Long-Term Persistence of Anti-SARS-COV-2 IgG Antibodies.

ABSTRACT: Antibodies against severe acute respiratory syndrome coronavirus-2 (Anti-SARS-COV-2) can be detected in patients with COVID-19 in 7 to 10 days post onset of symptoms (POS). However, there is no firm evidence of the long-term persistence of these antibodies in recovered COVID-19 patients. Therefore, this study aimed to evaluate the stability of anti-SARS-COV-2 IgG in recovered COVID-19 patients in a 15-month follow-up testing. Thirty hospitalized patients with real-time PCR-confirmed SARS-COV-2 infections were included in the study and five serum samples (1st, 2nd, 3rd, 4th, and 5th) were collected from each participant. The serum levels of N and S specific anti-SARS-COV-2 IgG and IgM antibodies were evaluated by the immunoassay technique at the same time. To determine the correlation betwe
