Victoria’s Chief Health Officer Dr Brett Sutton released a statement confirming the fourth case after she tested positive for the deadly virus on Friday afternoon.

“After spending time in Wuhan, Hubei Province, she returned home to Victoria on January 25 and became unwell two days later,” he said.

“The woman is not considered to have been infectious on her flight to Melbourne.

“Since then, she has remained at home and isolated and has had no visitors.

“There are therefore no public exposure sites and the department has not identified any close contacts that require follow up,” he explained.

Dr Sutton also said advice to the public and health services and general practitioners has not changed.
