Overview

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.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.
The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:
  • High blood pressure.
  • Diabetes.
  • Heart failure.
  • Some types of heart valve disease.
Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:
  • Control high blood pressure, high cholesterol and diabetes.
  • Don't smoke or use tobacco.
  • Eat a diet that's low in salt and saturated fat.
  • Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
  • Get good sleep. Adults should aim for 7 to 9 hours daily.
  • Maintain a healthy weight.
  • Reduce and manage stress.
