Abstract
Background
The viral shedding duration of SARS-CoV-2 has not been fully defined. Consecutive detection of SARS-CoV-2 RNA from respiratory tract specimens is essential for determining duration of virus shedding and providing evidence to optimize the clinical management of COVID-19.
Research Question
What are the shedding durations of SARS-CoV-2 RNA in upper and lower respiratory tract specimens respectively? What are their associated risk factors?
