“…Recessive or dominant inborn errors of IFN immunity can underlie the COVID disease in unvaccinated adults. Inborn errors of IFN immunity also are seen in children ( 119 , 120 ). Pre-activated antiviral innate immunity has been described in children as a factor in upper airways that controls early SARS-CoV-2 infection, with a higher basal expression of the viral RNA sensors MDA5 and RIG-I in cells from children than from adults ( 119 ).…”

“…Recently, a multisystem inflammatory syndrome in children, also known as MIS-C, has been identified as a rare but fatal complication of otherwise mild severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children and young adults [ 41 ]. It is characterized by a hyperinflammatory state that closely mimics KD.…”

“…It is characterized by a hyperinflammatory state that closely mimics KD. Unlike KD, which usually affects children below five years of age, MIS-C affects slightly older children aged between 7 to 12 years of age and has a more severe disease course with features of hemophagocytic lymphohistiocytosis (HLH) leading to multiorgan dysfunction syndrome (MODS), cytopenia, shock, and myocarditis [ 41 , 42 , 43 ]. Cytokine storm underlies the hyperinflammatory state.…”

“…The majority of cases reported correspond to males, with a proportion of 1.5 to 1 (male/female), as previously reported in the general population [ 18 , 19 ]. A higher prevalence of MIS-C in males has been reported in the Mexican population; although the reason is not clear, it could be due to a higher risk of developing COVID-19, and it has been hypothesized that specific immune defects could predispose males to MIS-C [ 20 , 21 ].…”
