Avoid source: Legionnaires' disease is an infection with a legionella bacteria that causes a pneumonia. It is transmitted in a waterborne fashion, often from cooling towers, humidifiers and such. It is not spread person-to-person. It is treated with antibiotics if found. Avoiding the source is the best way to avoid infection. There is no other preventive treatment that I am aware of.

Pretty hard to do: Stay healthy, since most who get "legionaire's disease" are already ill with emphysema, heart failure, or other chronic illnesses. Even then, the risk of any one individual getting this disease is extremely (almost unmeasurably) low. Its wasteful to worry about something for which you have so little risk. Better top think about eating well, exercising regularly, wear seatbelts, don't smoke.

Can someone get legionnaires disease more than once?

Yes: This is a lung infection from inhaling (not person to person contact) the legionella bacteria. Most outbreaks are from plumbing systems in poorly maintained buildings or through contaminated soil (such as gardeners). Like any bacterial infection it can recur. Risk of recurrence increases if you smoke, are older (65 years), have chronic lung disease or repeated exposure.
