Queensland Premier Annastacia Palaszczuk and Doctor Jeanette Young have announced Brisbane locations on alert after a cleaner has tested positive for coronavirus.

Ms Palaszczuk announced the state has recorded two new cases overnight, one being a child in hotel quarantine and the other, a cleaner who works at a quarantine hotel.

The cleaner returned a negative result from a routine coronavirus test on December 29, but later developed symptoms and came forward for testing.

Ms Palaszczuk and Doctor Jeannette Young said the cleaner has cooperated fully.

“We have deemed her infectious period to be from the 2nd of January onwards,” said Dr Young.

Dr Young announced locations now on alert that the cleaner travelled to during her infectious period.

Anyone who has been to the following locations – regardless of whether they have symptoms or not – should get tested and isolate until they receive their result.
