Impact of Social Distancing on Kawasaki Disease-associated Hospitalization, South Korea

Abstract

We conducted a cohort study to estimate the impact of social distancing on incidence of Kawasaki disease (KD) in Korean children, using the nationally representative data. The KD-related hospitalization rate has declined significantly from -38.8% (April) to 81.7% (June). The decrease in diagnosis of KD adds clue for infectious etiology of KD and the establishment of preventive measures.
