Factors contributing to lower susceptibility of children to COVID-19

Abstract

The goal of this research to find out some factors that illustrates why children are less severe to COID-19 than adults. After doing this, we could say children have fewer of ACE2 receptor compared to adults. Also, the low level of TMPSS2 expression in children may protect them against severe form of COVID-19. Furthermore, the production of macrophages of inflammatory cytokines in children could protect them against the worst conditions.
