People in the Australian city of Sydney have been ordered to remain at home for one week, as authorities scramble to contain an evolving outbreak of the Delta Covid-19 variant.
Sixty-five cases of the virus have been detected so far in this outbreak.
The outbreak is directly linked to a limousine driver who became infected two weeks ago when he transported a flight crew from the airport to a quarantine hotel.
Authorities have been concerned with instances where people have been passing on the virus in fleeting encounters in shops and other communal areas.
Premier Gladys Berejiklian today ordered anyone who resides in four central Sydney neighbourhoods to remain at home, unless for essential purposes.
A ban on Sydney residents from leaving the city has also been extended until next Friday.
Australia has been very successful in its battle against Covid-19, but this battle is becoming increasingly challenging in recent months as more transmissible variants of the virus emerge.
