The 77-year-old royal admitted she was still “coughing” as she resumed her duties after canceling several appearances due to the illness.

The palace announced on November 5 that Camilla had fallen ill with a chest infection and would be canceling her plans for the week. The news came a few days after she and Charles had returned from their trip to Australia and Samoa.

Camilla has had to cancel public engagements in past years due to health issues, including for a chest infection in 2019, and an ear infection and sinusitis in 2012. No further details regarding the severity of the Queen's illness or the treatment she is receiving have been released, as is the norm with Royal medical issues.
