Southern Tick-Associated Rash Illness in Pediatric Patient, New York, USA, 2025.

Southern tick-associated rash illness (STARI) is a tickborne disease of unknown etiology characterized by an erythema migrans-like skin lesion. We report a STARI case in New York in a child after an Amblyomma americanum tick bite; we detected Borrelia lonestari, a disputed cause of STARI, in the tick.
