Assessment of cytokine levels among patients with acute COVID-19 and individuals in the post-COVID-19 period showed significantly higher levels of IL-17 (p=0.0002; Figure 1A), TNF-α (p<0.0001; Figure 1C) and IL-2 (p<0.0001; Figure 1G) in the post-COVID-19 group and higher levels of IL-6 (p<0.0001; Figure 1E) in the acute COVID-19 group. Here, TNF is linked to COVID-19.
