As was the case at the beginning of the pandemic, visitors to the hospital won't be permitted. Volunteers and way-finders also won't be on hospital grounds.

There are exemptions in place on a couple of grounds, those being caring and compassionate circumstances; supporting women in labour, providing care for children in hospital and for palliative care.

The Western NSW Local Health District says the move is a precautionary step aimed at protecting the safety of staff and patients.

"This decision has not been made lightly. As a priority, we must always ensure we are not putting our vulnerable patients and critical health services at risk of a COVID-19 exposure," a Western NSW LHD spokesperson said.

The same restrictions will apply at the Orange Hospital as well as Multi Purpose Services (MPS) in Blayney and Molong.

The strict visitor restrictions placed on the region's health services comes on the back of the confirmed positive case at Blayney on Tuesday.

A single worker at the Nestle factory returned a positive COVID-19 test on Sunday following exposure to the virus via a pet food delivery driver last week.

The positive case in Blayney has been in isolation since Sunday, as have immediate close contacts.

Western NSW LHD said investigations and contact tracing into the positive case are ongoing, and is encouraging anyone with symptoms to get tested.

"We encourage everyone to continue to remain vigilant. COVID-19 is still circulating in our communities," the spokesperson said.

COVID-19 testing is available at several locations around the region.
