Profile of RT-PCR for SARS-CoV-2: A Preliminary Study From 56 COVID-19 Patients

Abstract A novel coronavirus (COVID-19) pandemic threatens the world. Here, we first studied the dynamics profile of SARS-CoV-2 from 56 recovered patients with COVID-19. We found viral shedding occurred up to 6 weeks after onset of symptoms. A prolonged observation period is necessary for older patients.
