Then, we analyzed IL-1β, IL-6, IL-8, and IL-10 levels in nonsurvivor and survivor COVID-19 patients, and our results suggested that the levels of IL-1β, IL-6, and IL-8 levels were elevated in nonsurvivor patients compared to survivor patients, which indicated that IL-1β, IL-6, and IL-8 might be related to COVID-19 patients' prognosis. Here, IL6 is linked to COVID-19.
