Sunday officially marked 100 days since Albury Wodonga Health last recorded a positive COVID-19 case.

The region's other major testing organisation, Murrumbidgee Local Health District, recorded four cases in August but all were Wagga residents.

In July, three Lavington residents from the same family tested positive to coronavirus after members returned from Melbourne.

COVID Services team leader Linda Todhunter, who heads up the Wodonga drive through clinic, said staff were confident in their abilities to detect and treat any positive cases that might arise.

"We have a dynamic team who know what to do and have learnt along the way," she said. "Right now it's solid, as in what else are you going to throw at us, we're ready for it."

Since February, Albury Wodonga Health more than 15,000 tests have been processed through the organisation. Testing is also available through some GPs.

COVID Services nurse unit manager Caroline Grealy said the relatively quiet period allowed the service to focus on solidifying their structures and systems, including setting up a local COVID tracing team.

"We can activate this when we need to, we're prepared, I feel that as an organisation we're very prepared," she said.

"These processes and procedures that have been developed can just sit in an archive, we can stand it down eventually and it can sit there in the archive and next time it won't have to be developed."

Mrs Grealy said it was important the community stayed cautious and alert.

"I will always encourage anyone to take the precautions you think you need to take, if ever there's a question mark, just wear the mask it's not that invasive," she said.

"You do get a bit complacent I think and I imagine the community complacent as well with no community transmission for a time but it's important to keep those standards high."

Infection control consultant Leisa Bridges said the service's dedicated outpatient clinic handled the most recent cases successfully.

"We're very conscious of the mental health aspect and social isolation so we've really tried to make sure that's all covered off as well and to ensure they have the resources to stay at home," she said.
