Overview
- The Southern Nevada Health District, which announced the probe Tuesday, is investigating two travel-associated cases tied to stays at Wynn Las Vegas.
- Environmental sampling at the resort found Legionella in the water systems, and Wynn carried out immediate remediation with recent follow-up tests showing no detectable bacteria.
- One guest stayed in September 2025 and the other in February 2026, and both people have recovered.
- SNHD is notifying potentially exposed guests and urges anyone who stayed on or after Sept. 1, 2025 to complete a confidential illness survey and seek medical care if symptoms appear.
- Legionnaires’ disease is a severe pneumonia caught by breathing mist from contaminated water, not from other people, and recent alerts in North Carolina, Texas, and Baltimore show wider activity.
