SARS-CoV-2-specific IgG antibody levels were significantly higher in close contacts who were exposed in the hospital setting compared to the community (social exposure) ( P =0.017) ( Figure 3C ), while IgM antibody levels were close to significance ( P =0.05) ( Figure 3D ), SARS-CoV-2-specific IgG antibody levels were significantly higher in close contacts who were exposed through a colleague compared to a doctor–patient relationship ( P =0.042) ( Figure 2C ).
