RESUMEN
The etiology of Kawasaki disease (KD) and its precise genetic basics remain unknown. Genetic variants affecting immunity have been found in some patients. The occurrence of KD in siblings is rare, but KD pedigrees with multiple affected members have been described in Japan and North America. Cases in twins have been documented. We report 2 pairs of trizygotic triplets who developed KD associated with SARS-CoV2 infection from 2 different families. Our cases show that KD is multifactorial in origin, and both infectious etiology (particularly SARS-CoV2 as in our cases) and genetic factors are relevant in the disease.

Multisystem inflammatory syndrome in children is a new entity in association with SARS-CoV2. Clinical features of Kawasaki disease were noted from the first reported cases of MIS-C. Before the COVID-19 pandemic, Kawasaki disease shock syndrome was considered to be a distinct and unique form of KD. We present a representative case that prove the current difficulty in clearly distinguishing MIS-C from pre-COVID-19-KDSS and emphasie the overlap of the diagnostic criteria.
