Patterns of anti-SARS-CoV-2 S antibody response in patients with COVID-19. (A) IgG and IgM antibody response patterns in serum samples of all 32 patients with confirmed COVID-19; s, a significant difference by non-parametric repeated measures ANOVA; (B) IgG and IgM antibody response in a 65-year-old woman with severe COVID-19; (C) The difference in anti-SARS-CoV-2 IgG antibody response between severe cases and mild cases; (D) The difference in anti-SARS-CoV-2 IgM antibody response between severe cases and mild cases. (E) Numbers of blood samples collected during the study period. For statistical analyses, the Mann-Whitney U test was performed for continuous variables. Statistical testing could not be performed on days 22, 24, 25 and 27 due to the very small number of available samples. *p < 0.05 was considered statistically significant.
