Elevated levels for those factors are characteristic of a “cytokine storm (CS)”, which has been documented to occur in some COVID-19 patients, such as in a meta-analysis of 28 studies involving 346 COVID-19 patients, in which 60% of COVID-19 patients had elevated IL-6 and 51% IL-8 in cerebrospinal fluid [21]. This evidence concerns the gene CXCL8 and COVID-19.
