“The estimated time until loss of virus RNA detection ranged from 45.6 days for nasopharyngeal swab samples to 46.3 days for feces samples in mild cases and from 48.9 days for nasopharyngeal swab samples to 49.4 days for feces samples in severe cases”

Further evidence that #SARSCoV2 viral RNA can be detected for several weeks out in many types of samples, but this likely does not correlate w/ transmission potential or infection.

Have seen this clinically so many times- people have already had #covid19 and gotten better, & yet weeks later when they are presenting for something completely different, docs are checking #SARSCoV2 PCR again! And then scratching head when it’s positive...
