My assumption has been that the primary purpose of testing is for contact tracing. I would suspect that probably don’t have enough tests at this point to usefully test everybody who is ill and yet still planning to go to work, even just people with healthcare jobs—I’m assuming that someone who is ill, but still thinking about going to work at their healthcare job, is probably not very sick, in which case most of those tests would end up negatives, on people who just have colds/flu.
