Advertisement Queensland health authorities are scrambling to figure out how a fully vaccinated man tested positive after spending the full 14 days in hotel quarantine in Brisbane. The man, aged in his 40s, returned from China earlier this month and spent the required 14 days in quarantine, testing negative three times. Chief Health Officer Jeannette Young said the returned traveller left quarantine on July 12 and went to his home on the Gold Coast, but started feeling unwell the next day. He was tested at his GP, and the result was only returned yesterday, although it was not clear why it had taken so long to return a result.
