This document discusses multisystem inflammatory syndrome in children (MIS-C), which has been associated with COVID-19. It describes the varying definitions of the syndrome from different health organizations. Common clinical manifestations include fever, gastrointestinal, cardiovascular, respiratory, and neurological involvement. Diagnostic testing often shows elevated inflammatory markers and cardiac enzymes. Imaging can reveal pneumonia or cardiac abnormalities. Treatment involves initial stabilization, antiviral therapy if COVID-19 is present, and immunomodulators for severe or refractory cases.
