LAS VEGAS, Nev. (FOX5) - The Southern Nevada Health District is investigating Legionnaires' disease at two Las Vegas hotels.
SNHD said there have been confirmed cases at the South Point Hotel and The Grandview in the south valley.
According to a media release, the South Point Hotel & Casino had two travel-associated cases. One stayed in Aug. 2024 while the other visited in Feb. 2025. Both have since recovered.
At The Grandview, SNHD said there were three travel-associated cases this year. One person stayed in February while the other two were at the hotel in April. All three were hospitalized.
The health district said only one remains in the hospital as of the last update they received.
The Health District does not have additional information about the people involved, as they are not Nevada residents.
At the South Point and Grandview, the health district took a water sampling and it tested positive for Legionella. It's the bacteria that can cause Legionnaires' disease.
Both properties say it's conducting water system remediation efforts and is testing to ensure safety.
"The facility is fully cooperating with the Health District's investigation, and has initiated guest notifications regarding the potential exposure, and is implementing precautionary measures to mitigate any further risk of illness," the health district said.
For guests who stayed at the South Point on or after April 16, 2025 and who developed or are experiencing symptoms, are encouraged to fill out this survey.
Those who stayed at the Grandview on or after March 27, 2025 are encouraged to fill this survey if experiencing or have developed symptoms.
The health district said guests who stayed at The Grandview and South Point before May 7, and are not experiencing symptoms, are not considered at risk for infection.
"If guests are currently still symptomatic, they should seek medical attention and alert their medical provider of the potential exposure."
