Concentrations and secretion rates of biomarkers of salivary immunity in athletes who had been infected with SARS-CoV-2 and those who had remained infection-free. No significant differences were found. Salivary IgA (SIgA), alpha-amylase (AMY), dash line (–) represents normal values reported in elite athletes. Concentrations and secretion rates for sIgA (n SARS-CoV-2 + = 14; n SARS-CoV-2- = 14) are presented as means ± S.D while alpha-amylase (n SARS-CoV-2 + = 13; n SARS-CoV-2- = 12) are presented as geometric means ± S.D.
