More than 1,000 southeast Queensland families have been ordered to quarantine for two weeks after they were potentially exposed to the coronavirus by a four-year-old girl infected by an interstate truck driver.
The girl tested positive to the virus on Friday, and is the daughter of a close family friend of a Logan truck driver who was diagnosed with the virus on Thursday after being active in the community for five days.
All other close contacts of the driver have so far tested negative to the virus.
The girl was likely infectious in the community for two days, chief health officer Jeanette Young told reporters on Saturday, and attended the Boulevard Early Learning Centre in Windaroo.
A hundred families whose children attended the same centre have been forced into 14 days of home quarantine.
Some 960 families of children who attend Windaroo State School must also isolate for 14 days, after the school was attended by a student who also went to before and after school hours care at the daycare centre.
Dr Young said she believed the risk posed by the girl was "under control", but is more concerned about the truck driver, who was active in the community for several days with a high viral load.
A public health alert has also been issued for Beenleigh Marketplace, with those at the centre between 10:30am and 11:45am on Monday asked to get tested and isolate until they receive a negative result.
One overseas acquired case was also diagnosed in hotel quarantine on Friday.
