charles, her eldest son and heir to the throne, tested positive for Covid-19 for the second time.
According to advisers, his wife Camilla, the Duchess of Cornwall, tested positive as well, and the couple has been self-isolating since.
Buckingham Palace has not said whether the queen, who celebrated her 70th year on the throne this month, has done any Covid tests.
She hosted two top Royal Navy officers at her Windsor Castle house west of London on Wednesday, a week after the alarm.
The monarch was shown using a walking stick and wearing a patterned outfit as she greeted one of the officers in the Oak Room sitting room at the castle, according to a photo uploaded on the royal family’s Twitter account.
This came after she held two virtual audiences from Windsor the day before, meeting with freshly appointed ambassadors from Estonia and Spain via video link.
Meanwhile, Elizabeth hosted a reception for locals at Sandringham, her estate in eastern England, on the eve of the 70th anniversary of her accession to the throne.
It was her largest in-person public appearance since she spent a night in the hospital last autumn due to an unexplained health condition.
The royal family is embroiled in scandals when they return to routine royal responsibilities this week after curtailing them as the Omicron version swept Britain in recent months.
On Tuesday, the queen’s second son, Prince Andrew, reportedly resolved a sexual assault civil action in the United States for o12 million ($16.3 million, 14.3 million euros), which newspapers claim she will partially fund.
Meanwhile, police in London announced on Wednesday that they were looking into allegations that a Saudi tycoon was offered UK honors in exchange for payments to Prince Charles’ charitable foundation.
