Las Vegas Hotels Battle Legionnaires' Outbreaks

Health authorities in Las Vegas are investigating two separate outbreaks of Legionnaires' disease linked to the South Point Hotel and Casino and The Grandview. Both hotels have started remediation efforts following the discovery of Legionella bacteria in their water systems.

Legionnaires' disease, a type of pneumonia caused by inhaling contaminated mist, has affected guests at both hotels. Three visitors to The Grandview between February and April 2025 were hospitalized, while two individuals who stayed at South Point in 2024 and 2025 experienced severe respiratory illness but recovered. Environmental testing confirmed the presence of Legionella bacteria in the plumbing systems of both properties. Both hotels have initiated remediation efforts, including hyperchlorination and flushing of their plumbing systems. Guests who may have been exposed are encouraged to complete a confidential illness survey on the Health District's website. The Southern Nevada Water Authority (SNWA) and the Southern Nevada Health District (SNHD) oversee water supply and quality in Las Vegas hotels, ensuring compliance with regulations. Follow-up tests are planned for both hotels, and guests will receive notifications about the potential exposure.

The recent outbreaks of Legionnaires' disease in Las Vegas serve as a reminder of the importance of proper maintenance of water systems in hotels. While some diseases may be inevitable, Legionnaires' is preventable with adequate infrastructure upkeep. Both hotels are cooperating with authorities and have taken steps to address the issue, with follow-up tests and guest notifications planned.
