Longer Duration of SARS-CoV-2 Infection in a Case of Mild COVID-19 With Weak Production of the Specific IgM and IgG Antibodies.

The relationship between SARS-CoV-2-carrying time and specific antibody production has not yet been reported in re-admitted COVID-19 patients. We reported a case of mild COVID-19 with long virus-carrying time, weak production of virus-specific IgG and IgM antibodies, and recurrence of positive SARS-CoV-2 RNA in stool specimens after discharge. A 27-year-old male was diagnosed as COVID-19 after returning to Meizhou from Wuhan.
