20 Nov How Legionella affects building water systems and people
1. Internal and external factors can lead to Legionella growth in building water systems
2. Legionella grows best in large, complex water systems that are not adequately maintained
3. Water containing Legionella is aerosolized through devices
4. People can get sick when they breathe in small droplets of water or accidentally swallow water containing Legionella into the lungs. Those at increased risk are adults 50 years or older, current or former smokers, and people with a weakened immune system or chronic disease
