ST. LOUIS COUNTY, Mo. — The Missouri Department of Health and Senior Services (DHSS) is warning the public about a possible health concern for anyone who stayed at the St. Louis Marriott West Hotel on or after Oct. 1.

DHSS found that two people, who were not associated with each other, were diagnosed with Legionnaires’ disease in October who also stayed at the St. Louis Marriott West during the same time period, according to a press release.

People can get Legionnaires’ disease by breathing in small water droplets containing Legionella germs, DHSS said.

DHSS is conducting an investigation and said they do not know if the hotel was the source of the germs that caused the two people to become sick.

Anyone who has developed symptoms within two weeks of staying at St. Louis Marriott West should seek medical attention right away. DHSS said if you experience symptoms, ask your doctor to give you a urine test and respiratory culture.

DHSS also said if you test positive, you should ask your doctor to report it to your local or state health department.

Symptoms of Legionnaires’ disease:

  • Cough
  • Shortness of breath
  • Fever
  • Muscle aches
  • Headaches
  • Confusion
  • Nausea
