"At the time of this report, of the 18 critically ill children requiring invasive ventilation, 2 have died, 3 still require mechanical ventilation, 7 have discontinued mechanical ventilation but remain hospitalized, and 6 have been discharged from the hospital.

The overall case fatality rate in this cross-sectional study was 4.2% up to the time of the report. The patients who died were aged 12 and 17 years; both had preexisting comorbidities and developed multisystem organ failure, and 1 had gram-negative sepsis prior to developing COVID-19.

Fifteen children (31%) were still hospitalized, including 5 in critical condition with 1 still receiving ECMO. For those patients with completed PICU and hospital admissions (they either died or were discharged), the median (interquartile range) PICU and hospital lengths of stay were 5 (3-9) days and 7 (4-13) days, respectively."
