Compared to controls with no known inflammatory condition, the median levels of eight chemokines/cytokines in the COVID-19 patients in our training cohort exhibit a roughly two-fold elevation over healthy controls: IL-6 (2.3), GROa (2.2), MIG (2.3), IP-10 (2.0), IL-15 (2.1), IL-12 p(70) (2.6), sCD40L (2.4) and IL-22 (2.0). The gene discussed is IL15; the disease is COVID-19.
