Severe COVID-19 disease is associated with a so-called “Cytokine Storm” [9,10,11], which is a dramatic increase in inflammatory cytokines/chemokines (especially IL-1β, IL-6, IL-8, and TNF-α) and other inflammatory factors that promote tissue injury and can predict the severity of COVID-19 and survival [9]. Here, CXCL8 is linked to COVID-19.
