NSW Health's priority is to ensure the health and safety of our staff and patients.
NSW Health can advise that the case announced today is a healthcare worker who worked at Fairfield Hospital and Royal North Shore Hospital while infectious from the 24 June to 28 June.
The healthcare worker is now in isolation.
Patients in the affected wards and those who have been discharged from those wards are being notified and tested. Those wards are not admitting any new patients.
More than 100 staff and patients have been identified as close contacts to date, with investigations and contact tracing ongoing. Testing is in progress and to date, all have returned a negative result.
All steps to protect staff and patients have been taken to prevent any transmission.
NSW Health is contacting patients' families who may have visited these wards and identified close contacts of this case to advise them of any action they need to take.
The affected areas of both hospitals were cleaned and the hospitals remain open with services continuing to be provided safely.
Under the NSW Government restrictions introduced on Saturday 26 June for all hospitals, the public has been asked not to visit healthcare facilities at this time.
Visitors are restricted unless in exceptional circumstances.
