SMH reports:
Woman with UK strain of virus travelled from Victoria to Queensland
A woman who tested positive to the UK strain of COVID-19 travelled from Victoria to Queensland earlier this month.
The woman first tested positive to the strain while in Victorian hotel quarantine, completed her isolation period, cleared her symptoms and was allowed to travel to Queensland.
But she again returned a positive COVID-19 test yesterday when she was tested by Queensland health officials, the state's chief health officer Dr Jeannette Young said.
"That's why we are now following through with her contacts. The risk is extremely low, very, very, very low because she is right at the end of her potential infectious period, and with a normal variant, we would not be at all concerned," Dr Young said.
"But it is not zero risk, so we are just taking all of those precautions."
The woman arrived in Victoria on December 26 after flying in from the UK. She was returned a positive test in hotel quarantine on December 27, and then completed 10 days of isolation. She was allowed to leave Victoria and fly to Queensland on January 5, arriving in Brisbane on a Jetstar flight.
"Then she travelled up to Maleny [on the Sunshine Coast] where her parents live and she has been staying with her parents. Her parents have been tested and we're working through any close contacts that need to be looked at there," Dr Young said.
Dr Young said it was uncertain whether the woman was infectious on the flight. "I don't know. She would have been ... at the end of her infectious period, but she did test positive yesterday."
Some people continue to excrete the virus for 120 days after their illness is complete, so exit testing is not typically a requirement for COVID-19 patients to exit isolation.
"You've got to have had first no symptoms for three days, and then second, at least 10 days since you tested [positive]. So she met those two criteria, so therefore she was allowed to leave isolation," Dr Young said.
She said exit testing had now been re-introduced as a requirement for people with the UK mutant variant.
