Figure 3. Possible immune response in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-COV-2 RNA and antigen are shown with dark blue; specific immunoglobulin (Ig)M, with light blue; specific IgG, with red; and specific IgA, with green. The figure depicts a peak in IgM followed by increasing IgG and IgA levels. The SARS-COV-2 RNA starts to decline after a peak in specific IgM and IgG levels. Low levels of antibodies may persist even after the convalescent phase [10].
