I worked a very large healthcare system a while back, one of our support nurses came down sick, a home test was bought at Walgreens, positive result, employee sent home. CMO of that healthcare system asked us why did we bother testing, that they quit testing and just work through it. So there is that aspect to it also, how many just don't test at all?
Ironically my company requires vaccination or no jobby job, though they send a covid positive employee home half way across the country on a plane who was very sick, smh.
