It follows a 24-year-old student nurse testing positive for the virus after working at multiple hospitals across Sydney, including Royal North Shore.
More than 100 staff and patients at that hospital and Fairfield Hospital have been tested after coming into contact with the positive case.

"We envisage that once these centres are up and running that NSW Health will be able to administer up to 200,000 vaccines a week," she said.
"Once the supplies arrive, the challenge will be having all hands on deck.
"So we are doing our part."
A fourth new vaccination hub in the Hunter was announced earlier.
Another Virgin flight named as exposure site
Two passengers on a flight from the Gold Coast to Sydney have tested positive to coronavirus.
The passengers were on VA524 on Saturday June 26.
"We understand that both were isolating, but this is just still being confirmed from the second passenger," Chief Health Officer Kerry Chant said.
"This highlights the importance of us being able to find people very quickly, get them tested and then we can be confident if they are negative that they are not a risk to the community."
