More than 70 passengers on Qatar Airways flight QR898, which touched down in Brisbane on February 17 from Doha, were due to end their mandatory 14 days' quarantine yesterday, but will instead remain in two hotels until March 8. Three people on the flight have been diagnosed with SARS-CoV-2, the virus that causes COVID-19, while in Brisbane quarantine.
