Acute Flaccid Myelitis


Acute flaccid myelitis (AFM) is a rare syndrome that affects the nervous system, specifically the gray matter of the spinal cord. AFM is a serious condition and causes the muscles and reflexes in the body to become weak.  CDC continues to encourage healthcare providers to report suspect cases of AFM within 24 hours of suspicion to their local health departments. 

How to report a suspected case of AFM

Download the Job Aid for Clinicians guide with step-by-step instructions for reporting a suspected AFM patient.

Information should be sent on patients (of all ages) who meet the clinical criterion (sudden onset of flaccid limb weakness) regardless of any laboratory results or magnetic resonance imaging (MRI) findings. Learn more about the case definitions for AFM.
