Thank you, Goosegg! I think that part of our problem is that the news cycle is now primed for many people to be watching continually (I do this myself), and thus they have to put out new items all the time, which mostly take the form of dire predictions one way or another. We've only been shut in for a month. In fact, data about all sorts of things will be coming out soon - testing, infection rates, treatments, etc. They now know that simply putting severe patients on their stomachs instead of on their backs is a major contributor to the survival of some people. I feel think/hope/feel the CDC must be putting all these things together, so that they can recommend treatments that are appropriate to people with various conditions.
I am hopeful that a combination of these new knowledges plus testing of the sort you describe will enable us to go back to semi-normal life, with more confidence, fairly soon. It will be useless to try to go back without that sort of confidence, though.
