Of those, 11 people were "completely in isolation", five people were "partially in isolation", and two people "infectious in the community".
A third staff member has also tested positive to Covid-19 at the SummitCare aged care home at Baulkham Hills in Sydney's north west.
Five residents at the centre also previously tested positive to the virus.
The operator has confirmed the new infection and it says the affected staff member had been in isolation, as they worked closely with the other two infected staff.
