Wynn Resorts Guests Affected by Legionnaires’ Disease – Two Cases Confirmed

Two Legionnaires’ disease cases have been recorded and tied to visits and stays at the Wynn Las Vegas, according to the Southern Nevada Health District, which has urged anyone who may have stayed at the property on or after September 1, 2025, specifically to conduct an anonymous health survey, helping the inspectors get a better understanding of the incidences of the disease.

Cases Detected Quickly, Property Responds Decisively 

The cases are several months apart, but the SNHD has urged screening all the same. One of the cases was recorded in September 2025, and the other in February 2026, with both patients recovering, and the property embarking on a swift, immediate, and comprehensive remediation of its water system.

The disease is water-borne and caused by the Legionella bacteria, which were already detected in multiple water samples taken from the property. However, the freshest samples collected by the SNHD were not able to detect any traces of the bacteria whatsoever. 

According to the SNHD, the completion of the health survey is especially helpful to health authorities. 

Information from the Public Critical to Health Authorities 

“Completing this survey is critical to the investigation and helps public health officials quickly identify any additional cases and ensure appropriate follow-up. Those who are currently experiencing symptoms should seek medical attention and inform their primary care provider of the potential exposure,” a statement by the SNHD read. 

The health survey can be particularly helpful even if people experienced only mild symptoms or were able to recover quickly. 

While treatable, Legionnaires’ disease is highly contagious and in some cases fatal. In February, the estate of Gary Curtis Jones filed a lawsuit in which it alleged that the South Point Hotel Casino and The Grandview were negligent in protecting guests from the disease. 

Another lawsuit, also linked to a guest’s death, was filed against Harbor Island Apartments, later rebranded as The Harmon at 370, and Coast Hotels and Casinos, which operates The Orleans Hotel and Casino, last March.
