Four children are currently battling coronavirus in Victorian hospitals, Health Minister Jenny Mikakos has confirmed.

Ms Mikakos stressed no one was safe when it came to the deadly virus with 20 per cent of patients currently in hospital aged under 50.

"This is not an older person's disease," she said.

Premier Daniel Andrews made an appeal to "younger people" to obey the rules, saying they too can suffer.

"We have to see compliance within the community at extraordinarily high levels," he said.

"I just want to try and, I fully acknowledge that this may not be the most targeted medium to be speaking to every young person. I'm not sure that there is one medium that would get us that outcome.

"But to people who are younger: If you want to get past these restrictions. If you want to get through this and see something that approaches normal ...

"If you want to protect yourself or someone that you love who has got an underlying condition ... even a moment's though on this the only thing to do is to get tested if you're sick.

"To isolate while you're waiting for a test and to follow the rules."

Mr Andrews said he was concerned press conferences were not the medium to communicate to this demographic and get the message across.

"I'm not singling younger people out for the purposes of blame. It is a significant part of our new cases and there is no getting around that," he said.

"There are a lot of young people who have died of this."

Ms Mikakos gave her condolences to the families of the five Victorians who lost their lives overnight.

"My thoughts and my sympathies are with those families and this demonstrates the growing toll this terrible virus is taking on our community."
