Fig. 1

SARS-CoV-2 antibody levels by days since COVID-19 symptoms onset. IgA, IgG, and IgM levels are represented in log10 median fluorescence intensity (log10 MFI). Black dots represent seropositive individuals, and gray dots represent seronegative individuals. Paired samples are joined by gray lines (continuous lines in seropositive and dashed lines in seronegative). The blue solid line represents the fitted curve calculated using the linear model method. Shaded areas represent 95% confidence intervals
