Can I get Legionnaires’ Disease from a Hot Tub?

Yes. You can get Legionnaires’ Disease from a hot tub.

While hot tubs can offer therapeutic benefits like relieving stress and easing muscle soreness, if not properly maintained, they can become breeding grounds for Legionella, the bacteria that causes Legionnaires’ disease, a severe, sometimes fatal, form of pneumonia.

Legionnaires’ disease is transmitted through contaminated water vapor, it is not spread through person-to-person contact. Inhaling water mist that contains Legionella bacteria can cause an infection in the lungs. Because of the steam or mist they generate, hot tubs are a common source of Legionnaires’ disease outbreaks.

How Does Legionella Get into Hot Tubs?

Legionella occurs in nature but grows best in warm water especially the temperature range for hot tubs which is usually 96˚F – 104˚F.  But those same temperatures, in fact at any temperature above 78˚F, chlorine, a common disinfectant for hot tubs, begins to breakdown more rapidly rendering it less effective at combating the bacterial load. So, proper maintenance of a hot tub is a balancing act that requires vigilance and regular testing. When outbreaks occur, it’s often the case that one or both of these elements were missing.

A 2018 study called, Legionellosis Associated with Recreational Waters: A Systematic Review of Cases and Outbreaks in Swimming Pools, Spa Pools, and Similar Environments reviewed 22 Legionnaires’ disease outbreaks that occurred between 2006 and 2017. Researchers found that of the hot tubs involved:

  • 31.8 percent had no or inadequate water treatment
  • 31.8 percent had an improper disinfectant level
  • 27.3 percent had no monitoring or recording of parameters
  • 18.2 percent had lack of maintenance, improper cleaning of filters

What are the Symptoms?

Some people are more vulnerable to Legionella infections than others. For example, current and former smokers, people over 50 and people with compromised immune systems are all at elevated risk of contracting Legionnaires’ disease.

Symptoms of an infection, which include headache, muscle aches, fever, shortness of breath and cough, usually develop within two to 14 days of exposure. Most people with Legionnaires’ disease require hospitalization. For about 10 percent of patients, the infection proves fatal.

If you have symptoms of Legionnaires’ disease, see a doctor and mention any possible exposure such as a soak in a hot tub, or a visit to a hospital or hotel.
