A 6-Year-Old Boy with COVID-19-Positive Pleural Effusion and Kawasaki-Like Features.

The ongoing outbreak of the novel coronavirus (SARS-CoV-2) has exposed many pediatric patients from around the world to coronavirus disease. Although pleural effusions are classified as atypical features of COVID-19 infection, we report a 6-year-old boy who had a positive IgG antibody ELISA test for COVID-19 and presented with respiratory distress, bilateral pleural effusions, and signs and symptoms of multisystem inflammatory syndrome. The RT-PCR test of the pleural fluid specimen was positive for novel coronavirus. To our knowledge, this is the first pediatric report of a COVID-19-positive pleural fluid.
