Sparrow Early Learning CEO John Bairstow said the centre was working to track down children who may have come into contact with the infected staff member at their Karana Downs centre.

"We are working with public health to identify which children need to go into quarantine," he said.

"Parents have been notified that the centre has closed and why.

"At the moment contact tracing is being performed."

Mr Bairstow said the centre held up to 67 children.

Three female educators at the Karana Downs site were tested for the virus after one of their husbands returned a positive test on Friday March 13.

He said two educators socialised with a female colleague and her husband on the weekend of March 7-8 before the educator's husband tested positive to COVID-19.

"They were separated from the children and sent home," he said.

"(The man's) wife's test was negative. One of the other educators came back negative but one returned a positive test last night.

"A lot of educators are upset because a colleague has been diagnosed, we now have to go through the tracing process.

"The centre has been cleaned on the weekend.

"As the Prime Minister said childcare is an essential service, we have lots of families working for the emergency services who rely on our care so we hope to reopen as soon as (Thursday)."

Queensland Health Minister Steven Miles said today there were 94 cases in the state, up from 78 yesterday.

How to talk to young children about COVID-19

Early childhood health and wellbeing specialist Dr Alice Brown, from the University of Southern Queensland, said educators, parents and teachers needed to keep conversations around COVID-19 clear, honest and simple with young kids.

"While a number of people in our society will get COVID-19, the research says we also have to be aware of the mental health and psychological impact that this is having on all of our young children," she said.

"When parents and educators are talking to young children, especially those four and under, about COVID-19, it's about being honest and accurate, responding in a calm and reassuring way and ensuring the tone of your voice is calm.

"It's important to explain that it's similar to a cold, because they understand that reference, and that some children are getting sick and that adults are trying to protect others from getting colds and becoming unwell.

"It's also good to let them know we can do a lot of things, like washing our hands and covering our mouths when we cough, and that sometimes we might not be around people who are sick and that is about protecting ourselves and each other."

Dr Brown said encouraging children to ask questions was also important.

"Be patient with children and ask them what they know and when parents and educators are responding to questions it's also important that they give themselves a minute to collect their thoughts and respond, because young children pick up on emotion a lot," she said.

"Let them know the adults around them are here to protect them and keep them safe."
