Authorities in Colorado are currently investigating a potential outbreak of Legionnaires’ disease linked to the prestigious Ritz-Carlton hotel, Bachelor Gulch, situated in the resort town of Avon. On February 27, the Eagle County Public Health and Environment (ECPHE) department, in conjunction with the Colorado Department of Public Health and Environment (CDPHE), revealed that they were examining three reported cases of the disease that are believed to have connections to the hotel.

The individuals experiencing symptoms of Legionnaires’ disease reported their conditions between July and December 2025. Fortunately, no fatalities have been reported as a result of this outbreak. In response to the findings, the Ritz-Carlton hotel has temporarily shut down all hot tubs and spa facilities following the detection of Legionella bacteria during routine water testing.
The ECPHE confirmed the measures taken in a press release, stating that the affected facilities have recently reopened after thorough remediation efforts and subsequent testing, which confirmed that the systems are now free from Legionella. Furthermore, the hotel has communicated alerts to both guests and staff regarding the situation to ensure comprehensive awareness.
Health officials have reassured the public that there is currently no risk posed to the wider community. ECPHE is collaborating closely with the CDPHE and the management of the Ritz-Carlton hotel to eliminate any remaining risks and to safeguard the health of both guests and employees.
Legionnaires’ disease, caused by the bacteria Legionella, manifests as a severe type of pneumonia. According to the Centers for Disease Control and Prevention (CDC), individuals can contract the disease by inhaling aerosolised water containing the bacteria, which can originate from sources such as hot tubs, showerheads, or decorative fountains. Importantly, it is not transmissible from one person to another.
While the majority of healthy individuals exposed to Legionella do not exhibit symptoms, certain populations, including smokers, individuals over 50, and those with underlying health conditions such as cancer or chronic lung disease, are at a heightened risk. Immediate medical attention and antibiotics can effectively treat the disease once it has been diagnosed. Symptoms typically include coughing, fever, headaches, and muscle aches, usually developing within two to fourteen days post-exposure.
Heath Harmon, the director of ECPHE, emphasised the importance of community collaboration in public health efforts. In a statement, he expressed the necessity for strong partnerships to protect community health, stating, “While our teams are often working behind the scenes to fight for clean water and stop the spread of disease, we cannot do it alone.” He acknowledged the quick response made possible by cooperation between public health departments and the hotel’s management.
To date, the Ritz-Carlton, Bachelor Gulch has not addressed multiple requests for comment from various media outlets regarding this incident. The ongoing investigation highlights the vigilance required in ensuring public safety, particularly in locations frequented by visitors.
The situation serves as a reminder of the importance of monitoring water systems in public venues, especially those involving shared facilities like hot tubs and spas. Authorities advise that ongoing inspections are necessary to prevent future occurrences of similar outbreaks.
As the investigation continues, health officials are working diligently to inform and protect the community, while ensuring that the management of the Ritz-Carlton hotel implements the necessary safety measures. More updates are expected as new information emerges regarding this concerning outbreak.
