Las Vegas: Legionnaires’ disease investigations at The Grandview and the South Point Hotel
Officials at the Southern Nevada Health District report investigating travel associated Legionnaires’ disease cases who stayed at Las Vegas hotels.
Two cases of Legionnaires’ disease in individuals who stayed at the South Point Hotel are being investigated. One person stayed at the property in August 2024, while the other stayed in February 2025. Both individuals have since recovered.
Following notification of cases, the Health District conducted environmental water sampling at the facility. Multiple water samples tested positive for Legionella, the bacteria that can cause Legionnaires’ disease. In response, the South Point Hotel is conducting immediate water system remediation efforts and conducting follow-up testing to help ensure the safety of its water systems. 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.
In addition, three cases of Legionnaires’ disease in individuals who stayed at The Grandview are being investigated. One person stayed at the property in February 2025, while the other two stayed in April 2025. All three were hospitalized; two have since recovered, and one remained hospitalized at the time the Health District received the report.

Legionnaires’ disease symptoms typically begin within two to 10 days after exposure to the bacteria. However, people should watch for symptoms such as cough, shortness of breath, fever, muscle aches and headaches for up to two weeks after exposure. Guests who stayed at the hotels before May 7, 2025, and are not experiencing symptoms, are not considered at risk for infection.
