You are correct. Testing is only part of the strategy. Social Distancing (stay at home) + testing + vaccine = strategy. However because we have no vaccine it has to be done in phases. as you know, data ala stats are only as good as to what they are intended or used for. Testing would have probably limited the outbreaks in nursing homes and senior facilities. Testing is also good because as we are now finding out, just because you have had the virus does not mean you can’t get it again. Finally, maybe the most important is that you may be a carrier without any symptoms so you wouldn’t even know you had the virus without a test. My sister in Florida believes her and her husband may have had it already. Who knows whether they infected someone else as they went on their daily lives.
