This is what I was saying also a few weeks ago . It just takes one to be exposed and 90% of the time I am willing to bet they have been around other players, coaches, teachers , school friends . The UIL guidelines are so broad as to try and cover all possible liability for COVID that I think it just make an entire season almost impossible for any school. We are being told at work that even if you have been around some one who has tested positive that it might take the full 10 to 14 days before it could actually show in you and still you not have any signs or symptoms . With that it would seem that you would need to have the kids , and Coaches all tested at the end of the 14 day period or just prior to the end of the 14 day period.
