A member of the Queen's Buckingham Palace staff has tested positive for Covid-19 with the case being confirmed while Her Majesty was in residence at the palace, UK media have reported.
The Queen, 93, left the palace late last week after the diagnosis, moving to Windsor Castle where she remains, reportedly in good health.
The unnamed aide fell ill earlier last week and then tested positive for the virus.
Every member of the palace's staff they came into contact with has since been placed in self-isolation, the Sun reported.
It was not known what contact, if any, the worker had with the Queen.
