Rare syndrome linked to COVID-19 found in nearly 600 U.S. children: CDC
Multisystem inflammatory syndrome (MIS-C) is a rare but severe condition that shares symptoms with toxic shock and Kawasaki disease, including fever, rashes, swollen glands and, in severe cases, heart inflammation. It has been reported in children and adolescent patients about two to four weeks after the onset of COVID-19. With rising COVID-19 cases, there could be an increased occurrence of MIS-C, but this might not be apparent immediately because of the delay in development of symptoms, said the report's authors, including those from the CDC's COVID-19 response team.
