Health Officials Probe Two Las Vegas Hotels Following Legionnaires’ Disease Cases

Health authorities are investigating two separate outbreaks of Legionnaires’ disease linked to the South Point Hotel and Casino and The Grandview in Las Vegas, bringing into question water safety protocols at some of the city’s most popular venues. While the bacteria causing the disease rarely affect healthy individuals, there has been at least one reported fatality in recent months.

The Properties Are Swiftly Remedying the Situation

Data from the Southern Nevada Health District confirmed that two individuals who stayed at South Point in August 2024 and February 2025 manifested a severe respiratory illness. Fortunately, they fully recovered. As for The Grandview, three guests visiting between February and April 2025 had to be hospitalized. Environmental testing uncovered the presence of Legionella bacteria in the two hotels’ water systems.

Both properties have started remediation efforts, including hyperchlorination and flushing of their plumbing systems. A Health District statement noted that the two hotels would face follow-up tests while guests would receive notifications. Both properties are fully collaborating with the investigation and taking all the necessary measures to ensure their guests’ safety.

The facility is fully cooperating with the Health District’s investigation, has initiated guest notifications regarding the potential exposure, and is implementing precautionary measures to mitigate any further risk of illness.

Southern Nevada Health District statement

These incidents follow growing scrutiny of water safety in Las Vegas as rising Legionnaires’ cases have prompted lawsuits and public concern. In March, the Orleans Hotel and Casino faced legal action after relatives of one of its guests alleged that contaminated water systems led to a fatal case of Legionnaires’ disease that claimed the life of a 67-year-old woman.

Guests Facing Symptoms Can File an Anonymous Report

Legionnaires’ disease is a kind of pneumonia caused by inhaling mist contaminated with Legionella bacteria. Typical sources include cooling towers, hot tubs, ornamental fountains, and plumbing systems, especially in large installations like hotels, hospitals, and office buildings. While most healthy individuals do not manifest any symptoms, smokers, the elderly, and people with weakened immune systems face higher risks.

Symptoms typically start within two to ten days of exposure and consist of cough, fever, shortness of breath, muscle aches, and headaches. The Health District encourages individuals who visited the two properties and manifest any of these symptoms to complete a confidential illness survey available on the authority’s website. Medical providers treating patients who recently visited the properties must also be wary of Legionnaires’.

As Las Vegas continues attracting millions of visitors annually, some diseases will inevitably spread. However, Legionnaires’ is avoidable as long as hospitality and residential facilities remain aware of the potential dangers and take extra care to maintain their infrastructure and water systems. Unfortunately, negligence can damage a property’s reputation and even cost human lives.
