Yes, Tony, totally agree. I think they just needed to come up with a metric. The percent positive test measures two things… first, how many people are feeling sick or nervous and think they might have COVID and second, what percentage of those people actually do have COVID. Mildly interesting, but not useful. A better approach would be a randomized testing strategy across the whole population. I think the percent positive of that group would be well under 2%.

You don’t know anything about the folks being tested are they asymptomatic or have no symptoms? Also how many more folks either have had the virus and never been tested?
