KCL researchers are suggesting

that somewhere between 0.46 million and 6.6 million have been infected. It's really impossible to know whether what we have is just a winter bug or CV. We are not particularly ill, but none of us are shaking it off as we normally would. As we live in Central London we were almost certainly exposed at some point.
If the higher figure is accurate, an antibody test would, as Boris suggests, be a game changer, allowing those of our DC who got over it without realising they were ill, get on with their lives. And also give us a better sense of how dangerous it is, and hence an understanding of the risks of otherwise healthy people resuming normal activity.
Whatever, DD is using it as an excuse for normal student behaviour (not getting out of bed, and snapchat) and I am following her example.
