The Southern Nevada Health District has announced an investigation into two cases of Legionnaires' disease at Caesars Palace Hotel and Casino in Las Vegas. The cases are believed to be travel-associated, with both individuals developing symptoms shortly after their stays at the renowned establishment.

According to the health district, one person stayed at Caesars Palace in December 2023, while the other visited in June 2024. Legionnaires' disease is a severe form of pneumonia caused by the Legionella bacteria, as stated by the Centers for Disease Control and Prevention (CDC).

Following the first reported case, extensive water sampling was conducted throughout the property. Fortunately, all the samples tested negative for Legionella. However, upon learning of the second case, specific water sampling was performed in July from Caesars Palace's Palace Tower. Out of the 19 initial samples taken from various points in the water system, one sample tested positive for Legionella, while all the others came back negative.

Prompt remediation procedures were carried out by the facility in response to the positive sample, and subsequent tests have shown negative results. Caesars Palace Hotel and Casino has been fully cooperative with the ongoing investigation and has taken steps to notify its guests about the situation.

The health district has provided important information for individuals who may have been exposed to Legionella bacteria. They state that symptoms of Legionnaires' disease typically manifest within two to 10 days after exposure. Common indicators include cough, shortness of breath, fever, muscle aches, and headaches, which can persist for up to two weeks. However, guests who stayed at Caesars Palace before July 11, 2024, and have not experienced any symptoms are deemed to be at no risk for the disease.

For those who believe they may be experiencing symptoms related to Legionnaires' disease, the health district has made a survey available to gather necessary information and provide guidance.

As the investigation unfolds, the Southern Nevada Health District continues to work diligently to ensure the safety and well-being of all visitors to Caesars Palace Hotel and Casino in Las Vegas.
