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

Ai Tang Xiao et al. Clin Infect Dis. .

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.

Keywords: COVID-19; SARS-CoV-2; dynamics profile.

Dynamic profile of RT-PCR for SARS-CoV-2. A, Dynamic profile of SARS-CoV-2 detected by RT-PCR from 56 patients with COVID-19 (n = 299). Numbers of the positive (red bars) and negative (blue bars) results of SARS-CoV-2 RT-PCR tests were summed on weeks after the onset of symptoms. B, Positive rate of SARS-CoV-2 detected by RT-PCR from 56 patients with COVID-19 (n = 299). Percentages of positive results of SARS-CoV-2 RT-PCR test were calculated on weeks after the onset of symptoms. Abbreviations: COVID-19, coronavirus disease 2019; RT-PCR, reverse transcription–polymerase chain reaction; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.
