Abstract

The ongoing pandemic of coronavirus disease 2019 poses a great threat to human beings. Although numerous patients have recovered, re-positive cases have been reported in several countries. Till now, we still know very little about the disease and its pathogen severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Therefore, more attention should be paid to the following aspects, such as post-discharge surveillance, asymptomatic infection, re-evaluation of influenza-like symptoms, and dynamic monitoring of genomic mutation of SARS-CoV-2.

Keywords: Asymptomatic infection; COVID-19; Follow-up; Re-positive; SARS-CoV-2.
