Swab test for COVID-19... "The polymerase chain reaction (PCR) swab test is useful (but not perfect) for detecting SARS-CoV-2 virus RNA in symptomatic patients.1 However, problems arise using the test for purposes that disregard symptoms or time of infection—namely, case finding, mass screening, and disease surveillance. This is because PCR is not a test of infectiousness. Rather, the test detects trace amounts of viral genome sequence, which may be either live transmissible virus or irrelevant RNA fragments from previous infection.2 When people with symptoms or who have been recently exposed receive a positive PCR result they will probably be infectious. But a positive result in someone without symptoms or known recent exposure may be from live or dead virus, and so does not determine whether the person is infectious and able to transmit the virus to others." ____________________________________ https://www.bmj.com/content/370/bmj.m3699 ____________________________________ https://www.bmj.com/content/370/bmj.m3558 ____________________________________ https://www.bmj.com/content/370/bmj.m3580 ____________________________________ https://www.bmj.com/content/370/bmj.m3585 ____________________________________ They told on themselves!!!
