Ms Morgan-Wicks says she is asymptomatic and will continue working in the role, as well as in her position as health department secretary.
She returned a positive result on Tuesday afternoon after being tested in the morning.
"I am asymptomatic but undertook a PCR test... following a member of my household developing mild symptoms and being confirmed as a positive case," she said.
Ms Morgan-Wicks said she was "currently well".
Members of her household are in quarantine as close contacts.
