We hear daily that we are always behind the curve with the Covid-19 virus.At the present time we limit testing to those that are already ill and those that have a high chance of being exposed and having the virus. That means that the number of positives identified or always much lower than the number of actual infections. I have read reports that suggest there is probably somewhere between 10 to 24 times more infected than we are identifying. If we could randomly test the community we would be able to identify the amount of virus in the community much more accurately and get in front of the curve.

A). For people who don't show any symptoms, what kind of random sampling do you think would be desirable? And why?
