Fecal viral shedding in COVID-19 patients persisted for 49 days
Fecal viral shedding in COVID-19 patients: Clinical significance, viral load dynamics and survival analysis.
In particular, positive fecal signals persisted for 49 days in patient "I" after symptom onset and for 33 days in patient "G" after viral tests in oropharyngeal swabs became negative.
Survival analysis showed no significant difference in the duration of positive signals for SARS-CoV-2 RNA in respiratory samples between patients with negative and positive fecal viral tests. The median survival of positive viral signals was significantly longer in fecal samples than that in oropharyngeal swabs.
Note: Above is also why oral swab tests are not as accurate. Follow @LidCovid on Twitter for more information regarding toilet plume.
