Two recent guests at the Rio All-Suite Hotel and Casino contracted Legionnaires’ disease, a lung infection that causes pneumonia-like symptoms.
According to the Las Vegas Review Journal, the Southern Nevada Health District announced the confirmed cases Friday. One guest visited the hotel in March and the other visited in April.
After the cases of Legionnaires’ disease were confirmed, the Rio tested its water system and it tested postive for Legionella bacteria, which causes the disease. The hotel began using chlorine at high temperatures to disinfect rooms and water system on Thursday night, according to CNN.
The Rio disinfected again on Friday, and could disinfect on Saturday as well, according to the Review Journal.
According to the Center for Disease Control and Prevention, people contract Legionnaires’ disease when contaminated water spreads in small droplets that people can inhale. People can get Legionnaires’ disease through drinking water, but that water would have had to “go down the wrong pipe.”
Common symptoms of Legionnaires’ disease include coughing, shortness of breath, fever, muscle aches and headaches, according to the CDC.
According to the Southern Nevada Health District, guests who stayed at the Rio more than two weeks ago and have not developed symptoms are not at risk of contracting Legionnaires’ disease.
