New South Wales police has conducted an inquiry, and has found no wrongdoing, at an aged care facility in Western Sydney where a worker has tested positive to COVID-19.
"It is understood the woman was not symptomatic while at work, and was last on duty on Thursday 2 April 2020," a police statement said.
"She was tested after this date when advised of contact with a person - not the facility - who tested positive to COVID-19.
"No further police action is expected to be required."
The worker at Anglicare's Newmarch House aged care facility in Caddens went to work for six days with mild respiratory symptoms, particularly a sore throat.
She has since tested positive for the coronavirus. Five additional staff members and four residents at the facility have also tested positive.
"This person is absolutely mortified," NSW chief health officer Dr Kerry Chant told reporters on Wednesday.
"I would urge people to remember that the symptoms of COVID-19 can be incredibly mild and the key point is 'do not go to work'.
"I would particularly urge (that) if you work associated with providing care to the elderly, the aged and disability ... to have that incredibly high awareness of even minor changes in your health."
The health worker is "incredibly distraught" about the circumstances, Dr Chant said.
While Dr Chant said the woman "worked whilst she had very mild symptoms", Anglicare Sydney chief executive Grant Millard on Wednesday said she did not display any symptoms during her last shift at the facility.

"Nothing was disclosed to us when she was last seen on April 6th, she did not display any symptoms," Mr Millard told ABC TV.
The woman was seen by a residential manager at the time, he said.
"They displayed no symptoms, at that time they requested some time off work. We're not sure why they did that," Mr Millard said.
Anglicare on Sunday traced all workers in Newmarch House, including anyone who'd had contact with those infected at the home.
Some 40 staff at the facility have been stood down to self-isolate at home, Mr Millard said.
Approximately 100 residents - who have an average age of 85 - are isolating in their own rooms.
They are being tended to by staff wearing protective equipment.
"We brought in extra physios, extra staff in order to deal with this very challenging situation - it's very, very tough," Mr Millard said.
"People are rightfully upset. We're very concerned, but the critical issue at this stage is to ensure that we have the testing results for everyone in the home who has been tested yesterday."
Some family members of those in the aged care home are "very distressed by this", Mr Millard said.
NSW Police Commissioner Mick Fuller indicated before the inquiry, that officers would visit the home for the sake of transparency.
"The key question is, was there reckless intent? And my understanding is that there wasn't," Mr Fuller told reporters in Sydney.
"We'll ask those questions to management ... all the information I've been provided is that there was no malice at all."
If police thought there was reckless behaviour on the part of Anglicare then it would be reported, Mr Fuller said.
"That may not be criminal but may open up other agencies for oversight," he said.
The woman also worked two shifts at Greystanes Disability Services in Leura.
