Description:In August 2018, CDC noted an increased number of reports of patients having symptoms clinically compatible with acute flaccid myelitis (AFM), a rare condition characterized by rapid onset of flaccid weakness in one or more limbs and spinal cord gray matter lesions, compared with August 2017. Since 2014, CDC has conducted Surveillance for AFM using a standardized case definition (1,2). An Epi-X* notice was issued on August 23, 2018, to increase clinician awareness and provide guidance for case reporting.
Patients who meet the clinical case criteria for AFM, defined as acute flaccid limb weakness, are classified using the Council of State and Territorial Epidemiologists case definitions of “confirmed” (magnetic resonance imaging [MRI] with spinal cord lesion largely restricted to gray matter and spanning ≥1 spinal segments), “probable” (cerebrospinal fluid [CSF] pleocytosis [>5 white blood cells per mm3]), or “not a case.”
