*Classification of AFM cases is determined by the Centers for Disease Control and Prevention (CDC).  In 2014, the case definition for AFM was as follows: onset of acute limb weakness on or after August 1, 2014 and a magnetic resonance image (MRI) showing a spinal cord lesion largely restricted to gray matter in a patient ≤21 years of age. Since 2015, AFM cases have been classified according to the Council of State and Territorial Epidemiologists’ (CSTE) standardized case definition for AFM.

**Confirmed cases in 2018 as of January 17, 2019.
