Multisystem inflammatory syndrome (MIS-C) is a rare, but serious post-COVID condition that primarily affects school aged children. It can cause parts of the body to become inflamed, including the heart, lungs, kidneys, brain, skin, eyes, or stomach, after being sick with COVID-19.

More information about MIS-C can be found at the Wisconsin Department of Health Services webpage: Multisystem Inflammatory Syndrome in Children (MIS-C).
