It is a bacterial infection of the lungs. Most healthy people exposed to it do not get sick, but the following people may be infected:

People  over 50 year years old


People with a chronic lung disease

People with weak immune systems

People with cancer

People with  diabetes, kidney failure, or liver failure
Legionella is a type of bacterium found in freshwater environments. Thus the key to prevent it is to keep water system clean.
That's right. Legionella grow in water, most of the infections are from warm water shower, hot tub, etc. When the water in any water system is heated to 158 degree Legionella are killed. Any warm water below that temperature is the warm bed for Legionella.
In 2010, the British Health Protection Association found that drivers are five times more likely to suffer from Legionnaires' disease. The main reason may be that the vehicle's wiper tank is filled with water once, and it often takes many days to run out. With residual water, it is easy to incubate the Legionella vulgaris. According to British statistics, more than 20% of Legionnaires' cases are infected through car wiper tanks
