Legionnaires Disease | FAQ
How does a person get Legionnaires’ disease?
Legionnaires’ disease can be contracted when water droplets containing Legionella bacteria enter a person’s lungs. Cases have also been contracted from Legionella-contaminated water in incisions or skin wounds. Although the vast majority of reported cases of Legionnaires’ disease have been caused by exposure to Legionella-contaminated water, some cases have been contracted in the handling of compost or potting soils. The disease is not contagious.
People can be infected with Legionella while washing their hands or face, brushing their teeth, showering, walking by a decorative fountain, bathing in a whirlpool spa, drinking from a water fountain, working in a building that has fresh air intakes or windows near a cooling tower, receiving respiratory therapy, or handling potting soil or compost.
