Abstract. Antibodies to SARS-CoV-2 coronavirus were detected in 2338 patients by enzymelinked immunosorbent assay of immunoglobulins of the IgM and IgG class. Among 2997 studies, the detection of antibodies to immunoglobulin class IgM was performed in 549 (18.3%), to IgG immunoglobulin - in 1122 (37.4), and in the remaining 1326 (44.2%) patients studied the presence of antibodies to both immunoglobulins. The incidence and titer of binding antibodies to IgG immunoglobulin correlated with the manifestation of clinical manifestations (severe and asymptomatic - 74.4% and 25.6%, respectively) in patients with COVID-19.
