Australia’s state of Victoria reported its biggest rise in local COVID-19 cases in nearly a week on Monday, as officials scramble to track its source.
Authorities reported 11 new cases, some of which were the highly infectious Delta variant, likely the cause of India's latest devastating outbreak.
Officials added all cases were linked to existing clusters.
Meanwhile, residents in the state’s capital city Melbourne wait for the latest lockdown to lift, scheduled for Thursday night.
But Victoria’s top health official, Brett Sutton, said plans could change.
"As I've always said we are looking at numbers everyday, we make those decisions on a day by day basis. I don't know what today will bring in terms of new notified cases.”
Melbourne on Monday entered its 11th day of a hard lockdown, after officials over the weekend found the Delta virus variant.
Australia has largely contained outbreaks with snap lockdowns, regional border restrictions and social distancing measures and nearly 20 percent of the country’s adult population has received a first dose of a vaccine.
