Accordingly, higher levels of the chemokines CXCL8 (46.9 pg/ml [0.72 to 100.34] vs 15.3 pg/ml [0 to 39.8], p = 0.018) and CCL2 (590.4 pg/ml [33.8 to 1,116.8] vs 105.6 pg/ml [3.23 to 588.5]) were detected in MIS-C than in COVID-19 (p = 0.0086) (Figures 3D, G). This evidence concerns the gene CXCL8 and COVID-19.
