Good question… Over the weekend, 7 new cases were reported in Victoria, including 2 from the Arcare Maidstone nursing home, taking the outbreak total to 72 locally acquired cases. Officials have split the outbreak into 3 clusters – Whittlesea, Port Melbourne, and West Melbourne. And it’s the 10 cases in the last cluster that are worrying officials because they are associated with the Indian Delta variant that’s been found to be highly infectious – and the source has not yet been found. Yesterday, Deputy Chief Health Officer Professor Allen Cheng said about 5% of Victorians have been tested for COVID over the past week. “If there was a big outbreak going on, we would expect to have picked it up, but there’s always that risk,” he said. Melbourne’s lockdown is set to continue until Thursday night, and there’s some optimism that it will be lifted.
