This special episode of That’s Pediatrics tackles a subject currently on the minds of pediatricians and parents alike: Acute flaccid myelitis (AFM). This is a rare childhood neurological disorder that causes weakness in the arms or legs — sometimes even paralysis. John Williams, MD, our division chief of Pediatric Infectious Disease at UPMC Children’s Hospital of Pittsburgh, talks about the recent outbreak of AFM with enterovirus virologist Carolyn Coyne, PhD, and Brian Martin, DMD, VP of Medical Affairs.
