Key Points Question Is Kawasaki disease (KD) associated with droplet- or contact-transmitted infection? Findings In this cross-sectional study of 17 235 pediatric patients, the number of admissions for KD showed no significant change (27.4% decrease) during quarantine owing to the COVID-19 pandemic, whereas there were significant decreases in numbers of hospital admissions for droplet-transmitted or contact-transmitted respiratory tract infections (75.3% decrease) and gastrointestinal infections (86.3% decrease). Thus, the ratio of KD admissions to admissions for these infections increased. Meaning These findings suggest that contact or droplet transmission is not a major route for KD development and that KD may be associated with airborne disease.
