Inflammatory syndromes associated with SARS-CoV-2 infection: dysregulation of the immune response across the age spectrum.

Available evidence suggests significant heterogeneity in the human immune response to SARS-CoV-2. In this Viewpoint, we examine the spectrum of SARS-CoV-2-associated clinical inflammatory syndromes identified in adult and pediatric populations to date. A better understanding of the immunopathologies and related clinical manifestations of these syndromes is necessary to improve their diagnosis and management.
