The revelation comes as a State public health expert said as much as 30 per cent of the WA population could become infected with the virus over the course of its spread.
The Joondalup employee was one of the three health care workers identified by Minister for Health Roger Cook yesterday as contracting the virus.
Another of the workers has been revealed to be working at the Aegis Ascot aged care facility in Bayswater which has gone into a lock-down.
The third health care worker has not yet been identified.
Mr Cook said WA’s cases of the virus have increased to 31 overnight while a further 6582 tests have been returned negative.
“In relation to those people we have a male in his 30s who has travelled from the UK, a male in his 50s who has travelled from Thailand and male in his 20s who has travelled from Ireland via Dubai,” he said.
Mr Cook gave few details about the health workers who had tested positive to the virus and said he would not do so until contact had been made with people who had interacted with them.
“The department is now contract tracing any patients or staff members that they came in contact with and once all close contacts have been notified the Department of Health will release details to the extent we can whilst maintaining patient privacy,” he said.
“They worked across three different areas of health but not in general practice, I can also confirm they were not public sector workers.
“At this stage we can say there is still no community based transmission of the virus in Western Australia and that’s a very good position for us to be in.”
Communicable Disease Control Directorate director Paul Armstrong said he expected there would be community transmission of the virus in the “next couple of weeks”.
He said the Department of Health had a broad range estimated for how many people in WA would be infected with the virus as the pandemic ran its course.
“It depends on how effective our social distancing measures are, we would expect by the end of this and this is going to last several months … that perhaps 20 to 30 or even higher per cent of the population will be infected,” he said.
“We just don’t know that yet. It depends on how well our public health measures are put in place to slow the spread down.
“It will reach a point where it burns out and all epidemics do that, that’s not to say the COVID virus won’t be around next year, the year after and the year after that.
“In this first big wave the estimates are not precise but that’s the sort of ballpark we’re looking at.”
The frequency of positive cases is increasing with 13 positive tests returned in just a 24 hour period.
