Notes from the Field : Powassan Virus Disease in an Infant — Connecticut, 2016

Abstract

In early November 2016, a previously healthy male infant aged 5 months from eastern Connecticut developed fever and vomiting. Right-sided facial twitching began over the next several days, and progressed to seizures that included rightward eye deviation and right arm stiffening. He was admitted to the hospital for evaluation and management of his seizures. There was no travel history; however, the parents reported that 2 weeks earlier, the infant had been bitten by a tick most likely carried into the home on a family member's clothing. The estimated time of tick attachment was <3 hours.
