Multisystem inflammatory syndrome in children (MIS-C) is a rare condition that affects children who had COVID-19. It causes inflammation in several parts of your child’s body, including their:
- Heart.
- Lungs.
- Kidneys.
- Brain.
- Skin.
- Eyes.
- Organs within your child’s digestive tract (gastrointestinal).
It’s usually accompanied by a fever that lasts longer than 24 hours.
MIS-C can be very serious and life-threatening in rare cases. If your child shows symptoms, like difficulty breathing or severe chest pain, visit the emergency room immediately.
How common is multisystem inflammatory syndrome in children?
MIS-C is rare. It affects an estimated 1 out of every 3,000 to 4,000 children who had the COVID-19 virus.
What is the difference between MIS-C and MIS-A?
Both MIS-C and MIS-A refer to the same condition. The difference is the age of the person diagnosed. MIS-C affects children and young adults younger than 21 years old. MIS-A affects adults above age 21. MIS-C is more common than MIS-A, but MIS-A has more severe cases.
