Risk monitoring dashboard

From Wednesday 30 August 2023, the NSW Health system transitioned from yellow alert to foundational level. 

The foundational level is the base level required to continue to protect patients, staff and visitors and underpins all the alert levels used during the COVID-19 pandemic. The foundational level includes existing infection prevention and control practices, and more information can be found in the FAQs on the Clinical Excellence Commission website.

The NSW IPAC Framework for Respiratory and COVID Safe Healthcare outlines the alert levels used to determine infection prevention and control measures for preventing and managing acute respiratory infections in hospitals and health facilities across NSW.

NSW Health continues to closely monitor and assess the way we respond to acute respiratory infections, including COVID-19, to keep patients, staff and visitors to our health facilities safe.
