Figure 3. Endemic coronaviruses antibody levels and nasal
SARS-CoV-2 viral load. Levels of IgG and IgA to SARS-CoV-2 antigens in
nasal wash (left panels) and serum (right panels). a)Antibody levels in anosmic (blue) and normosmic (red) patients.b) Antibody levels in SARS-CoV-2 PCR negative (blue) and
positive (red) patients. c) Correlations between nasal
SARS-CoV-2 viral load (1/Ct) and antibody levels. The results are
expressed as median fluorescence intensity (MFI). *p<0.05, VL-
viral load, Ct -cycle threshold.
