Australian COVID-19 testing commander Jeroen Weimar said authorities were now concerned about examples of transmission with very little contact between cases. “They’re brushing past each other in a small shop, they’re going around a display home … they’re looking at phones in a Telstra shop,” he said. “They don’t know each other’s names, and that’s very different from where we’ve been before. “We think it’s primarily a feature of the [Delta] variant which is that it is just that much more contagious.”
