SARS-CoV-2 RNAemia and clinical outcomes in children with COVID-19.

The burden of COVID-19 in children represents a fraction of cases worldwide, yet a subset of those infected are at risk for severe disease. We measured plasma SARS-CoV-2 RNA in a cohort of 103 children hospitalized with COVID-19 with diverse clinical manifestations. SARS-CoV-2 RNAemia was detected in 27 (26%) of these children, lasted for a median of 6 [2-9] days, and it was associated with higher rates of oxygen administration, admission to the intensive care unit, and longer hospitalization.
