The NFL, who I am guessing, is using the best testing money can buy just had a huge batch of false positives yesterday. The Bears had nine players test positive and every one was a false positive. How many of these local 'new cases' each day are due to faulty testing?
Testing has always been a red herring, if you have symptoms they will treat those symptoms wether you have Covid or some other ailment. In the rush to roll out testing we have a very inaccurate testing system and we are basing policy decisions on a system that we know it's flawed.
