These are not necessarily infections just positive tests. I have little faith in the accuracy of these tests as thy are often being administered under makeshift conditions like parking lots and processed in the thousands. What assurance do we have these tests can identify the new variants or even differentiate between them and the original strain? It strains credulity to believe these supposed new strains that appear almost daily in the media can be readily and accurately identified by a test of dubious accuracy for the original strain.
