Meta Title

For Parents: Multisystem Inflammatory Syndrome in Children (MIS-C) Associated with COVID-19

Meta Description

Multisystem inflammatory syndrome in children (MIS-C) is a rare condition associated with SARS-CoV-2 (the virus that causes COVID-19), which usually occurs 2-6 weeks after a child is infected with SARS-CoV-2. The child’s SARS-CoV-2 infection may be very mild or have no symptoms at all and may go unrecognized. MIS-C causes different body parts to become inflamed, including the heart, lungs, kidneys, brain, skin, eyes, or gastrointestinal tract. MIS-C can be serious, even deadly, but most children who are diagnosed with this condition get better with medical care. CDC is still learning the underlying reasons why some children get MIS-C after SARS-CoV-2 infection and others do not. Most children who get MIS-C are previously healthy and do not have any underlying medical conditions. Of those children who do have an underlying condition, obesity is most common. CDC is working with state, local, and territorial health departments; U.S. and international scientists; healthcare providers; and other partners to continue to monitor and learn more about MIS-C.
