The Western Plains has seen another day of no new positive COVID cases as health officials shift their focus to keeping spread of the virus amongst young people at a minimum.

A total of seven new cases were identified in the Western NSW Local Health District (WNSWLHD) but all of them were from Orange.

Four of these cases have been identified as household contacts of previous cases while three have been identified as otherwise linked to previous cases.

WNSWLHD Chief Executive Scott McLachlan said a lot of the new Orange cases identified in recent days were children, proving how rapidly the virus spreads among demographics who spend a lot of time in close proximity.

"The Delta outbreak has seen a lot of children catching and transmitting COVID in their communities," Mr McLachlan said.

"We know children under 12 still aren't eligible to get vaccinated - it's being looked at but we're still not there yet - so it is important to protect them by making sure everyone eligible around them has been vaccinated."

Outside vaccination, Mr McLachlan said remembering all current public health orders, including wearing facemasks, regular hygiene and social distancing, inside schools and day care centres were equally important factors in minimising spread.

New venues of concern have also been added, including new casual contact locations in Lightning Ridge. The most up to date list of current venues of concern can be found on the NSW Health website. No new sewage detections were flagged in the past 24 hours

Testing numbers also climbed in the past 24 hours, with 3071 tests across the region.

"That's not a bad number but we would love to see that continue to climb as COVID continues to spread across the region," Mr McLachlan said.

Mr McLachlan also said turnaround times on tests had improved significantly in recent months.

When asked about people requiring a rapid negative result to attend elective surgery in hospital, he encouraged people to flag this with testing teams and they would do their best to ensure the lowest possible turnaround.
