Ozger et al. (2021) demonstrated that at various stages of infection, elevated levels of IL-6, IL-7, IL-10, IL-15, IL-27, IP-10, MCP-1, and GCSF were predictive of mortality, with IL-6, IL-10, IL-7, and GCSF showing the highest sensitivity and specificity [38]. This evidence concerns the gene CCL2 and infection.
