Timeline of IgG (dotted line)/IgA (dashed line)/IgM (solid line) antibody levels against N (square)/S1 (triangle)/RBD (circle) antigens of SARS‐CoV‐2 and NAb (diamond) against SARS‐CoV‐2 after symptom onset in P1 (A), P2 (B), P3 (C), P4 (D) and P5 (E). Thick lines show the cut‐off value (10 AU/ml) indicating a positive result for all kits. (F) Schematic representation of the SARS‐CoV‐2 Spike protein domain. AU, arbitrary units; N, nucleoprotein; NAb, neutralizing antibody; RBD, receptor‐binding domain; S1, spike 1 subunit; S2, spike 2 subunit; SARS‐CoV‐2, severe acute respiratory syndrome coronavirus 2
