But as I've written before, with labs running the tests through 40 cycles of amplification, how many of these tests are false positives, how many are notional positives that are not infectious, and how many are outright picking up coronavirus colds instead of SARS-CoV-2 — the very colds that have essentially protected children from contracting significant symptoms of COVID-19?
Five of them contained samples of non-infectious SARS-CoV-2-positive cells, two contained samples of coronavirus colds (HCoV-NL63, HCoV-OC43), and one was completely negative.
A 2.9% false positive rate among HCoV-OC43 samples and a 3.1% false positive rate among HCoV-NL63 samples.
Now consider the fact that young children get coronavirus colds (which account for 15%-30% of common colds) more often, which is why some researchers believe they have more robust cross-immunity from memory T cells, at least against the serious disease that could result from contracting SARS-CoV-2.
Which means that the mass COVID testing of asymptomatic children could likely even pick up asymptomatic coronavirus colds, which function like pain-free vaccines for children against COVID-19.
