@amandalhu And here's a larger meta-analysis. Again, the definitions of "live" and "infectious" virus are a bit confusing and dependent on virus isolation in culture. https://t.co/UGxsyZoCq1 https://t.co/KkawDOp5u7

@SobsInEpi @libraryladykim It's possible, but check this out: 79 studies with 5,340 participants and no researcher was able to culture live virus past day 9. I know a lot of people who had positive antigen tests for weeks. Mine stayed positive for 21 day
@nelsonepega Copeland is wrong... "SARS-CoV-2 viral load in the upper respiratory tract appeared to peak in the first week of illness" . He said 2 - 3 weeks. https://t.co/Qu4stgTBkl
