What do we know about Kawasaki disease and COVID-19?

In addition to the existing concern generated during the current COVID-19 pandemic outbreak in the adult population, we see how this pathology affects the pediatric population in the same way. Several countries have declared health alerts for a new syndrome that occurs late in children exposed to COVID-19, called "multisystem inflammatory syndrome". These patients manifest symptoms similar to Kawasaki disease, but at rare ages, and it is considered as the cytokine storm manifestation in children. The objective of this review is to present the available information on COVID-19 and its relationship with Kawasaki's disease, as well as to explain the current hypothesis of this new syndrome, its physiopathology, clinical presentation, key differences with Kawasaki's disease, and its possible therapeutic interventions.
