A TOWNSVILLE woman has tested positive to coronavirus three days after she arrived in Victoria.
Queensland Health has today issued a public health alert in case the woman was carrying the virus before she left the state.
The woman, aged in her 30s, had attended numerous medical facilities in Townsville during the last week of September, before she flew to Cairns and then on to Brisbane.
From there she travelled to Melbourne to be with family while receiving medical care, and the COVID-19 tests were required as part of her medical treatment.
Queensland Chief Health Officer Dr Jeannette Young said while the woman may have contracted COVID-19 in Melbourne, it was necessary to treat the case with an abundance of caution.
"She was in Melbourne for three days before testing positive," Dr Young said.
"The likelihood is that she contracted COVID-19 there but as always we're acting with an abundance of caution."
Dr Young said urged Townsville residents to monitor their health and get tested if they experienced even mild symptoms.
"We have made incredible leaps and bounds in Queensland, and that isn't progress we take lightly," Dr Young said.
"Caution is key is ensuring we catch every possible case.
"That's why we are releasing the below locations as part of a Public Health Alert.
"We are asking anyone who has been to these suburbs at these dates and times to monitor their health.
"If you develop any COVID-19 symptoms, no matter how mild, get tested.
"The woman's treating doctors in Queensland have also taken COVID-19 tests and are isolating until they receive their results."
The woman had been in venues in Townsville, Cairns and Brisbane before travelling to Melbourne.
She was on flight QF2302, from Townsville to Cairns on October 3, and flew from Cairns to Brisbane on flight VA782 on October 6.
From there she travelled to Melbourne via Canberra, with Victorian health authorities responsible for contacting those on departing flights from Brisbane airport.
Dr Young said the Townsville locations the woman visited were the Icon Cancer Centre at Hyde Park, from 4pm to 5pm on September 28, Mater Day Surgery at Hyde Park on September 29 and October 1, and NQ Vascular at Pimlico between 1pm-2pm on September 30.
"Anyone who has been to these suburbs at these dates and times should monitor their health and if they develop any COVID-19 symptoms, even mild, get tested and isolate until they receive their test result," Dr Young said.
Dr Young said locations visited in Cairns and Brisbane were deemed to be very low risk, but further information would be provided if required.
