Health authorities in Adelaide, South Australia have ordered 4,000 people into quarantine as the Australian state fights a new coronavirus outbreak.
South Australia reported five new coronavirus cases on Tuesday, bringing the total number of the latest cluster to 21. More than 6,000 tests were conducted Tuesday, according to the state's Premier Steven Marshall.
The cases are all considered to be linked to a worker in a medi-hotel, where international arrivals into Adelaide are required to quarantine for 14 days.
The cluster broke South Australia's seven-month run without local transmission.
There are currently 34 active cases in the state, including imported cases.
