The cases come after a person tested positive at the Mildura Law Courts on Tuesday, October 5.
The ABC understands the person was tested after presenting to the court with COVID-like symptoms.
On Sunday, a Merbein resident tested positive to COVID and has since been receiving at-home hospital care.
