WINDSOR, England (Reuters). Queen Elizabeth, the longest-reigning monarch of the world, was tested positive for COVID-19 last Sunday. Although she is suffering mild symptoms, Buckingham Palace reported that Elizabeth expects to resume light duties next week.

Queen Elizabeth, 95, is now fully protected against the virus. She was admitted to hospital last October with an unknown condition. Her doctors advised her to stay in bed.

The Palace stated that “the Queen tested positive today for COVID.” Her Majesty has mild symptoms of cold-like illness but will continue to perform light duties at Windsor for the next week.”

The Palace stated that “She will continue receiving medical attention and will comply with all applicable guidelines.”

Charles, aged 73, is the heir to throne. He withdrew earlier this month from an event because he had contracted COVID for the second time. Sources at the Palace said that he was known to have met with the queen days prior.

Tuesday saw Elizabeth make a joke to royal household members that she was unable to move very well as she engaged in her first personal engagement since Charles’ positive test.

Elizabeth, world’s oldest monarch celebrated 70 years since her accession on the British throne.

She is the first British sovereign that has spent more than seven decades on the throne. This is a dynasty with a history dating back to Norman King William I, his conquest of England in 1066.
