The total number of confirmed cases of COVID-19 in Queensland has risen to 13 after two more were announced.
An 81-year-old man who returned from Thailand and a 29-year-old woman who travelled from London with a stopover in Singapore were the 12th and 13th cases.
The man is currently in the Sunshine Coast University Hospital in a stable condition while the woman is isolated in Brisbane.
This has renewed calls from the state government for those who feel unwell after returning from overseas to visit a doctor.
Three other people are being treated for the coronavirus across the state, including a 26-year-old Logan man who returned home from Iran.
The state government says in a statement it is trying to contact all the people who were on his flight and were sitting within two rows of him.
Fifteen staff members from the emergency department of Brisbane’s Mater Hospital are in self-quarantine for 14 days after they were exposed to a Chinese student who contracted COVID-19.
The hospital said it was a precautionary measure in keeping with advice from Queensland Health.
On Thursday morning, the housemate of the Chinese student was released from hospital after testing negative.
He is now at home and has been advised to self-quarantine.
Eight other patients who contracted the virus have been cleared.
