Canadian Foreign Minister Melanie Joly said on Monday a rapid COVID-19 test that she had taken proved to be positive, adding she was working in isolation until the result could be confirmed.

"I have taken a rapid test and tested positive for COVID-19. Following public health guidelines, I am in isolation and will continue my work virtually, as I have been for a number of days, until I get the results of my PCR test," she tweeted.

Joly did not give further details. Her chief spokeswoman was not immediately available for comment.
