It doesn't necessarily mean absolutely no cases in the community or no new cases, but it does mean that we'd be looking to make sure that they don't have unlinked community transmission, which is what they're dealing with at the moment. They're getting cases popping up where they don't know how that person got it. Once they get back to a point where it's more predictable, which, through contact tracing, it is possible to get to that point—once you get down to a low number of cases, it's possible that new cases pop up, but you knew who they were, they were in isolation already, and therefore the risk is low. We'd certainly be wanting to get to at least that point before we'd consider opening up again.
