This study aimed to characterize hemostatic parameters and associated clinical outcomes of COVID\u201019, such as thrombosis and bleeding, in children and to assess thromboprophylaxis use. This multicenter observational cohort study included 79 patients aged up to 18\u00a0years admitted to all pediatric hospitals in Qu\u00e9bec, Canada, with SARS\u2010CoV\u20102 infection during a 5\u2010month period. D\u2010dimers were elevated in 18\/19 patients (94.7%) and fibrinogen in 15\/26 patients (60%). Eleven patients (13.9%) received anticoagulant thromboprophylaxis.
