Link missing between virus cases
The new coronavirus case is connected to another announced two weeks ago, with the missing link between the pair likely still in the community.
Genomic testing on Friday confirmed the 26-year-old's case was linked to a hospital worker whose infection was announced on March 12.
Queensland Chief Health Officer Dr Jeannette Young said it is likely that an unidentified intermediary had passed the virus onto the Stafford man.
"We will know more in the next 24 hours, but in the meantime, those identified as visiting the locations in today's Public Health Alert should immediately get tested and isolate until you receive your results," she said in a statement on Friday night.
Health authorities are tracking down close contacts of the man, who will have to undergo quarantine.
New case sparks another hospital lockdown
Brisbane's hospitals were put in lock down for the second time in a fortnight following news of the latest case.
Premier Annastacia Palaszczuk has locked down hospitals, aged care facilities, prisons and disability services for the next three days to stop the virus spreading to vulnerable people.
Everyone in the Brisbane City and Moreton Bay council areas are being urged to wear masks in crowded places and socially distance.
"It is absolutely imperative over the next few days if you are sick and unwell to stay home and go get tested, it is absolutely critical we do this over the next two to three days," Ms Palaszczuk told reporters.
Dr Young said the man is being treated in Royal Brisbane and Women's Hospital.
His housemates in Stafford are all self-isolating and getting tested.
The man started feeling ill at work on Monday.
"Anyone who's been to any of these venues during those specific timeframes, I want you to come forward and get tested, whether or not you've got symptoms, and to remain in isolation until you get a negative result," Dr Young said.
