A Melbourne doctor has tested positive for coronavirus, becoming Victoria’s 11th confirmed case.

The man, aged in his 70s, recently travelled to America and became sick on his way home.

He is currently in home isolation, recovering from the illness, after being confirmed to have the virus on Friday night.

The Toorak Clinic, on Malvern Road, is closed until further notice.

The doctor saw about 70 patients in the last five days and also attended two patients at a nursing home in Malvern.

Those nursing home residents have been put into isolation in their rooms, as have other clinic staff and close contacts.

He returned to Melbourne from the US on the morning of February 29, having travelled to Denver and Vail, in Colorado, via Los Angeles.

He was there for 12 days before becoming ill.

“As such, he most likely acquired his infection in the United States,” a statement by the Victorian Department of Health and Human Services said.

The doctor had a runny nose on a flight from Denver to San Fransicoso, before flying back to Melbourne on United Airlines flight UA0060.

Authorities are working to inform all passengers who were on the same flight.

‘Absolutely flabbergasted’

Victorian Health Minister Jenny Mikakos slammed the doctor’s actions.

“Look I have to say that I am absolutely flabbergasted that a doctor who has experienced flu-like symptoms has presented to work,” Mikakos told reporters on Saturday.

“Our advice to the community generally has been if you have returned from overseas, and you are experiencing cold or flu-like symptoms then please stay home.”

Mikakos suggested the doctor may not have made the link to coronavirus because he had mild symptoms.

“It is irresponsible for people to be going to work if they are unwell and that’s not just healthcare workers, that’s everybody in the community,” she said.

The health minister added four screening clinics will be set up at Melbourne hospitals to take some pressure off emergency departments.

The clinics, opening on Saturday, are set up at the Royal Melbourne, The Alfred, Austin and Box Hill hospitals.

Those who suspect they might have coronavirus will still need to call ahead before presenting at the clinics.
