On the negative side, one of the concerns has to be that the social network is increased—that is, we've found another person with another social network—more specifically, what appears to be the brother—and it's not clear that he was picked up in the first sweep and, therefore, all his contacts also widen, and so our net is wider today. I think, secondly, if we imagine that the first grouping was a family—mother, father, daughter—and now we have a completely different grouping—that is, we understand the relationships within the family, those close contacts, but now it's jumped across a classroom, purportedly, to another family. That's a worry. We've now jumped out of the family and across the classroom. So I think we need to take that into account for what it is. I am reassured by what we're being told, that 75 percent of cases have come back as negative. I think that's a good thing, but, of course, that's a negative in terms of, if we're fishing where the fish are, and that's what we're looking for—you know, are we testing in the right place? So, again, just want to offer some sense of hope with today's news.
