A woman in her 60s has been diagnosed and is believed to have contracted the virus from her husband, who returned recently from Iran, health authorities said.

The couple are self-isolating at home, with regular monitoring being conducted by the Health Department.

The woman's husband is being tested for the virus and efforts are also underway to track who else the man may have come into contact with since returning to WA.

He has been in WA for 13 days and authorities said they were speaking with him through a translator to try to track his and his wife's movements.

Another man, in his 40s, was on Monday confirmed as the state's sixth case. He is believed to have contracted the virus from his mother, who flew in to WA from Jakarta.

She stayed in WA for six days before flying on to Melbourne.

WA Health Minister Roger Cook said it was the first confirmed human-to-human transmission of the potentially deadly coronavirus in WA and was identified after health authorities tested all family members who came into contact with the woman.

Health authorities are tracking the movements of all six cases in the state.

COVID clinics open from Tuesday

The Health Department confirmed three "fever clinics" would open at Royal Perth, Fiona Stanley and Sir Charles Gairdner hospitals from Tuesday to deal with patients presenting with suspected symptoms of COVID-19.

The clinics would be able to test up to 200 people a day, but would screen patients to prioritise testing for those who met specific criteria regarding symptoms, recent travel history and contact with confirmed cases.

The department expected many people attending the clinics would be told they could go home without testing and security experienced with crowd control would be on hand to deal with any difficulties.

Patients will be initially assessed and asked to fill in a survey in a waiting area outside the COVID-19 fever clinics. ( ABC News: James Carmody )

Conducting of the tests would be a quick process that involved taking swabs from the mouth and nose.

Shade structures have been erected outside the clinics, chairs set up and portable toilets made available for those waiting.

Signage would instruct people to keep a distance of 1.5 metres from one another at the clinics, while staff would be equipped with protective clothing and some desks protected with glass screens.

The clinics would be open from 8:00am-8:00pm and it was expected they would also be established in the state's regional centres in coming weeks.

Russell Brand cancels concert

It comes after the state confirmed its fourth case of coronavirus on Sunday in a woman in her 70s, who returned from overseas on Thursday.

She had been in Cuba and spent six days in London before returning to Perth.

After developing symptoms on Friday morning, she was tested and returned a positive result late on Saturday night.

In the meantime she visited several public places, including a West Australian Symphony Orchestra performance at the Perth Concert Hall on Saturday evening.

Efforts are underway to contact anyone who sat near her at the event and on her flight into Perth.

British comedian Russell Brand was supposed to perform at the same venue tonight, but on Monday issued a tweet that the show would be cancelled.

In a message to his fans, Brand said he was "not happy with the risk for me or for any of you" following the virus scare.

In a statement posted to Facebook, Perth Concert Hall management said, contrary to Brand's concerns, the venue was safe.

"Rest assured that Perth Concert Hall is open for business as usual," the statement said.

"The venue has been fully cleaned in line with Government guidelines and all performances are proceeding as scheduled."

School travel bans extended to US, Canada

The increasing spread of the virus has prompted the WA Government to extend a school travel ban to include travel to the United States and Canada.

Education Minister Sue Ellery said the extension of the ban to both staff and students applied to all public, private and Catholic schools, and came following the increased spread of COVID-19 across the US.

New Zealand is now the only country where school travel has not been suspended.

Mr Cook said it was only a matter of time before coronavirus became more widely spread in the WA community.

"It's a question of when, not if," he said.

"Look at the situation in New South Wales and that's Western Australia in three to four weeks from now.

"You will continue to see the prevalence of this virus, and you will start to see community-based transmission. As that happens we will need to ramp up our response."

So far 46 people in NSW have tested positive to COVID-19.

Only one person has died from coronavirus in WA — 78-year-old James Kwan, who contracted the disease after being evacuated from the Diamond Princess cruise ship in Japan.

Mr Kwan's 79-year-old wife, who was also infected, has now recovered from COVID-19 and has been discharged from Sir Charles Gairdner Hospital to rest at home.
