Overall, only 22.7% of COVID-19 infected patients had detectable COVID-19 IgA antibodies with a mean of 27.3 ± 57.1 ng/ml, 29.6% had COVID-19 IgM antibodies with a mean of 188.4 ± 666.0 BAU/ml, while 59.2% had positive COVID-19 IgG antibodies with a mean of 101.7 ± 139.7 BAU/ml (Table 2) (S1 Table).
