No new COVID-19 cases have been reported since Monday night, when the partner of a quarantine hotel cleaner with the disease was confirmed as a case.
Chief Health Officer Jeannette Young is urging anyone who visited two sites patronised by the man to get tested.
The venues are Bunnings Warehouse Acacia Ridge, between 2pm and 2.15pm on January 5, and Sunnybank Cellars, between 2.05pm and 2.15pm on January 6.
“The risk is low, but the risk is there so I really asked you to come forward,” she told reporters.
The man is the only known case since his partner tested positive on January 7, but Dr Young said it’s too early relax restrictions.
She said wearing face masks in public indoors and social distancing will be mandatory until at least January 22.
“Just remember the incubation period is 14 days, and there is no evidence that the incubation period for this new variant is any different,” Dr Young said.
“So we just have to wait, and we need to maintain all of the systems and processes we’ve all got in place as individuals to protect ourselves if this were to spread.
“So we just have to do what Queenslanders have done so brilliantly right from the start, in terms of following all the advice, and minimising the risk for everyone.”
Masks are mandatory in supermarkets, shops, indoor markets, places of worship, libraries, gyms and indoor recreational facilities such as cinemas and art galleries.
They also must be worn on public transport, in taxis and rideshare vehicles and should be carried at all times.
Deputy Police Commissioner Steve Gollschewski said while officers would enforce mask-wearing they may also offer people masks if they don’t have one.
“We will always give people the opportunity to comply with the directions,” he said.
“However, if people choose not to do that, there are strict penalties that apply and up to a $1300 fine could be imposed.”
Gatherings in private homes have been capped at 20 people and capacity is restricted at pubs, restaurants and cafes.
Dr Young also said an ongoing investigation into how the hotel cleaner became infected may not be conclusive.
Police are trying to recreate the entire timeline to pinpoint any specific breach.
“It still may be that we will never get to the bottom of whatever actually happened because it could be something quite incidental to do with how infectious disease is,” Commissioner Gollschewski said.
“But we will absolutely look at everything in the whole process.”
Dr Young also announced visitors from Victoria will only need to get tested on arrival and isolate if they have COVID-19 symptoms.
Queensland on Tuesday reported two cases of the virus in returned travellers – a father and daughter who arrived from Lebanon and are in hotel quarantine.
The total number of active cases in Queensland is 28.
