Camilla, the Queen Consort, has tested positive for COVID-19, according to Buckingham Palace.
King Charles' wife had been forced to postpone a visit to the West Midlands on Tuesday, with the palace initially saying she had contracted a "seasonal illness."
"With regret, she has therefore cancelled all of her public engagements for this week and sends her sincere apologies to those who had been due to attend them," the palace said in a statement.

Camilla also tested positive for COVID-19 in February 2022 and is vaccinated.
The 75-year-old became queen consort when Queen Elizabeth II died in September and her eldest son, Charles, became king.
