Vacation-Rental Hot Tub Linked to Legionnaires’ Disease in New York

New York public health investigators used whole-genome sequencing to link two Legionnaires’ disease cases to a private-use hot tub at a vacation rental; environmental testing and WGS showed the hot tub as the likely source, leading to a public nuisance order requiring professional remediation; after mandatory cleaning and two follow-up tests showing no viable Legionella, the hot tub was approved for reopening, underscoring the need for better hot-tub maintenance in short-term rentals and traveler awareness.
