Health Minister Brad Hazzard has implored people not to go to work if they are sick, after an unwell Sydney aged care worker kept working before she tested positive to COVID-19.
Mr Hazzard says the worker at Anglicare's Newmarch House aged care facility in Caddens, in western Sydney, went to work while she had symptoms of illness for six days.
She has since tested positive for the coronavirus, as has a resident of the facility.
Another resident is still awaiting test results, Anglicare Sydney said in a statement on Monday.
Mr Hazzard said the message to everyone was that they shouldn't go to work when unwell.
"If you're feeling sick, and you're working in an aged care facility, you're working with some of the most vulnerable people in our state. Please don't go to work," he told reporters on Monday.
"Unfortunately, the potential is disastrous consequences."
Newmarch House staff who were in close contact with the resident or their colleague are self-isolating at home while all residents are in self-isolation in their own rooms.
The woman also worked two shifts at Greystanes Disability Services in Leura, with all residents now isolating in their own rooms and six staff in self-isolation at home.
NSW had recorded nine new cases of coronavirus on Monday, taking the total confirmed cases to 2863.
The state recorded two more COVID-19 deaths, taking the NSW COVID-19 death toll to 26.
A 74-year-old woman died in John Hunter Hospital and a 79-year-old man died in the Northern Beaches Hospital.
Both were passengers on the Ruby Princess cruise ship, which is linked to hundreds of COVID-19 cases nationwide.
