CAMILLA cancelled a day at the races yesterday as she struggles to overcome Covid.
The Duchess, 74, had been due to present a trophy at Cheltenham but sources said she was “pacing herself”.
She tested positive a month ago.
On Tuesday royal watchers said she appeared tired on a visit to an Irish cultural centre in West London.
Last week she told a reception: “I can’t get shot of it.”
She added: “Probably my voice might suddenly go and I might start coughing and spluttering.”

There was an outbreak among staff at Windsor Castle in February.
Camilla was due to present the winner of The Betway Queen Mother Champion Steeple Chase and visit the paddock.
