The Bacterial Culprit
Legionnaires’ disease is a severe form of pneumonia caused by Legionella bacteria. These bacteria thrive in warm, stagnant water, making hot tubs an ideal breeding ground. When people inhale water droplets containing the bacteria, they can become infected.
Recent Outbreaks
- Cruise Ship A: Between November 2022 and April 2024, eight cases of Legionnaires’ disease were reported on a single cruise ship.
- Cruise Ship B: Four more cases were identified on another cruise ship between January and June 2024.
- In both instances, the CDC’s investigation pointed to the hot tubs as the likely source of infection. Six infected patients on cruise ship A and four on cruise ship B were hospitalized, but thankfully, none died, according to the CDC report.
“According to current CDC requirements, private hot tubs are not required to have automated continuous disinfectant dosing and monitoring or pH monitoring, as is standard for public hot tubs. To meet CDC requirements, private hot tubs must only be shock-chlorinated, drained, and refilled weekly or between occupancies, whichever is sooner,” the CDC report said. “Although the cruise lines adhered to current CDC requirements for operating and maintaining private hot tubs on ships A and B, these measures were insufficient to prevent Legionella growth”.

Why Are Cruise Ship Hot Tubs a Risk?
- Less Stringent Regulations: Private hot tubs on cruise ships are subject to less stringent operating requirements compared to public hot tubs.
- Insufficient Cleaning and Disinfection: Inadequate cleaning and disinfection protocols can allow Legionella bacteria to grow and multiply.
- Vulnerable Population: Cruise ship passengers often include older adults and individuals with underlying health conditions, who are more susceptible to severe infections.
- Protecting Yourself
While it’s important to enjoy your cruise vacation, taking precautions can help minimize your risk of Legionnaires’ disease:
- Avoid Hot Tubs with Cloudy or Scummy Water: This may indicate poor water quality and potential bacterial growth.
- Limit Hot Tub Exposure: If you do choose to use a hot tub, limit your time in the water.
- Shower Before and After Using a Hot Tub: This can help remove bacteria from your skin.
- Stay Informed: Be aware of any health advisories or warnings issued for your cruise ship or destination.
