Circulating concentrations of the markers of systemic Inflammation, CRP, TNF‐α, and IL‐6 (Figure 3) were substantially higher in the COVID‐19 group compared with age‐ and sex‐matched adults with co‐morbidities (CRP 13.0 mg/L, 95% CI: 7.3, 18.7 vs. 3.5 mg/L, 95% CI: 1.2, 5.7, p < 0.001; IL‐6 44.4 pg/mL, 95% CI: 10.5, 78.4 vs. 2.7 pg/mL, 95% CI: 1.9, 3.5, p < 0.001; and TNF‐α 2.5 pg/mL, 95% CI: 2.1, 3.0 vs. 1.2 pg/mL, 95% CI: 1.1, 1.3, p < 0.001). Here, CRP is linked to COVID-19.
