How is Legionnaires' disease contracted or spread?

Legionnaires' disease is caused by a bacterium called Legionella, which can be found in water systems. People usually get sick when they breathe in small droplets of water that have the bacteria in them.

Sources of Legionella:

1. Hospitals: According to research, Legionella bacteria can be present in hospital water systems, and special care is needed to prevent its spread in these settings.
2. Tap Water: Recent studies have shown that tap water can sometimes be a source of Legionnaires' disease, especially if the water systems are not properly maintained.
3. In-Hospital Transmission: Other potential ways the disease can spread in hospitals include through systems like air conditioning or other water-related systems.

To prevent the disease, it is important to keep water systems clean and well-maintained, especially in places like hospitals where people might be more likely to get sick.
