Cruise ship hot tubs linked to Legionnaires’ disease outbreak, CDC says
Recent reports have indicated that outbreaks of Legionnaires’ disease have been linked to private outdoor hot tubs on U.S. cruise ships. The Centers for Disease Control and Prevention (CDC) released a report last month stating that two cruise ships experienced multiple infections between November 2022 and June 2024, with the hot tubs on the balconies being identified as the source of the outbreaks.
Legionnaires’ disease is a type of pneumonia caused by Legionella bacteria, which thrive in warm water temperatures typically found in hot tubs. The bubbling and aerosolization in hot tubs make it easy for bacteria to be inhaled, leading to infection. Symptoms of Legionnaires’ disease include fever, coughing, difficulty breathing, and chest pain, and can be severe in older individuals and those with weakened immune systems.
To prevent the growth and transmission of Legionella bacteria, the CDC recommends that cruise ship staff follow strict maintenance and operation protocols for private outdoor hot tubs. These measures include maintaining proper water temperature, ensuring residual disinfectant in the water, and using automatic disinfectant dosing systems.
In cases of Legionnaires’ disease, early intervention is crucial for a full recovery. Symptoms typically appear within two to 14 days after exposure, so it is important to seek medical attention if any concerning signs arise. While there are no vaccines for Legionnaires’ disease, maintaining good hygiene standards in hot tubs and avoiding poorly kept facilities can help reduce the risk of infection.
It is essential for individuals at higher risk, such as older adults, smokers, and those with chronic lung conditions, to exercise caution when using hot tubs. Proper maintenance and disinfection of hot tubs can help prevent the transmission of harmful bacteria and viruses, reducing the likelihood of infections like Legionnaires’ disease.
Although Legionnaires’ disease outbreaks linked to cruise ship hot tubs have been reported, improvements in water treatment and monitoring have made such infections less common. By following health guidelines and staying informed about hot tub maintenance practices, individuals can enjoy hot tubs safely while minimizing the risk of bacterial infections.
