PAFAH1B2 and Herpesviridae infectious disease: When focusing on strict biomarkers in this analysis, we confirmed the same seven proteins for α-CoVs as in our prior study (33) and added eight (positive biomarkers: FCGR2B, PAFAH1B2, RNASE4, TSPAN2, and VNN3; negative biomarkers: AMY2A, LDHB, and LMNA) for herpesvirus infections and two (F5 and TCN2, both positive) for hemoplasma infections.
