Multisystem Inflammatory Syndrome

Abstract

The novel coronavirus (severe acute respiratory syndrome coronavirus-2), also referred to as coronavirus disease 2019, has caused a global pandemic that cost more than 900,000 deaths and affected nearly 80 million Americans since the start of the pandemic in early 2020. A majority of cases have primarily been reported in the adult population. Initially, lower morbidity and mortality rates were noted in children, compared with adults. However, some pediatric patients have been shown to develop a rare, but severe complication of severe acute respiratory syndrome coronavirus-2 infection, referred to as Multisystem Inflammatory Syndrome in Children. The condition has now been reported in adults as well. In this article, the origins, clinical features, pathogenesis, treatment, and latest literature on multisystem inflammatory syndrome are explored.
