A systematic review notes that children with COVID-19 have milder effects and better prognoses than adults. [2] [3] However, children are susceptible to "multisystem inflammatory syndrome in children" (MIS-C), a rare but life-threatening systemic illness involving persistent fever and extreme inflammation following exposure to the SARS-CoV-2 ...
