What is Legionella?
Legionella is a type of bacteria that can cause Legionnaires' disease, a serious form of pneumonia. It is spread by inhaling small droplets of water containing the bacteria. Everyone can be affected, but some people are at higher risk, including those over 45, smokers, heavy drinkers, and people with weakened immune systems.
How Does Legionella Spread?
Legionella bacteria can grow in any water system, including hot and cold-water systems in homes. The bacteria thrive in water temperatures between 20°C and 45°C. They can multiply in places where water is stagnant and where there is sludge, rust, or scale.
Key Areas of Risk:
- Showers and taps: Spray from these can spread the bacteria.
- Dishwasher and washing machine pipes: These can harbour bacteria if not used regularly.
- Hot water tanks and cylinders: These should be maintained at the correct temperature to prevent bacteria growth.
