Multisystem Inflammatory Syndrome in Children (MIS-C) is a condition in which different body parts can become inflamed, including the heart, lungs, kidneys, brain, skin, eyes or gastrointestinal organs.

What causes MIS-C? 

The cause of MIS-C is not yet known. However, many children with MIS-C had the virus that causes COVID-19, or have been around someone with COVID-19, according for the Centers for Disease Control and Prevention. 

How serious is MIS-C?

MIS-C can be serious, even deadly, but most children who are diagnosed with this condition have gotten better with medical care.
