Figure 8. Salivary IgM was associated with the absence of most symptoms.

Figure 8

A. The relationship between symptom presence (weakness, muscle ache, nausea, loss of taste and smell and upper respiratory symptoms [including cough, shortness of breath, sore throat, nasal obstruction (stuffy nose), nasal discharge [runny nose]) and semi-quantitative SARS-CoV-2 N-antigen and anti-spike antibody levels in saliva and TW of symptomatic infected individuals was assessed at baseline as determined by LFA. The Mann-Whitney U test detected a relationship between the absence of symptoms and higher oral IgM levels in saliva. B. Longitudinal oral virologic characterization of symptomatic participants detects viral persistence with concurrent antibody responses suggesting presentation post-acute infection. Saliva (triangle) and TW (circle) were assayed by LFA for detection of N-antigen (red), anti –spike IgG (green) and anti-spike IgM (blue) at entry, 14d and 28d (n=12).
