Multisystem inflammatory syndrome in children (MIS-C) is a condition that occurs in children under 21 years of age where different body parts can become inflamed, including the heart, lungs, kidneys, brain, skin, eyes, or gastrointestinal organs. MIS-C can occur at the end of a COVID-19 infection or later after the child has fully recovered. It can also occur after a COVID-19 infection that has no symptoms.
Common symptoms of MIS-C include fever, abdominal pain, vomiting, diarrhea, neck pain, rash, bloodshot eyes and feeling extra tired.
More serious symptoms include trouble breathing; pain or pressure in the chest that does not go away; new confusion; inability to wake or stay awake; pale, gray, or blue-colored skin, lips, or nail beds, depending on skin tone; and severe abdominal pain.
It is important to remember that:
- Not all children will have all the same symptoms.
- Recognizing the symptoms early and getting help are important for the best treatment and outcome.
- Contact your child’s doctor right away if they are showing symptoms of MIS-C.
- MIS-C can be serious, even deadly, but most children who are diagnosed with this condition will get better with medical care.
The best way you can protect your child is by taking everyday actions to prevent the virus that causes COVID-19:
- Vaccinating all eligible household members
- Frequent handwashing
- Social distancing
- Wearing a mask (for everyone over 2 years of age) when outside of your home
