Vegas Luxor guest dies of Legionnaires

Published: Jan. 31, 2012 at 4:35 PM Legionella

LAS VEGAS, Jan. 31 (UPI) -- A guest who stayed at the Luxor Hotel and Casino in Las Vegas in December and contracted Legionnaires' disease has died, Nevada health officials said.

Brian Labus, a senior epidemiologist at the Southern Nevada Health District, said the Centers for Disease Control and Prevention has not released the patient's name or when he or she died, the Las Vegas Sun reported Tuesday.

Health officials found Luxor water samples tested positive for Legionlla bacteria.

Gordon Absher, vice president of public affairs for MGM Resorts International, said super-heating and super-chlorinating water was used to kill the bacteria in the area where the deceased guest stayed, within a day the test results were confirmed, Absher said.

Within 10 days the hotel will undertake a voluntary remediation for the rest of the hotel, Absher said.

"We take this very seriously," Absher told the Sun said. "Health of our guests and our employees is of paramount importance to MGM Resorts."

The Luxor also developed a monitoring plan to prevent this from occurring, Labus said.

Last spring, two guests staying at the Luxor also became ill with Legionnaires' disease, but both recovered.

At the time, the health district collected bulk water samples for an environmental assessment, but no Legionella bacteria were detected, officials said.

Outbreak of Legionnaires' Disease Traced to Hospital Fountain

HealthDay news image

WEDNESDAY, Jan. 11 (HealthDay News) -- A decorative fountain in a hospital lobby was the cause of a 2010 Legionnaires' disease outbreak in Wisconsin, a new study says.

Legionnaires' disease is a severe and potentially deadly form of pneumonia caused by the bacteria Legionella, which can be inhaled from contaminated water sources.

State and local health officials launched an investigation after eight people in southeast Wisconsin developed Legionnaires' disease. After interviewing the patients, investigators identified one hospital as the origin of the outbreak.

Environmental testing within the hospital found notable amounts of Legionella in samples collected from the "water wall" decorative fountain in the hospital's main lobby. All eight patients had spent time in the lobby, the study said.

The fountain was shut down when it was first suspected as a source of the outbreak and hospital officials alerted staff and about 4,000 potentially exposed patients and visitors. All eight patients recovered and no further cases of Legionnaires' disease occurred after the fountain was shut down.

Before the outbreak, the fountain had undergone routine cleaning and maintenance, the researchers said.

"Since our investigation, the Wisconsin Division of Public Health has developed interim guidelines advising health-care facilities with decorative fountains to establish strict maintenance procedures and conduct periodic bacteriologic monitoring for Legionella," study lead author Thomas Haupt, an epidemiologist with the Wisconsin Division of Public Health, said in a journal news release.

"The guidelines stress that until additional data are available that demonstrate effective maintenance procedures for eliminating the risk of Legionella transmission from indoor decorative water fountains in health-care settings, water fountains of any type should be considered at risk of becoming contaminated with Legionella bacteria," he added.

The study appears in the February issue of the journal Infection Control and Hospital Epidemiology.
