“The reality is if you’re over 70, you’re in a more vulnerable category, so that’s a risk factor, and people with chronic conditions, pre-existing illnesses, will be at greater risk as well,” Sutton told 3AW on Thursday.

Fifty-four new cases were also confirmed overnight, taking the state’s total number of cases to 520.

New measures

It comes a day after Premier Daniel Andrews warned he may implement further measures to fight the spread of the coronavirus, as the police union called for a state of disaster to be declared.

The state’s tally includes four health workers at Werribee Mercy Hospital in Melbourne’s outer west.

The hospital confirmed one emergency department worker tested positive to COVID-19 on Sunday.
