ABSTRACT
ABSTRACT Background:
This study aimed to evaluate IgG and IgM levels in COVID-19 recurrence.Methods:
The serum antibody levels and clinical data from 73 healthcare workers with SARS-CoV-2 divided into seroconverted (n=51) and non-seroconverted (n=22) groups were assessed. The presence of specific anti-nucleocapsid (anti-N) IgM and IgG for SARS-CoV-2 was evaluated. IgG antibodies to the SARS-CoV-2 spike receptor-binding domain were used to confirm non-seroconversion in all negative anti-N.Results:
Four recurrent cases displayed mild symptoms and were non-seroconverted until the recurrence of symptoms.Conclusions:
Undetectable anti-nucleocapsid IgM and IgG levels may be correlated with symptomatic COVID-19 recurrence.
