Acute Flaccid Myelitis has been occurring in relatively high numbers every other year since 2014. This year the season is winding down, but ended up affected about 135 children, most (16) of them here in Texas. We don’t know what causes this polio like illness characterized by paralysis. It’s likely viral as affected children (average age 5) have had antecedent viral symptoms. Enteroviruses and coxsackie virus have been implicated. There is not much we can do about it for now other than to be aware and report cases when they become known.
