Public health physician Kathryn Taylor called on younger generations to follow advice about social distancing to protect their older loved ones.
"I understand our way of life is changing, the little things we used to do without thinking aren't possible anymore, but as a public health doctor and young mum I can tell you this virus does not care about disrupting our way of life,' she said.
"In fact, we fuel the virus by maintaining our normal social activities."
Dr Taylor said this virus does kill people and pleaded with the community to social distancing.
