Acute Flaccid Myelitis (AFM) Information from the CDC for Parents and Health Care Professionals

Acute flaccid myelitis (AFM) is a rare condition. It affects a person’s nervous system, specifically the spinal cord, causing weakness in one or more limbs. AFM or neurologic conditions like it have a variety of causes such as viruses, environmental toxins, and genetic disorders.

Since August 2014, CDC has seen an increased number of people across the United States with AFM. We have not confirmed the cause for the majority of these cases. CDC has been actively investigating these AFM cases, and we continue to receive information about suspected AFM cases. The CDC is urging health care providers to be vigilant for AFM among their patients and to send information about suspected cases to their health departments. School nurses should be familiar with symptoms which would prompt referral to parents. Click here to learn more.
