Across the region, it's bound to raise questions surrounding the movement of positive cases.

Grampians Public Health Unit's clinical director Karen Aarons has offered up information for Stawell residents to gain an understanding of how exposure sites work.

First - here is an overview of what each exposure sites mean.

Dr Aarons said there were many factors which came into consideration when classifying an exposure site and the time it takes to notify the public.

"We go through a process before we list, or announce an exposure site," she said.

"As you could imagine it's really important that everything thing that is put forward is factual.

"It depends on how complex the case is to interview or gather information.

"It also depends on how big of a pandemic we are in at the time."

Dr Aarons said the Grampians Region Public Health Unit was aware there had been more exposure sites within the Ararat community.

"Those exposure sites are being processed..at the moment," she said.

"We anticipate they will be available further along in the day.

"What it really highlights is the fact there is further exposure.. go out and get tested if there is any sign of a sniffle."

Dr Aarons said exposure sites are listed based on the risk to the community.

"Where we feel comfortable there is no risk to the public or to the community in so much we've captured all the information we require internally to create safety and reduce risk as low as we can - there is no need for those sites to be listed because they don't pose a public threat," she said.

There have been no further exposure sites in Stawell and Dr Aarons said as far as she was aware at 2pm on Sunday there were no more cases in the Stawell area.

"We're still awaiting a few results, but essentially we're very comfortable where everything is at, at the moment, and it's all looking very promising," she said.

"Those again who need to be quarantining are doing so and all contacts have been contacted directly by the Public Health Unit at this time.

"There is no risk to the wider community. Everyone who has been deemed a contact has been contacted and the situation is in hand. When it's a risk to the community that's when it gets listed on the website in order to alert the public they need to act.

"Whilst we want to promote testing to anyone who has any symptoms in the context of the exposure site when all the contacts of that exposure site have successfully been contacted as there have been in cases in both Stawell and Ararat there's no necessity to be listed publicly."

Dr Aarons said throughout the pandemic, in other regional towns of Victoria, there have been misconceptions to think anything more of an exposure site.

"There is a process involved businesses liaising with Grampians Regional Public Health Unit," she said.

"We get in touch with premises and liaise about any cleaning that may be required to make their premises as safe as possible.

"If there they are open, they are open because they are safe."

Dr Aarons said, as of Sunday 2pm, despite the exposure site at Aldi which hadn't been formally listed but the Department of Health, the information that was on hand, and the cases in the region indicated there was a possibility no more exposure sites would be listed for Ararat.

"Obviously this advice could change, and very quickly, so we'll get the information out as soon as we can," she said.

"At this point in time, I'm not anticipating any additional exposure sites we aren't aware of.

"As we are getting busier with more cases across the region the interview (for contact tracing) has changed. It's been dynamic and changed to accommodate. There is an initial interview that is fairly brief that grabs the major safety issues to that case and their household and their surroundings.

"A deeper look can be done into acquisition if that's uncertain, sometimes it's to expand exposure sites if that's uncertain.

"Sometimes it can take a little longer (contact tracing) if further details are required. Sometimes banking records QR check-ins.. can all take time."

Dr Aarons said it was important the Ararat community were checking in with the QR code system.

"That data is used and is incredibly useful sometimes in determining whether something is an exposure site or whether someone has been a contact or not at a certain time," she said.
