Queen Camilla has had to withdraw from a number of scheduled engagements this week due to a respiratory infection, Buckingham Palace announced on Tuesday, November 5.
No further details have been provided regarding her illness or treatment, but she is believed to be resting at home under medical supervision.
The Duchess of Gloucester will take over on behalf of the Queen for the annual Remembrance Field dedication at Westminster Abbey on Thursday, according to the BBC.
The Queen will also not attend the Buckingham Palace reception for Olympic and Paralympic athletes, which will be hosted by King Charles later that evening.
“Her Majesty the Queen is currently unwell due to a chest infection, for which her doctors have advised a short period of rest.
With great regret, Her Majesty has been forced to withdraw from her engagements for this week, but she is very hopeful to recover in time to attend the memorial events over the weekend.”
