MORE WORRIED ABOUT MELBOURNE THAN SYDNEY Prof Collignon said until those links could all be pinned down, there was a possibility the Victoria outbreak may have come from somewhere other than NSW. "In some ways, I'm a little more concerned by the cases in Melbourne than Sydney," he said. "That it's from NSW is a presumption at the moment and that's why we need genomic testing given there's been restrictions in NSW for quite a while, as well as between Sydney and Victoria and that the virus is not that widespread among people in Sydney." He added, "It's a worry none of these women have been to Sydney in the last two to three weeks. If it isn't related to Sydney then how did it get here?"
