But what about the legionella risk of hot tubs and Spas?

What people should be aware of, however, is that hot tubs are probably the greatest source of legionnaires’ disease cases. Legionnaires’ disease is a type of pneumonia that afflicts as many as 18,000 patients every year in the USA alone. Legionnaires’ disease is caused by Legionella, a type of bacteria that naturally thrives in hot or warm water.  So, hot tubs a are an ideal breeding ground for these bacteria. Infection occurs when a person breathes in droplets of water from the mist given off by a contaminated hot tub. The bacteria will happily live and grow in the lungs.

Legionella Risk from Hot Tubs

Legionnaires’ disease is potentially fatal, but it can be treated with antibiotics if proper and timely management of the infection is followed. It can pose serious risks to certain types of patients, including older adults, smokers, people with diabetes, cancer or kidney failure. In fact anyone with a weakened immune system is much more vulnerable to a fatal infection.  Luckily, Legionnaires’ disease does not spread from one person to another.

Protection tips
