More recently, a novel severe acute respiratory syndrome-related coronavirus 2 (SARS-Cov2) has been identified as the etiological agent of COVID-19 (16), a respiratory pandemic disease that, in several patients, causes ARDS associated with high levels of pro-inflammatory cytokines (17) including Th17 cytokines such as IL-22, IL-17, and IL-6 (18, 19). This evidence concerns the gene IL22 and acute respiratory distress syndrome.
