Fast facts about AFM:

AFM is a rare but serious condition that affects mostly children and generally causes sudden muscle weakness.

Symptoms include sudden weakness in the arms or legs. Some people also experience drooping of the eyelids or face, difficulty moving eyes, slurred speech or difficulty swallowing.

If parents see potential symptoms of AFM in their child, they should contact their health care provider promptly.

Experts are working to determine the exact cause of AFM.

There is no specific treatment for AFM or proven prevention strategy, but washing hands, covering your cough and staying home if you’re sick can help avoid illness.
