Background
Case isolation and contacts tracing are the most widely used strategies to control the outbreak of COVID-19. However, little attention has been paid to the infectiousness of recovered patients with COVID-19.
Case presentation
In this study, we reported a confirmed case of COVID-19 whose nasopharyngeal swab test of SARS-CoV-2 RNA turned positive 28 days after hospital discharged.
Conclusions
SARS-CoV-2 RNA can be detected in respiratory tract sample 28 days after hospital discharged. Further studies about consecutive detection of SARS-CoV-2 combined with viral isolation among COVID-19 cases should be designed to determine the accurate contagious period.
