Authorities are baffled as to how a mystery coronavirus cluster in Queensland began, as the state recorded another new case on Wednesday.
The new case is a close contact of another positive case from the Brisbane Youth Detention Centre at Wacol, in the city’s south-west.
Premier Annastacia Palaszczuk said she has ‘no real concerns’ about the new case and there is no broader risk to the community.
But there are concerns over the source of the cluster, and whether it has spread further, as authorities still don’t know how the original person diagnosed with COVID-19 contracted the infection.
The person resides in Forest lake and contact tracing is currently underway.
Queensland’s Chief Health Officer, Jeannette Young, said it was the 11th positive case related to the Wacol Youth Detention Centre.
‘We have not seen any community transmission due to any of the original five cases of those youth workers at the centre,’ Dr Young said.
‘We need to keep alert for that. There is still a risk over the next week that we will see that because those people were out and about in the community.’
While it is still unclear how the cluster began, Dr Young on Tuesday said it could be related to one of the women who allegedly lied on their border declaration passes and snuck into the Sunshine State after visiting Victoria.
Diana Lasu, 21, Olivia Winnie Muranga, 19, later tested positive for coroanvirus sparking fears of a huge outbreak.
Both women and their friend Haja Timbo, 21, have been charged under the public health act with one count each of providing false or misleading documents and fraud. If convicted they face up to five years in jail and fines of up to $13,345.
Health authorities are still investigating a ‘missing link’ between the girls and the detention centre cluster, with Dr Young saying the case linking them is yet to be idenfitifed.
‘Where did they actually originally get it from?’ Dr Young said.
‘Which means we could have more cases out there in the community that have resulted in this cluster.’
‘Clearly not a lot because we’re doing so much testing, but it means we’ve got to keep those very high rates of testing in place.’
Five workers from the detention centre, and five family members, have now tested positive.
Dr Young said there is still risk of community transmission but there has not been any from the original five cases from the detention centre.
‘This case was a known contact of one of those other cases, so we will now work through to see whether there’s any additional work we need to do related to this new case,’ Dr Young said.
‘We have not seen any community transmission due to any of the original five cases of those youth workers at the centre. We need to keep alert for that.
‘There is still a risk over the next week that we will see that because those people were out and about in the community.’
More than 20,000 Queenslanders presented for testing in the past 24 hours. There are currently 16 active cases in the state.
‘The highest level of testing results,’ Ms Palaszczuk said.
There have been 64 flights into the state in the past day with 2,904 travellers on board – only two have been refused entry.
Up to 3,417 vehicles have been stopped at the border with 107 people turned back and 455 people forced into hotel quarantine.
Anyone who lives in Brisbane, Logan, West Moreton and Ipswich are being urged to get tested immediately.
