Based on the previous report of Mahallawia and collaborators (2018) (44), in which it was shown that patients with acute MERS-CoV infection presented both Th1 and Th17 responses, our findings show a significant positive correlation between IL-12p70, a classical Th1 cytokine, and IL-17 in the COVID-19 groups. The gene discussed is IL17A; the disease is COVID-19.
