IL6 and COVID-19: In this study, IL-6 was found to be significantly more in symptomatic as compared to asymptomatic patients. Chen et al. reported a similar finding with significant elevation in the level of inflammatory cytokine IL‐6 in critically ill COVID‐19 patients [2]. Similarly, Liu et al. showed that a higher serum level of IL-6 was an independent and reliable risk factor for COVID-19 patients and led to higher disease severity and mortality [19]. IL‐6 is an important pro‐inflammatory factor in the disease process of SARS‐CoV‐2.
