In the current issue of EBioMedicine, Ng and colleagues attempt to address the above limitations of current serological assays by presenting a novel linear B cell immunodominant epitopes based assay for detecting exposure to SARS-CoV-2 [5] . Specifically, they identified a set of five immunodominant linear B cell epitopes from a peptide library of SARS-CoV-2 structural proteins by performing IgG reactivity test on pooled plasma samples of COVID-19 infected patients from Singapore. Consistent with multiple recent reports (e.g., [7, 8] ), the authors also found that the magnitude of IgG responses in COVID-19 patients against the identified epitopes correlated with disease severity. Second, the usefulness of serological assays in detecting prior exposure relies on the stimulation and persistence of SARS-CoV-2-specific antibody responses in infected patients. ./cache/cord-270886-m9na7cbm.txt ./txt/cord-270886-m9na7cbm.txt
