Acute flaccid myelitis (AFM) is a rare but serious neurological illness that causes muscle weakness, sometimes leading to paralysis. Early detection and collection of specimens can help identify cases and causes of AFM. Below is a collection of information and resources on acute flaccid myelitis, including a PediaLink Education Course.
Brief Overview
Acute flaccid myelitis (AFM) is a rare but serious neurological illness that causes muscle weakness, sometimes leading to paralysis. Early detection and collection of specimens can help identify cases and causes of AFM. Below is a collection of information and resources on AFM.
Increases in cases of AFM have occurred between August and November in the United States in 2014, 2016, and 2018. These spikes in cases have been attributed to enterovirus outbreaks, particularly EV-D68. The biennial pattern was interrupted in 2020, likely due to the nonpharmaceutical interventions implemented to prevent the spread of COVID-19. It is unclear when or if spikes in AFM cases will occur again.
Early detection and medical support are critical to improve long-term health outcomes of children with AFM. Delays in recognition can put children at risk. Pediatricians and pediatric health care providers who can identify AFM and promptly hospitalize patients are best positioned to provide optimal medical care.
