Acute Flaccid Myelitis Associated With Enterovirus D68: A Review

Abstract

Acute flaccid myelitis is a disease that affects the anterior horn cells of the spinal cord, leading to rapid onset of flaccid paralysis. Recent biennial epidemics, beginning in the summer of 2014, have been associated with enterovirus D68, although the underlying pathophysiology is unknown. Patients present with asymmetric flaccid weakness of the extremities, with cranial neuropathy and without encephalopathy, and often have residual disability. Here we review the current literature on this disabling disease and discuss treatment modalities and ongoing research.
