On Monday afternoon, Professor Brett Sutton said he believed the child who tested positive was part of a swimming class at the Jump! Swimming School on May 21.
He said health authorities did not yet know how many close contacts were at the premises when the positive case attended the centre.
Victorian Health Minister Martin Foley said there were no changes to current COVID-19 restrictions but the coming days would be telling.
“We are not ruling in or out further measures .. . the evidence will determine our response,” he said.
