Background: The viral shedding time (VST) of SARS-CoV-2 mainly determines its
transmission and duration of infectiousness. However, it was heterogeneous in the existing …

The evolving nature of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)
has necessitated periodic revisions of COVID-19 patient treatment and discharge …

Since December 2019, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has
infected over four million people worldwide. There are multiple reports of prolonged viral …

Background Viral load kinetics and the duration of viral shedding are important determinants
for disease transmission. We aim i) to characterize viral load dynamics, duration of viral …

Objectives Our objective was to review the literature on the inferred duration of the infectious
period of COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS …

Prolonged viral shedding may pose a threat to the control of coronavirus disease‐2019
(COVID‐19), and data on the duration of severe acute respiratory syndrome coronavirus 2 …

Background Viral load kinetics and duration of viral shedding are important determinants for
disease transmission. We aimed to characterise viral load dynamics, duration of viral RNA …

Objectives To investigate factors associated with the duration of viral shedding in patients
with COVID-19, outside of Wuhan. Methods In this retrospective cohort study, patients with …

Background Long-term shedding of viral RNA in COVID-19 prevents timely discharge from
the hospital or de-escalation of infection prevention and control practices. Key questions are …

Objective To estimate the proportion of presymptomatic transmission of SARS-CoV-2
infection that can occur, and the timing of transmission relative to symptom onset …
