A 17-year-old female student at Indooroopilly State High School in Brisbane’s inner west has tested positive for COVID-19.
Queensland Health Minister Yvette D’Ath said the case was infectious in the community for three days, since the 27 July.
“There is very little more information at this stage. We have yet to receive genomic sequencing on which variant the case has or whether it is linked to other outbreaks.”
Ms D’Ath said the student’s family of five people are being tested and contact tracers are working quickly to identify any further transmission.
She said authorities may take further action, once they establish the source of the infection.
“Because it is unknown or unlinked to other confirmed cases, masks are more important than ever, as well as social distancing and good hygiene.”
The acting executive principal of the school, Derek Weeks, said cleaners will deep clean the school as a precaution.
Queensland chief health officer Dr Jeanette Young said none of the recent outbreaks were connected to the school.
“I am struggling to understand how she acquired it,” she said.
Dr Young said genomic sequencing results are expected later on Friday.
The CHO said the state had been responding to an increased number of COVID-19 cases in recent weeks.
“We do know that we have had 13 incursions of the virus into Queensland over the last six weeks,” she said, urging people to get vaccinated.
“We know that in any particular outbreak, someone with can get infected, not have symptoms and then spread the virus to someone else, which is why it’s critically important that we all remain very, very cautious until the vast majority of people have been able to be vaccinated.”
In Queensland, 37 per cent of adults have received one dose, 17.1 per cent have received two doses. The number of vaccine doses administered in the state is 887,335.
Nationally, 17.7 per cent of people over the age of 16 have received two doses.
