The 94-year-old monarch was joined by her nephew, Prince William, on a visit to the Defense Science and Technology Laboratory in Porton Down, in southwest England. Neither wore face coverings, although they adhered to social distancing guidelines.
Buckingham Palace said the Queen decided not to wear a mask after consulting with her doctors and scientists at the Porton Down military research facility, which provides life support for the UK’s response to the Covid-19 pandemic.
“Specific advice on this visit was sought from the medical family and stakeholders,” added a real source.
Prince Charles’s office said at the time it was not known how he caught the virus due to his busy schedule of public events.
Britain is currently struggling with a spike in Covid-19 cases. British Prime Minister Boris Johnson on Wednesday imposed a three-tier Covid Alert system across England to try to stop the spread of the virus by implementing localized restrictions in some cities in the north and in the capital London.
In England, face coverings are mandatory in most indoor settings, including visitor attractions and entertainment venues, and in pubs and restaurants, unless you are sitting down to eat and drink.
