She was tested on March 28th and got the results back yesterday.
Mary Lou McDonald was contacted yesterday to say she had tested positive for the Coronavirus - 16 days after getting the test.
She said she is no longer infected or infectious - which came after two weeks of feeling very unwell.
However, McDonald has had a setback in her recovery - developing post-viral pleurisy in her right lung.
She says she is responding well to medication and expects to be back at work next Monday.
McDonald has appealed to people to stay home and stay safe - saying you do not want to get this virus.
