Western Australia's Health Minister Roger Cook has urged people to protect their loved ones by staying away from aged care facilities if they are experiencing flu-like symptoms.

While there have been no new cases of coronavirus reported in WA since Thursday, authorities are expecting more cases to emerge.

Mr Cook said it was vital to protect the community's more vulnerable people.

"We know coronavirus patient outcomes for older and immune-compromised patients is much lower in relation to coronavirus, so it's important that people are aware of the impact they may have on older West Australians," he said.

"We love our parents and grandparents, but just stay away while you've got these flu-like symptoms.

"This is an important message because we know that people in residential aged care facilities are some of the most vulnerable.

"We've already seen some incidents in New South Wales and we want to make sure these people are protected."

No local virus transmissions

There have been three confirmed cases of coronavirus in Western Australia, including Diamond Princess cruise ship passenger James Kwan, 78, who died from the illness a week ago.

His 79-year-old wife also tested positive and remains in a stable condition in isolation at Sir Charles Gairdner Hospital.

And earlier this week, health authorities revealed a woman in her 30s tested positive to the virus after returning from a holiday in Europe.

There is currently no local transmission of the virus.

More than 1,100 West Australians have been tested for COVID–19 but returned negative results.

Call to treat patients remotely

Mr Cook is calling the Federal Government to help protect the state's GP workforce, by providing protective equipment, including face masks, to ensure that patients can continue to be treated at their local doctor's surgery.

He said the State Government had some protective equipment but needed "to make sure our hospitals, our COVID clinics and other areas of the health services in WA are ready to receive patients".

Mr Cook also wants video consultations with GPs to be covered by Medicare

"If we can treat patients remotely from their GP, we know that we can limit the spread of this infection, and doctors should be renumerated for treating those patients online," he said.

"We want this to be implemented as a priority because if we can treat patients without them having to go into a GP clinic, we know that we can limit the spread of the infection."

Mr Cook says treating patients remotely will help contain the virus.

Mr Cook was speaking at an Aegis nursing home in the Perth suburb of Como.

The company operates more than 25 aged care facilities across Perth, Mandurah and Busselton, and its staff look after 2,200 elderly residents.

Aegis nursing consultant Luci Rodda said they were as prepared as they could be and were concentrating on keeping the virus out of the facilities.

"We don't want to restrict and frighten people, but at the same time it is about our residents' protection and safety," she said.

Coronavirus testing clinics set to open

Three COVID-19 clinics will open in Perth on Tuesday, at Sir Charles Gairdner Hospital, Royal Perth Hospital and Fiona Stanley Hospital.

But Department of Health senior medical advisor Claire Huppatz said as there had been no local transmission in WA, the clinics were for people returning home from overseas.

"So if people have travelled overseas and get respiratory illness, so signs of fever, a cough, sore throat, any respiratory infection, they can go to those COVID clinics and get tested and seen by a health professional," she said.

"If we need to, we've got a plan in place to expand those clinics and expand their hours, and we're looking at new clinics elsewhere, should we need to."

The Health Department confirmed it is looking at hospitals in towns across the state as possible COVID-19 clinic locations as part of its pandemic planning.

"The idea of having those clinics beside hospitals is that people can come to those and should they need admission to hospital, they are right on the doorstop," Dr Huppatz said.

'There's no need to hoard': Minister

Mr Cook has urged West Australians not to panic.

"We have had no local transmission of this virus. The only three cases we have in Western Australia are those cases that were brought from overseas," he said.

"So there's no reason to panic, there's no reason you should not go to cafes, movies, go to your local shops, support local businesses.

"What's important right now is that people practice good personal hygiene, wash their hands.

"There's no need for people to do panic buying, there's no need for people to hoard."
