Publishing MIS-C surveillance has provided awareness of the condition and severe COVID outcomes for the public and providers. This surveillance will continue; however, this page will no longer be updated after 5/11/2023. Providers can access MIS-C resources here MIS-C Children (michigan.gov).
What is MIS-C?
“Multisystem Inflammatory Syndrome in Children (MIS-C) is a delayed hyperinflammatory condition in children and adolescents that occurs 2-6 weeks after SARS-CoV-2 infection. Children with MIS-C typically present with fever and various other symptoms, including abdominal (gut) pain, bloodshot eyes, diarrhea, dizziness, skin rash or vomiting. Not all children have the same symptoms. MIS-C can be serious, but most children who are diagnosed get better with medical care.
Health care providers and local health departments are asked to maintain a high degree of suspicion for MIS-C in pediatric and adolescent patients presenting with symptoms similar to Kawasaki Disease or ill individuals who have been previously exposed to COVID-19 with signs and symptoms. Patients have presented with fever, shock, multiorgan (cardiac, gastrointestinal, hematologic and dermatologic) involvement, and elevated inflammatory markers.”
