Four healthcare workers in the emergency department of the Werribee Mercy Hospital have now tested positive for COVID-19.
One staff member tested positive on Sunday and the 3 other staff members considered to be at risk were also tested and found to be positive.
Health Minister Jenny Mikakos speaking at a media conference on Wednesday said that they would be contacting all of the patients that may have been exposed to the virus through the staff members.
The emergency department is still open to the public and has since been thoroughly scrubbed using strict protocols in line with cleaning and infection control.
