Abstract: Anti-S/N IgG/IgM levels, blood group A + , cardiovascular and tumour disease, NSP12 Q444H and ORF3a S177I were independent predictors of clinical characteristics with anti-S/N IgM being associated with the need for hospitalization (multivariate regression, P < 0.05, respectively).
Result: The blood group A + was identified as an independent predictor for bronchial secretions and cough whereas the latter demonstrated the SNV ORF3a S177I as an additional independent predictor (P < 0.05, respectively).
Table: S177I
Discussion: While the occurrence of bronchial secretions was only associated with blood type A, the absence of the non-sy
