But does anyone really know if they really had covid, or just a regular flu variant, or possibly even a cold? Since the covid test are widely known to produce false positives, just based on the test results alone would seem to be pretty inconclusive. Since the test is known to be unreliable, is the "antibody test" also just as unreliable? I believe that it is possible the actual, real, covid virus, IS pretty deadly, but after the initial wave of it in some places, the numbers are now highly diluted by the false positive tests.
