Figure Lengend Snippet: Prevalence of IgG specific for betacoronavirus RBDs in study cohort. Plasma was assayed by ELISA using recombinant, multimeric RBD as antigen. (a) SARS-COV-2 spike 319-591 with p values from ANOVA with Tukey HSD for all pairwise comparisons shown beneath. (b) SARS-CoV spike 384-655 with p values shown as above, (c) MERS spike 306-577. Each point indicates an individual participant. Blue bars show median values. N = 7–30. (d) Comparison of absorbance values for MERS and SARS-CoV RBD binding IgG for all participants. Each point indicates an individual participant, n = 124. The orange circle indicates participants with detectable amounts of MERS RBD-binding IgG, showing correlation with SARS-CoV-binding IgG in this subset. IgG specific to recombinant, multimeric RBD from seasonal betacoronaviruses, (e) OC43 spike 315-675, (f) HKU1 spike 307-675 assayed by ELISA as above.

Figure Lengend Snippet: Comparison between peptide seropositivity frequencies in the primary dataset with an independent cohort. Peptides that showed >20 percentage point difference in frequency of seropositivity between participants in the Chelsea survey who had been hospitalized and those who reported exposure to SARS-CoV-2 are shown in green. The differences in frequency of seropositivity for IgG specific to those peptides between acutely hospitalized patients and people with no history of infection are shown in blue.
