Murrumbidgee Local Health District confirmed a resident of the Albury local government area with underlying health conditions succumbed to the virus prior to 8pm on Monday.

"Murrumbidgee Local Health District extends our sincere condolences to the person's family and loved ones, and the whole Albury community," the authority said yesterday.

Another 10 cases of the virus were detected in the MLHD during the 24 hours to 8pm on Monday, with the region's tally for the Delta outbreak now standing at 115.

It comes after 45 new cases were detected in the region in the three days prior.

Seven of the newly-diagnosed COVID patients are Albury residents, with three linked to known cases and four still being investigated. Further inquiries are being carried out after a resident in both of each the Federation and Edward River LGAs were found to have the virus.

The remaining case - a resident of the Greater Hume area - is a household contact of a previously-announced case.

The strong message from the health authority is to get tested, seek a vaccination and for four of the region's council areas, stay close to home.

"Residents in Albury, Edward River, Greater Hume and Murray River LGAs are urged to limit their movements in and out of the community at this time and widespread COVID-19 testing is critical," the MLHD said.

"Anyone currently experiencing, or who has recently experienced even mild cold-like symptoms is asked to come forward immediately for testing."

A sobering 18 new exposure sites in several southern Riverina communities were listed by NSW Health, and anyone who visited the venues at specified times needs to seek out a COVID-19 test and isolate until receiving a negative result.

In Albury, they include an Apco service station, Bunnings, Chemist Warehouse, Connor, Dan Murphy's, Service NSW, Centrelink and cafe The Proprietor.

The Thurgoona Coles and Woolworths stores have had new timeframes added, and Mayo's Chemmart Pharmacy and the Albury Waste Management Centre are also now venues of concern.

The western Riverina community of Barham also has exposure sites at the local post office, IGA, shoe shop and two pubs.
