Additionally, key inflammatory markers of interest, C–C motif chemokine ligands 2, 19, and 20 (CCL2, CCL19, and CCL20), C–X–C motif chemokine ligands 8 and 10 (CXCL8 and CXCL10), and IL-10, were found in both nasopharyngeal swab material and the circulating blood of patients with COVID-19 across time points. This evidence concerns the gene CCL19 and COVID-19.
