Acute Flaccid Myelitis

Acute flaccid myelitis (AFM) is a rare but serious condition. It affects the nervous system, specifically the area of spinal cord called gray matter, which causes the muscles and reflexes in the body to become weak.

Symptoms of AFM include:

  • Limb weakness
  • Loss of muscle tone and reflexes

Some individuals may also experience:

  • Facial droop/weakness
  • Difficulty moving the eyes
  • Drooping eyelids
  • Difficulty swallowing or slurred speech

If you or your child develops any of these symptoms, you should seek medical care right away.
