About the Study

In the study published in JAMA, researchers wanted to refine the criteria for MIS-C to differentiate between MIS-C and COVID-19 as part of an effort to improve health outcomes. The study, which included 539 patients with MIS-C and 577 patients with severe COVID-19 from 66 hospitals in 31 

U.S. states, found that patients with MIS-C were more likely than those with severe COVID-19 to be 6 to 12 years old, be non-Hispanic Black, and have severe cardiovascular or mucous membrane/skin involvement and more extreme inflammation. 

Patients with MIS-C had fever, inflammation, multisystem involvement and either positive reverse transcriptase-polymerase chain reaction (RT-PCR) test or antibody test results, or recent exposure to COVID-19 with no alternate diagnosis. Patients with COVID-19 had a positive RT-PCR test and severe organ system involvement.
